Power Plant Invocations and Imitations of Sonny Karcher

I used to come home from work after Steve Higginbotham dropped me off at the duplex where we were living at the time (see the post Steve Higginbotham and His Junky Jalopy late for the Boiler Blowdown), and my family couldn’t wait to hear what Sonny Karcher had said or done that day.
Sonny Karcher
Soon after I had arrived at the plant one day, after coming back from the coal yard, Sonny had just dropped me off at the front of the Maintenance shop where I was going to the tool room to get some tools for something we were going to do. Sonny was going to drive around behind the tool room in a yellow Cushman cart to pick up some larger equipment, and I was going to meet him there.
Like this only Yellow
As he was backing out of the shop he suddenly made a motion with his left hand. To me it looked like he was making the movement that someone would make if they were taking the lid off of a jar. I thought this meant that he wanted me to do something, but I couldn’t figure out what it was.
Various things went through my head, such as, I should get something to help remove lids from barrels. Or I needed to look inside of a jar to find one of the parts I was going to pick up. Nothing made much sense to me, so I waved for him to come back.
When he did, I asked him what he wanted me to do. He asked me what I meant. I told him that when he made that motion to open a jar, I couldn’t figure out what he wanted. So he told me. “I was just waving goodbye.”
He gave me a big smile and backed out of the shop again. Each time Sonny Karcher waved goodbye, he used a different motion with his hand. Sometimes he would look like he was twirling something on his finger. Sometimes it seemed like he was trying to get something sticky off of his fingers. Sometimes he just drew circles in the air with a couple of fingers. Other times he looked like he was giving an awkward kind of salute. Sonny made an art out of simple things like a wave goodbye.
That first summer it seemed like everyone was always munching on Sunflower seeds. There were bags of sunflower seeds everywhere you looked. Sonny already looked somewhat like a chipmunk with puffy round cheeks that formed from years of wearing a grin on his face. They were extra prominent when his cheeks were full of sunflower seeds. These were seeds still in their shells.
Power Plant Sunflower Seeds
So, it was normal to see someone take a step back while standing around talking, turn their head and drop a few sunflower seed shells from their mouth into the floor drains that were spaced evenly across the maintenance shop floor. There came a time when those drains had to be cleaned out because it seemed that every drain was packed solid full of sunflower seed shells.
Sunflowers weren’t the only items found in the drains, since chewing (or dipping) tobacco (such as Skoal) was used by a lot of the men in the Power Plant.
Just a pinch between your cheek and gums…. Never tried it myself.
Cleaning out a drain full of sunflower seeds, dipping tobacco and spit was a job that might cause a lot of people to gag, and I know I had to fight it back at the time. Most of the time I felt like I was having too much fun to get paid for working at the plant, but when it came time for cleaning out those drains, I felt like I was really working very hard for the $3.89 an hour that I was getting paid my first summer (1979) as a summer help.
But anyway, back to Sonny. I remember one evening when I came home after working with Sonny during the day, and we were sitting around the dinner table eating supper when my dad said something surprising. I don’t remember exactly what he said, but I remember what my response was. It came out before I thought what I was saying, and I said it with the same surprised smile Sonny would have. I replied, “Well S–t the bed!” With a heavy emphasis on each word.
That was a common phrase that Sonny used, and it was his response to anything surprising. Needless to say, I don’t normally use four letter words that have to be edited out of a post. It was just the matter of fact way that Sonny would use that phrase that made it seem all right to say at the time. If I remember correctly, both my mom and my dad stared at me for a second in disbelief, then broke out laughing as they had never heard that particular phrase. It was kind of like hearing “…Bless his heart” for the first time when used following an obvious insult.
In the year 1990 the Power Plant had a program that they called, “We’ve Got the Power”. I will talk more about this in a later post, so I will just say that it was a program where we broke up into teams and tried to find ways to save the company money. But long before “We’ve Got the Power”, there was Sonny Karcher. He was often trying to figure out how we could make electricity cheaper, or even come up with other ways of making a profit.
One day Sonny asked me this, “Kev, your smart because you learn things from all those books at school so tell me this… someone said the other day that diamonds are made out of coal. Is that true?” I told him it was. Then he said, “Well, what if we had one of those big dirt movers full of coal drive over some coal a bunch of times, would we be able to make diamonds?”
Dirt Mover full of coal
I told him that wouldn’t work because it takes a lot more pressure to make a diamond. So, he asked me if it would work if we put some coal on the railroad track and we let an entire train full of coal run over it. Would it make a diamond then? I assured him that even that wouldn’t make a diamond. He accepted it and just said, “Well, it’s too bad since we have that big pile of coal there, we ought to be able to come up with some way of turning them into diamonds.
Another time when we were cleaning out the fish baskets at the intake (a job as smelly as it sounds) next to the 4 big intake pumps. These are the pumps that pump around 189,000 gallons of water per minute each. Sonny told me how big those pumps were and how much water they pumped. Then he said, “You know, that entire boiler is there just to make steam to turn the turbine to make electricity. It seems to me that we could just take these four pumps and have them pump water through the turbine and have it turn the turbines, then we wouldn’t need those big boilers. Why don’t we do something like that?” I assured Sonny that we would never be able to make enough electricity to make up for the electricity it took to turn the pumps that were pumping the water. He shook his head and said that it just seemed to him that those pumps could turn that turbine pretty fast.
One day I watched as Sonny watched another Power Plant man walk into the shop with a new type of lunch box. It was an Igloo Little Playmate. Sonny made a comment about how neat this guy’s new lunch box was. It was a new design at the time.
One exactly like this. These were a new kind of lunch box at the time.
Sonny immediately went out and bought one. The next week he came to work with his shiny new Little Playmate lunch box. I admit. I went and bought one myself a few weeks later. But this was the beginning of a trend that I noticed with Sonny. I began to notice that Sonny seemed to pick one item from each of the people he admired, and went and bought one for himself. Or he would pick up a phrase that someone else would say, and would start using that.
At first I thought it might just be a coincidence, so I started to test my hypothesis. When I would see something new that Sonny brought to work, I would look around to see who else had one of those, and sure enough. Someone close by would have one. Then I would hear Sonny talk a certain way. His accent would change and he would say something like he was imitating someone else, and usually I could tell right away who talked like that and knew that Sonny had borrowed that phrase from that person.
Some may think that this would be annoying, but I think with Sonny it was an act of endearment. It was his way of connecting with those people that he admired. Sonny had a small yellow orange Ford truck and I figured that someone else must have a truck like that, so I started looking all around for one like it. It took me a couple of weeks, but one morning while we were carpooling our way to the power plant, we came up behind the same kind of truck that Sonny had on its way to the plant. It was green instead of yellow, but it was undoubtedly the same model of truck. It was owned by Ken Reece, who was the manager over the tool room and warehouse.
Sonny imitated a voice that had me puzzled for a while. I had checked out all the Power Plant Men around trying to figure out who Sonny was imitating. Every once in a while Sonny would change his way of talking when he was making a point where he would let his lower lip come forward and work its way left and right as he talked, and he would close one eye more than the other and talk in a strange sort of a southern drawl. I just knew he was imitating someone because it was so different than just the regular Sonny.
Finally, one day when I was walking through the shop I heard someone in the welding area talking just like Sonny would talk when he used that voice. There was no mistake. That had to be the person. I could hear every inflection in his voice and it had to be the voice that Sonny was imitating because it had been much more honed and refined to give just the right effect. So, I changed the course I was travelling so that I could make my way around to the welders to see who it was that was talking like that.
There in the middle of the welding shop was a heavier set man standing in the middle of a group of welders telling a story. Everyone was listening to him quietly just as if it was story time at the library. So, I stopped and watched. This man wasn’t wearing an Electric Company hard hat. He was wearing a Brown and Root hard hat, which indicated that he worked for the construction company that was building the plant.
This guy was undoubtedly a master storyteller. When it came to the climactic part of the story, the bottom of his mouth would stick out with his lip moving left and right and left again, and one eye was partially closed to show the intensity of the situation and the drawl would intensify. Finally. I had found the man that Sonny Karcher had admired enough to take one of his favorite traits and connect it to himself. I could see why Sonny admired him so much. He had everyone within listening distance captivated by his story.
This Brown and Root hand soon became an employee of the Electric Company within a couple of weeks after I left at the end of the summer (on September 9, 1979). This heavier set person was still working at the plant when I first posted this story last year, but has since retired. He was one of this country’s leading Turbine mechanics and he can still tell a story like no one else. He is no longer as heavy. He is rather thin in comparison. He improved his health after realizing that if he really loved his family, he needed to take better care of himself.
I consider this True Power Plant Man, Ray Eberle, to be a dear friend of mine. I have never met anyone that looked more like my own grandfather than Ray. Not that he was that much older. No. He looked almost exactly like my grandfather looked when he was Ray’s age. There was no nicer man than my dad’s dad, and there is no nicer Power Plant Man than Ray Eberle.

It’s both amusing, and comforting to know the same things happen at power plants everywhere, we went through a “sunflower seed phase” which plugged the drains & the plant finally came up with a “NO MORE SUNFLOWER SEEDS” rule!
Lifecycle of a Power Plant Lump of Coal
Originally posted August 16, 2013:
Fifty Percent of our electricity is derived from coal. Did you ever wonder what has to take place for that to happen? I thought I would walk through the lifecycle of a piece of coal to give you an idea. I will not start back when the it was still a tree in a prehistoric world where dinosaurs grew long necks to reach the branches. I will begin when the large scoop shovel digs it out of the ground and loads it onto a coal truck.
The coal is loaded onto trucks like these before it is dumped onto the train cars. This photo was found at http://www.gillettechamber.com/events/eventdetail.aspx?EventID=2827
The coal for the power plant in North Central Oklahoma came from Wyoming. There were trains from the Black Thunder Mine and the Powder River Basin.
Coal Trains on their way to power plants
It’s a long ride for the lump of coal sitting in the coal train on it’s way to Oklahoma. Through Nebraska and Kansas. It’s possible for the coal to be visited by a different kind of traveler. One that we may call “A tramp.” Someone that catches a ride on a train without paying for the ticket.
One time a tramp (or a hobo, I don’t remember which), caught a ride on one of our coal trains. They forgot to wake up in time, and found their self following the lumps of coal on their next phase of the journey. You see. Once the coal reached the plant, one car at a time enters a building called the “Rotary Dumper”.
A rotary dumper much like the one that was at our Power Plant
As each train car enters the dumper four clamps come done on the car and it rolls upside down dumping the coal into a bin below. Imagine being a tramp waking up just in time to find yourself falling into a bin full of coal. with a car full of coal dumping coal on top of you. One coal car contained 102 tons of coal (today they carry 130 tons). Today one train contains 13,300 tons of coal. This is over 26 million pounds of coal per train.
Miraculously, this passenger survived the fall and was able to call for help or someone saw him fall. He was quickly rescued and brought to safety. Needless to say, the tramp went from being penniless to being, “comfortable” very quickly. I don’t know that it made the news at the time. I think the electric company didn’t want it to become “viral” that they had dumped a hobo into a coal bin by accident. Well. They didn’t know what “going viral” meant at the time, but I’m sure they had some other phrase for it then.
Ok. Time for a Side Story:
Since I’m on the subject of someone catching a clandestine ride on a train, this is as good of a place as any to sneak in the tragic story of Mark Meeks. Well. I say it was tragic. When Mark told the story, he seemed rather proud of his experience. You see. Mark was a construction electrician. He hired on as a plant electrician in order to settle down, but in his heart I felt like he was always a construction electrician. That is, he didn’t mind moving on from place to place. Doing a job and then moving on.
Mark explained that when he was working at a construction job in Chicago where he worked for 2 years earning a ton of overtime, he figured that by the time he finished he would have saved up enough to buy a house and settle down. He was married and living in an apartment in Chicago. He didn’t spend much time at home as he was working 12 hour days at least 6 days each week. He figured that was ok, because when he was done, he would be set for life.
Unknown to him at the time, each morning when he woke up before the crack of dawn to go to work, his wife would drive to O’Hara airport and catch a plane to Dallas, Texas where she was having an affair with some guy. By the time Mark returned from work 14 hours later, she was back home. Each day, Mark was earning a ton of overtime, and his wife was burning it on airline tickets.
When the two years were over, Mark came home to his apartment to collect his wife and his things and go live in peace in some small town some where. That was when he learned that his wife had been having the affair and using all his money to do it. She was leaving him. Penniless.
Completely broke, Mark drifted around for a while. Finally one day he saw a train that was loaded down with wooden electric poles. Mark figured that wherever those poles were going, there was going to be work. So, he hopped on the train and traveled all the way from Minneapolis Minnesota riding in the cold, wedged between some wooden poles on one of the cars on the train.
The train finally arrived at its destination somewhere at a port in the Gulf of Mexico. I don’t remember if it was Mississippi or Louisiana. He watched as they unloaded the poles, waiting to see what jobs were going to be needed for whatever the poles were for. He watched as they took the large wooden poles and piled them up in the ocean. They were using them to build up the shoreline. There were no jobs.
It is when you have been beaten down to the point of breaking when you reach a very important point in your life. Do you give up, or do you pick yourself up and make something of yourself? Mark chose the latter. He was a natural fighter. He eventually ended up at our plant as contract help, and then was hired as a plant electrician.
End of side story.
Let’s follow the lump of coal after it is poured out of the coal train in the dumper…
The coal is fed onto a conveyor belt. Let’s call this Conveyor 1, (because that is what we called it in the plant). This has a choice to feed it onto belt 2 which leads up to the stack out tower, or it can feed the other way to where some day it was planned to add another conveyor with another stackout tower. This was going to go to a pile of coal for two other units that were never built.
Anyway, when the coal drops down on Conveyor 2, way under ground, it travels up to the ground level, and continues on its way up to the top of the stackout tower where it feeds onto Belt 3. Belt 3 is a short belt that is on an arm that swings out over the coal pile. The coal is fed onto the coal pile close to the stack out tower. I suppose it is called stack out, because the coal is stacked up next to the tower.
A view of the coalyard from the top of the Smoke Stack. The tower with the conveyor running up to the top is the stack out tower. Belt 3 is the arm pointing to the right in this picture
Anyway, there are large dozers (bulldozers) and dirt movers that pickup the coal and spread it out to make room for more coal from more coal trains. As mentioned above. One train now carries 26 million pounds of coal.
Dirt Mover full of coal
the coal that is spread out on the coal pile has to stay packed down otherwise it would spontaneously combust. That is, it would catch on fire all by itself. Once coal on a coal pile catches on fire it is impossible to “reasonably” put out. You can spray all the water on it you want and it won’t go out. When a fire breaks out, you just have to drag the burning coal off of the pile and let it burn out.
In order to keep the coal from performing spontaneous combustion, the dirt movers kept it packed down. As long as the coal is packed tight, air can’t freely reach the buried coal, and it doesn’t catch fire. So, dirt movers were constantly driving back and forth on the coal pile to keep the coal well packed. Even on the picture of the coalyard above from the smoke stack, you can see two pieces of heavy equipment out on the coal pile traveling back and forth packing the coal.
Anyway, the next phase in the life of the lump of coal happens when it finds itself directly under the stack out tower, and it is fed down by a vibratory feeder onto a conveyor. In our plant, these belts were called, Belts 4, 5, 6 and 7. Belts 4 and 5 fed onto Belt 8 and belts 6 and 7 fed onto belt 9.
Belts 8 and 9 brought the coal up from under the coal pile to the top of the Crusher tower. In the picture above you can see that tower to the right of the stack out tower with the long belts coming from the bottom of the tower toward the plant. The crusher tower takes the large lumps of coal that can be the size of a baseball or a softball and crushes it down to the size of marbles and large gumballs.
Coal conveyor carrying coal to the coal silos from the coalyard. This is the size of the coal after it has been crushed by the crusher
From the crusher tower the lump of coal which is now no more than a nugget of coal travels from the coal yard up to the plant on belts 10 and 11.
conveyor 10 and 11 are almost 1/2 mile long
Up at the top of this belt in the distance you can see another tower. This tower is called the Transfer tower. Why? Well, because it transfers the coal to another set of belts, Belt 12 and 13. You can see them going up to the right to that tower in the middle between the two boilers.
The tower between the two boilers is called the Surge Bin tower. That basically means that there is a big bin there that can hold a good amount of coal to feed to either unit. At the bottom of the white part of the tower you can see that there is a section on each side. This is where the tripper galleries are located. There are two belts in each tripper, and two belts that feed to each tripper belt from the surge bin. So, just to keep counting, Belts 14 and 15 feed to unit one and belts 16 and 17 feed to unit 2 from the surge bin. then Belts 18 and 19 are the two tripper belts that dump coal into the 6 silos on unit one, while belts 20 and 21 feed the silos on unit 2.
Once in the Coal silos, the coal is through traveling on belts. The silos are positioned over things called bowl mills. The coal is fed from the silo into the bowl mill through something called a Gravimetric feeder, which is able to feed a specific amount of coal into the bowl mill. This is the point that basically decides how hot the boiler is going to be.
Once the coal leaves the gravimetric feeder and drops down to the bowl mill, it is bound for the boiler. The gravimetric feeder is tied right to the control room. When they need to raise load more than just a minimal amount, a control room operator increases the amount of coal being fed from these feeders in order to increase the flow of coal into the boiler….. I don’t know… maybe it’s more automatic than that now…. The computer probably does it these days.
When the nugget of coal falls into the bowl mill the long journey from the coal mine in Wyoming is almost complete. Its short life as a nugget is over and it is pulverized into powder. The powder is finer than flour. Another name for a bowl mill is “Pulverizer”. The coal comes from the Powder River Basin in Wyoming and just before it is consumed in Oklahoma it really does become powder.
Big rollers are used to crush the coal into fine particles. The pulverized coal is blown up pipes by the primary air fans and blown directly into the boiler where they burst into flames. A bright orange flame. The color reminds me of orange sherbet Ice cream.
The color of the fireball in the boiler
At this point an incredible thing happens to the coal that so many years ago was a part of a tree or some other plant. The chemical process that trapped the carbon from the carbon dioxide millions of years earlier is reversed and the carbon is once again combined to the oxygen as it was many millennium ago. A burst of heat is released which had been trapped after a cooling effect below the tree as it sucked the carbon out of the environment way back then.
The heat is transferred to the boiler tubes that line the boiler. The tubes heat the water and turn it into steam. The steam shoots into the turbine that turns a generator that produces the electricity that enters every house in the country. The solar power from eons ago that allowed the tree to grow is being used today to power our world. What an amazing system.
To take this one step further, the carbon dioxide that is released into the atmosphere today is replenishing the lost carbon dioxide from many years ago. Back when plants could breathe freely. Back before the carbon dioxide level was depleted almost to the point of the extinction of plant life on this planet. Remember, what we look on as a pollutant and a poison, to a plant is a chance to grow. The Sahara desert used to be a thriving forest. Maybe it will be again some day.
So, there is the question of global warming. We humans are so short sighted sometimes. We want to keep everything the same way we found it when we were born. We try desperately to keep animals from becoming extinct. We don’t think about the bazillions (ok, so I exaggerate) of animals that were extinct long before man arrived. It is natural for extinction to occur. That is how things evolve. We are trying to keep a system the same when it has always been changing.
Years from now we may develop ways to harness the energy from the sun or even from the universe in ways that are unimaginable today. When that time arrives, let’s just hope that we remain good stewards of the world so that we are around to see it. I believe that the use of fossil fuels, (as odd as that may seem) is a major step in reviving our planet’s natural resources.

Glad Mark fought the good fight, still a sad story.

Great read. I love knowing how things work. As I read the sad story of the traveling electrician, I kept wondering if she could have pulled that off in today’s world of air travel.
when I went to the Christian College in Eugene Oregon, they forced me to take a course in biology at the University of Oregon. I willingly sat and listened to the mix of science and evolution. I admit their perspective was intriguing.
at the end of the class, the last day, the instructor asked each one of her students to tell how the class had affected their thinking.
each one gave the politically correct answer in a variety of form. all the while I sat joyfully waiting my turn.
my response hushed the class for a moment. (it’s been some decades ago so I have to paraphrase but let it be sufficient) “I’m impressed with all the material you’ve covered. it’s astounding to think of all the things that were. but for me this class has only glorified my God. because I realize that in his wisdom he created gasoline for my car.”
you’ve covered a lot of material in your post. and I’m impressed at your diligence to complete it. I thank God for His faithfulness that he has put into you. may He prosper your testimony for the glory of His Holy Son.

We processed several hobo’s through our coal system, & injured a few, but none ever got anything from the power company. I remember we would always worried about finding a chunk of scalp or something in the grating where the tripper car drops coal down into the silo. One especially memorable event was when a coal yard operator found a down vest jacket on the coal pile and bragged about how lucky he was to find this jacket, the size even fit, but the jacket did smell a little funny. yes it was ripped off the body of a hobo by the plow above conveyor one & shot out onto the coal pile by the stackout conveyor.
It was always unnerving to have a pull cord go down in the middle of the night deep down in the coal trestle, while the belts were shut down. You’d have to go down there alone, in the dark & reset the pull cords, so the belts could be started later when needed. You knew it wasn’t a trick because the whole crew had been up in the control room together eating dinner or something. You always wondered if you might run into a real hobo – or the ghost of one.
When Power Plant Durability and Automation Goes Too Far
Everyone expects when they enter an elevator and push a button for the 3rd floor that when the doors open they will find themselves on the third floor. It doesn’t occur to most people what actually has to happen behind the scenes for the elevator to go through the motions of carrying someone up three stories. In most cases you want an automated system that requires as little interaction as possible.
I have found while working in the Coal-fired Power Plant in North Central Oklahoma that some systems are better off with a little less than perfect automation. We might think about that as we move into a new era of automated cars, robot soldiers and automatic government shutdowns. Let me give you a for instance.
The coal trains that brought the coal from Wyoming all the way down to the plant would enter a building called “The Dumper.” Even though this sounds like a less savory place to park your locomotive, it wasn’t called a Dumper because it was a dump. It was called a Dumper because it “Dumped.” Here is a picture of a dumper:
A rotary dumper much like the one that was at our Power Plant
The coal train would pull into this room one car at a time. I talked about the dumper in an earlier post entitled “Lifecycle of a Power Plant Lump of coal“. As each car is pulled into this building by a large clamp called the “Positioner” (How is that for a name? It is amazing how when finding names for this particular equipment they decided to go with the “practical” words. The Positioner positions the coal cars precisely in the right position so that after the car clamps come down on the car, it can be rotated upside down “Dumping” the coal into the hoppers below. No fancy names like other parts of the power Plant like the “Tripper Gallery” or the “Generator Bathtub” here.
A typical coal train has 110 cars full of coal when it enters the dumper. In the picture of the dumper above if you look in the upper left corner you will see some windows. This is the Dumper Control Room. This is where someone sits as each car pulls through the dumper and dumps the coal.
Not long after the plant was up and running the entire operation of the dumper was automated. That meant that once put into motion, the dumper and the controls would begin dumping cars and continue operating automatically until the last car was through the dumper.
Let me try to remember the sequence. I know I’ll leave something out because there are a number of steps and it has been a while since I have been so fortunate as to work on the dumper during a malfunction… But here goes…
I remember that the first coal car on the train had to positioned without the positioner because… well….. the car directly in front of the first car is, of course, the locomotive. Usually a Burlington Northern Santa Fe Engine.
A picture from Shutterstock of a locomotive pulling a coal train
Before I explain the process, let me show you a picture of the Positioner. This the machine that pulls the train forward:
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
The automation begins after the first or second car is dumped. I’ll start with the second car just finishing the process as it rolls back up right after dumping the coal… The car clamps go up.
- The rear holding arm (that holds the car in place from the entrance side of the dumper) lifts up out of the way.
- The Positioner begins pulling the entire train forward.
- Electric eyes on both end of the dumper detect when the next car has entered the dumper.
- The Positioner adjusts the position of the coal car to the exact position (within an inch or two) by backing up and pulling forward a couple of times.
- The Holding arm on the back end comes down on the couplings between the two train cars one back from the car that is going to be dumped.
- The four car clamps come down on the train car at the same time that the dumper begins rotating.
- The Positioner clamp lifts off of the train car couplings.
- Water Sprayers come on that are attached to the top of the dumper so that it wets the coal in order to act as a dust suppression.
- The Positioner travels back to the car clamp between the car that was just emptied before and the car in front of it.
- As the train car rotates to the desired angle. (I think it’s about 145 degrees), it begins slowing down.
- When the car has been rotated as far as desired it comes to a stop.
- The Dumper pauses for a few seconds as all the coal is dumped from the coal car.
- The Positioner moves back and forth until it is in just the right position for the positioner arm to lower onto the couplings between the cars.
- The Sprayers turn off.
- The Dumper begins returning to an upright position.
- The Positioner arm lowers down onto the clamps between the coal cars.
- Once the car is upright the dumper stops rotating.
- The 4 car clamps go up.
- The Holding arm goes up. And the process is repeated.
This is a beautiful process when it works correctly. Before I tell you about the times it doesn’t work correctly, let me tell you about how this process was a little…uh… too automated…
So. The way this worked originally, was that once the automated process was put into operation after the second car had been dumped, all the dumper control room operator had to do was sit there and look out the window at the coal cars being dumped. They may have had some paperwork they were supposed to be doing, like writing down the car numbers as they pulled through the dumper. It seems that paperwork was pretty important back then.
Each car would pull through the dumper… The coal would be dumped. The next car would be pulled in… etc.
Well. Trains come from Wyoming at any time of the day. Train operators were paid pretty well, and the locomotive engineers would come and sit in the control room while the train was being dumped. Often (more often than not it seemed) the trains would pull into the dumper in the middle of the night. Coalyard operators were on duty 24 by 7.
So, imagine this…. Imagine Walt Oswalt… a feisty sandy haired Irishman at the dumper controls around 3 in the morning watching 110 cars pull through the dumper. Dumping coal…. One after the other. I think the time it took to go from dumping one car to the next was about 2 1/2 minutes. So it took about 3 1/2 hours to dump one train (I may be way off on the time… Maybe one of the operators would like to leave a comment below with the exact time).
This meant that the dumper operator had to sit there and watch the coal cars being slowly pulled through the dumper for about 3 hours. Often in the middle of the night.
For anyone who is older than 30 years, you will remember that the last car on a train was called a Caboose. The locomotive engineers called it a “Weight Car”. This made me think that it was heavy. I don’t know. It didn’t look all that heavy to me… You decide for yourself:
A Caboose
Back in those days, there was a caboose on the back of every train. A person used to sit in there while the train was going down the tracks. I think it was in case the back part of the train accidentally became disconnected from the front of the train, someone would be back there to notice. That’s my guess. Anyway. Later on, a sensor was placed on the last car instead of a caboose. That’s why you don’t see them today. Or maybe it was because of something that happened one night…
You see… it isn’t easy for Walt Oswalt (I don’t mean to imply that it was Walt that was there that night.. well… it sounds like I’m implying that doesn’t it…. I use Walt when telling this story because he wouldn’t mind. I really don’t remember who it was) to keep his eyes open and attentive for 3 straight hours. Anyway… One night while the coal cars were going through the dumper automatically being dumped one by one… there was a point when the sprayers stopped spraying and the 4 car clamps rose, and there there was a moment of pause, if someone had been there to listen very carefully, they might have heard a faint snoring sound coming from the dumper control room.
That is all fine and dandy until the final car rolled into the dumper. You see… One night…. while all the creatures were sleeping (even a mouse)… the car clamps came down on the caboose. Normally the car clamps had to be raised to a higher position to keep them from tearing the top section off of the caboose.
If it had been Walt… He woke when he heard the crunching sound of the top of the caboose just in time to see the caboose as it swung upside down. He was a little too late hitting the emergency stop button. The caboose rolled over. Paused for a moment as the person manning the caboose came to a rest on the ceiling inside… then rolled back upright all dripping wet from the sprayer that had meant to keep down the dust.
As the car clamps came up… a man darted out the back of the caboose. He ran out of the dumper…. knelt down… kissed the ground… and decided from that moment on that he was going to start going back to church every Sunday. Ok. I exaggerate a little. He really limped out of the dumper.
Needless to say. A decision had to be made. It was decided that there can be too much automation at times. The relay logic was adjusted so that at the critical point where the dumper decides to dump a coal car, it had to pause and wait until the control room operator toggled the “Dump” switch on the control panel. This meant that the operator had to actively decide to dump each car.
As a software programmer…. I would have come up with another solution… such as a caboose detector…. But given the power that was being exerted when each car was being dumped it was probably a good idea that you guaranteed that the dumper control room operator actually had his eyeballs pointed toward the car being dumped instead of rolled back in his head.
I leave you with that thought as I go to another story. I will wait until another time to talk about all the times I was called out at night when the dumper had failed to function.
This is a short story of durability…
I walked in the electric shop one day as an electrician trainee in 1984 to find that Andy Tubbs had taken an old drill and hooked it up to the 480 volt power source that we used to test motors. Ok. This was an odd site. We had a three phase switch on the wall with a fairly large cable attached with three large clips so we could hook them up to motors that we had overhauled to test the amperage that they pulled to make sure they were within the specified amount according to their nameplate.
I hesitated a moment, but I couldn’t resist…. I had to ask, “Andy…. Why have you hooked up that old drill to 480? (it was a 120 volt drill). He replied matter-of-factly (Factly? Can I really say that in public?), “I am going to burn up this old drill from the Osage Plant (See “Pioneers of Power Plant Fame Finally Find Peace” for more information about Osage Plant) so that I can turn it in for a new one.
Ok. I figured there must be a policy somewhere that said that if you turned in a burned up tool they would give you a new one. I knew that Bud Schoonover down at the toolroom was always particular about how he passed out new tools (I have experienced the same thing at my new job when trying to obtain a new security cable for my laptop).
Anyway. Andy turned the 480 volts on and powered up the drill. The drill began whining as it whirled wildly. Andy stood there holding up the drill as it ran in turbo mode for about five minutes. The drill performed like a champ.
Old Power Drill
After showing no signs of burning itself up running on 480 volts instead of 120 volts, Andy let off of the trigger and set it back on the workbench. He said, “This is one tough drill! I think I’ll keep it.” Sure. It looked like something from the 1950’s (and it probably was). But, as Andy said, it was one tough drill. On that day, because of the extra Durability of that old Pioneer Power Plant Drill, Andy was robbed of a new variable speed, reversible drill that he was so craving.

Great stories!
Coal trains today have engines at the rear of the train. I hope we never try to dump one of them!
It takes about 7 hrs to dump 150 car train
Wasn’t Walt but a certain marine we won’t mention. They dumped the last car & forgot to put the car clamps in the up maximum position. They give the go ahead for the train to pull the caboose through! Instant convertible caboose! Now there are break away clamps on the north side. And there are locomotives on the rear of the train because the trains are made up of 150 cars .
Like you, I can think of several ways to automate the process without dumping the caboose but I think the operator pushing the button may be the best. Automation can get out of hand.
An engineer used to remind us: “A machine always does what you tell it to…whether you want it to, or not.”
IF the union or the lawyers require a duty operator on an automated process, I’m all for giving him a button to push and attaching some responsibility. All automation designs are approved by Murphy…Wow! Thanks for the update Bruce!
Power Plant Spider in the Eye
If you have been following my posts for very long, you may have the idea that I just like to write posts about spiders. After writing two posts about Spider Wars (see posts: “Power Plant Spider Wars and Bugs in the Basement” and “Power Plant Spider Wars II – The Phantom Menace“), another post about spiders just seems like a bit much. Even though there is a spider in this story, another appropriate title could be something like “Another night in the Life of a Power Plant Electrician”. Without further ado, here is the story.
Ninety nine times out of a hundred, when the phone rang in the middle of the night, it was the Power Plant in North Central Oklahoma calling. I don’t remember a time when the Shift Supervisor on the other end of the phone wasn’t very polite. They knew they were waking someone from their sleep to ask them to drive 30 miles out to the plant in the wee hours of the morning.
The Shift Supervisor, whether it was Joe Gallahar, Jim Padgett, Jack Maloy, or Gary Wright, they would all start out with something like, “Hey, sorry to wake you buddy…”. After such an apologetic introduction, how could you be upset that your sleep had just been interrupted? Then they would proceed to tell you why they needed your assistance. For me, it was usually because the coal dumper had stopped working while a train was dumping their coal. This meant that 110 cars tied to three or four engines was sitting idle unable to move.
Each car on the train would be dumped one at a time as it was pulled through the rotary dumper. The process was automated so that the operator in the control room watching out of the window only had to push one switch to dump each car.
A rotary dumper much like the one that was at our Power Plant
The train would move forward to the next car automatically as a large arm on a machine called a Positioner would come down on the coupling between the cars and pull the entire train forward to the next car.
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
There were so many moving parts involved in positioning the car in place and rolling it over to dump the coal, that it was common for something to go wrong. When that happened the entire process would come to a halt and the train would just have to sit there until someone came to fix it. That was usually an electrician since the dumper and the positioner was all controlled by relays much like the elevator controls, only more complicated.
This particular night, Joe Gallahar had called me. It seemed that there was an intermittent problem with the dumper that didn’t seem to make much sense and they couldn’t figure out why it was acting so strange. One of the train cars had actually been damaged as the positioner arm would start coming up from the coupling to the point where the holding arm on the other end of the dumper had come up, then the positioner arm began going back down, causing the train to move on it’s own only to have the arm on the positioner scrape the side of the train car as it rolled backward uncontrolled.
Though it was less frequent, it was not so strange to have a train damaged by erratic dumper controls. I have seen the side of a train car smashed in by the positioner arm when it decided to inappropriately come down. This night, the problem was acting like that. So, instead of damaging the train further, they decided to call me out to have a look at it.
I always had the philosophy when being called out in the middle of the night to be just as polite back to the Shift Supervisor when I answered the phone. I had a Marketing professor at Oklahoma State University named Dr. Lee Manzer, who explained this one day.
Here is a short side story about Dr. Manzer —
Dr. Manzer told a story in class one day about how he was travelling home one day from a long and difficult trip where everything had gone wrong. It was very late at night when he arrived at his house (which, incidentally was just down the street from my parent’s house), he was really beat. He went into his bedroom and began preparing for bed.
About the time he was taking off his tie, his wife rolled over in bed and welcomed him home. Then she said, “Oh, by the way. I forgot to buy milk (or maybe it was ice cream). Do you think you could run down to the store and buy some?”
Dr. Manzer explained his decision making process at that point like this: “I could either go on a rant and tell my wife what a long and tiring day I had just had and now you are asking me to go buy milk? , and then I would go get the milk. Or I could say, ‘Of course Dear. I would be glad to go buy some milk.’ Either way, I was going to go buy the milk. So, I could do it one of two ways. I could complain about it or I could be positive. I could either score points or lose them…. hmm…. Let’s see…. what did I do? I said, ‘Of course Dear.'”
— End of the side story about Dr. Lee Manzer who by the way was a terrific Marketing Professor. I understand he still teaches to this day.
So, when Joe Gallahar called me that night, and explained that the dumper was acting all erratic, Instead of saying “Yes Dear.” as that wouldn’t have been appropriate, I told him, “No problem. I’ll be there as soon as I can.” My wife Kelly knew who was on the other end of the phone when she heard my answer. She had heard it many times before. I usually only had to say one word after hanging up the phone, “Dumper”, and she knew what that meant.
A Power Plant Electrician’s spouse knows that this is part of the job. As I pulled on the jeans that I had laid out before I went to bed, Kelly would usually say something in her sleep like, “Be careful”. I would give her a hug and tell her I’ll be back in a while, even though, sometimes I would be gone for two days working on the precipitator during a start up or some major catastrophe. Usually, it was just a couple of hours before I came crawling back in bed.
This particular night I drove to work in silence with the window open so that the cool air would keep me awake. Normally I had the radio on some rock station so that I would be singing along (in my terribly off-key singing voice) in order to stay awake. Sometimes I would just take the 25 minutes of silence to just think.
My thought that night was that it was nice to be wanted. There is some comfort in knowing that the Shift Supervisor could call me with enough confidence to know that I would be able to come out on my own and fix a problem that was costing the company a large amount of money each hour the dumper was offline. Some might think that I would be annoyed to be wakened in the middle of the night to go fix something at the plant. That night, as most nights I was feeling honored.
That wasn’t always the case, and I’ll soon write a post about another call out in the middle of the night where Scott Hubbard and I wondered exactly why they called us… but that’s another story.
When I arrived at the plant, I rolled my car up to the speaker at the front gate and said, “Hello” with an arrogant English accent. I don’t know why, but I always liked doing that. I think it was Billy Epperson who answered back. I told him I was here to work on the dumper. He thanked me and opened the gate and I drove the 1/2 mile down the hill to the plant parking lot. As I went over the hill, in the moonlight I could see the train up at the coal yard looking like a long silver snake.
I walked into the maintenance shop and grabbed a truck key off of the hook and drove around to the electric shop to pick up my hard hat and tool bucket.
This is an actual picture of my tool bucket
I took the long way around to the coal yard since the train blocked the shortest route. We had a tunnel on the west end of the coal yard that went under the tracks for just this occasion.
When I arrived at the dumper, Stanley Robbins explained that he had tried troubleshooting this problem himself, but he couldn’t find anything that would explain the strange behavior. Since the last downsizing, we were all able to sort of mix our skills so that an operator could do simple electric tasks if they felt comfortable with it. Stanley knew enough to fix your normal minor dumper issues. This one was a little different.
Since I had been an electrician for the past 15 years at this point, I felt pretty confident that I would quickly find the problem and be heading back home soon. So, I walked into the dumper switchgear where the dumper controls are found. I asked Stanley to go turn on the power to the dumper so that I could watch the relays. When the power was on, I began tracing the circuits looking for the point of failure.
The problem was intermittent, and when Stanley started the dumper back up, everything seemed to be working just fine. Stanley explained that this was why they couldn’t use the dumper because they couldn’t be sure when it was going to malfunction. They had even uncoupled the train and pulled it apart right where the positioner arm was so that I could see what was happening.
Using radios (walkie talkies), I asked Stanley to move the positioner arm up and down while I checked it. He lowered it and raised it back up without any problem. When he began lowering it the second time, it suddenly stopped halfway down. Watching the controls, I could see that it indicated that it had come all the way down. It would be this case that would tell the holding arm on the far side of the dumper to go back up, which is what happened when the train rolled back earlier that night.
Then the relays rattled like they were picking up and dropping out rapidly. Then the problem cleared up again. Somehow the positioner arm had thought it had come down on the car clamps when it was still up in the air. That was not likely to happen because when something fails it usually doesn’t see what it’s supposed to see, not the other way around. It doesn’t usually see something that isn’t there.
So, I had Stanley lower the positioner arm down so that it was level with the ground, so that I could check the connections to the electric eye that was on the positioner clamp that detected the train car clamp when it came down. I couldn’t find any lose connections or anything that would explain it.
So I told Stanley that I was going to look up from under the car clamp to look at the electric eye. So, I asked him to kill the power to the positioner so that it wouldn’t move while I was doing that and crush me like a bug. Kneeling on the train track, I took my flashlight and looked up at the electric eye from under the car clamp, and this is what I saw:
A spider almost like this
This spider had built a spider web in front of the electric eye on the positioner and was sitting right in the middle causing the positioner to think it was down on the car clamp when it wasn’t. Stanley was watching me from the window of the dumper control room when he saw me stand up quickly and look up at him with a big grin on my face. I gave him a thumbs up.
You know the phrase, “Everyone has 10 minutes of fame….” It indicates that some time in most people’s lives they are famous for a brief moment. It may or may not define the rest of their life. Well. This was that spiders claim to fame. This one spider had successfully stranded a coal train with 110 cars of coal. A train crew, a coal yard operator, and one lone electrician that had traveled 30 miles to watch it act out it’s drama of catching gnats on it’s web being constantly watched by one large electric eye.
I did not drive home in silence that early morning. I laughed out loud all the way home. I still laugh to myself to this day when I think about this night. Phrases like, “Isn’t life wonderful” comes to my mind. Or “Even Spiders desire attention every now and then.” Could there have been a better malfunction than to have a spider dancing in front of an electric eye out in the plains of Oklahoma saying, “Look at me! Look at me!” and by golly. Someone did! I’m just glad it was me.
Power Plant Invocations and Imitations of Sonny Karcher

I used to come home from work after Steve Higginbotham dropped me off at the duplex where we were living at the time, and my family couldn’t wait to hear what Sonny Karcher had said or done that day.
Sonny Karcher
Soon after I had arrived at the plant one day, after coming back from the coal yard, Sonny had just dropped me off at the front of the Maintenance shop where I was going to the tool room to get some tools for something we were going to work on. Sonny was going to drive around behind the tool room in a yellow Cushman cart to pick up some larger equipment, and I was going to meet him there.
Like this only Yellow
As he was backing out of the shop he suddenly made a motion with his left hand. To me it looked like he was making the movement that someone would make if they were taking the lid off of a jar. I thought this meant that he wanted me to do something, but I couldn’t figure out what it was.
Various things went through my head, such as, I should get something to help remove lids from barrels. Or I needed to look inside of a jar to find one of the parts I was going to pick up. Nothing made much sense to me, so I waved for him to come back.
When he did, I asked him what he wanted me to do. He asked me what I meant. I told him that when he made that motion to open a jar, I couldn’t figure out what he wanted. So he told me. “I was just waving goodbye.”
He gave me a big smile and backed out of the shop again. Each time Sonny Karcher waved goodbye, he used a different motion with his hand. Sometimes he would look like he was twirling something on his finger. Sometimes it seemed like he was trying to get something sticky off of his fingers. Sometimes he just drew circles in the air with a couple of fingers. Other times he looked like he was giving an awkward kind of salute. Sonny made an art out of simple things like a wave goodbye.
That first summer it seemed like everyone was always munching on Sunflower seeds. There were bags of sunflower seeds everywhere you looked. Sonny already looked somewhat like a chipmunk with puffy round cheeks that formed from years of wearing a grin on his face. They were extra prominent when his cheeks were full of sunflower seeds. These were seeds still in their shells.
Power Plant Sunflower Seeds
So, it was normal to see someone take a step back while standing around talking, turn their head and drop a few sunflower seed shells from their mouth into the floor drains that were spaced evenly across the maintenance shop floor. There came a time when those drains had to be cleaned out because it seemed that every drain was packed solid full of sunflower seed shells.
Sunflowers weren’t the only items found in the drains, since chewing (or dipping) tobacco (such as Skoal) was used by a lot of the men in the Power Plant.
Just a pinch between your cheek and gums…. Never tried it myself.
Cleaning out a drain full of sunflower seeds, dipping tobacco and spit was a job that might cause a lot of people to gag, and I know I had to fight it back at the time. Most of the time I felt like I was having too much fun to get paid for working at the plant, but when it came time for cleaning out those drains, I felt like I was really working very hard for the $3.89 an hour that I was getting paid my first summer (1979) as a summer help.
But anyway, back to Sonny. I remember one evening when I came home after working with Sonny during the day, and we were sitting around the dinner table eating supper when my dad said something surprising. I don’t remember exactly what he said, but I remember what my response was. It came out before I thought what I was saying, and I said it with the same surprised smile Sonny would have. I replied, “Well S–t the bed!” With a heavy emphasis on each word.
That was a common phrase that Sonny used, and it was his response to anything surprising. Needless to say, I don’t normally use four letter words that have to be edited out of a post. It was just the matter of fact way that Sonny would use that phrase that made it seem all right to say at the time. If I remember correctly, both my mom and my dad stared at me for a second in disbelief, then broke out laughing as they had never heard that particular phrase. It was kind of like hearing “…Bless his heart” for the first time when used following an obvious insult.
In the year 1990 the Power Plant had a program that they called, “We’ve Got the Power”. I will talk more about this in a later post, so I will just say that it was a program where we broke up into teams and tried to find ways to save the company money. But long before “We’ve Got the Power”, there was Sonny Karcher. He was often trying to figure out how we could make electricity cheaper, or even come up with other ways of making a profit.
One day Sonny asked me this, “Kev, your smart because you learn things from all those books at school so tell me this… someone said the other day that diamonds are made out of coal. Is that true?” I told him it was. Then he said, “Well, what if we had one of those big dirt movers full of coal drive over some coal a bunch of times, would we be able to make diamonds?”
Dirt Mover full of coal
I told him that wouldn’t work because it takes a lot more pressure to make a diamond. So, he asked me if it would work if we put some coal on the railroad track and we let an entire train full of coal run over it. Would it make a diamond then? I assured him that even that wouldn’t make a diamond. He accepted it and just said, “Well, it’s too bad since we have that big pile of coal there, we ought to be able to come up with some way of making them into diamonds.
Another time when we were cleaning out the fish baskets at the intake (a job as smelly as it sounds) next to the 4 big intake pumps. These are the pumps that pump around 189,000 gallons of water per minute each. Sonny told me how big those pumps were and how much water they pumped. Then he said, “You know, that entire boiler is there just to make steam to turn the turbine to make electricity. It seems to me that we could just take these four pumps and have them pump water through the turbine and have it turn the turbines, then we wouldn’t need those big boilers. Why don’t we do something like that?” I assured Sonny that we would never be able to make enough electricity to make up for the electricity it took to turn the pumps that were pumping the water. He shook his head and said that it just seemed to him that those pumps could turn that turbine pretty fast.
One day I watched as Sonny watched another Power Plant man walk into the shop with a new type of lunch box. It was an Igloo Little Playmate. Sonny made a comment about how neat this guy’s new lunch box was. It was a new design at the time.
One exactly like this. These were a new kind of lunch box at the time.
Sonny immediately went out and bought one. The next week he came to work with his shiny new Little Playmate lunch box. I admit. I went and bought one myself a few weeks later. But this was the beginning of a trend that I noticed with Sonny. I began to notice that Sonny seemed to pick one item from each of the people he admired, and went and bought one for himself. Or he would pick up a phrase that someone else would say, and would start using that.
At first I thought it might just be a coincidence, so I started to test my hypothesis. When I would see something new that Sonny brought to work, I would look around to see who else had one of those, and sure enough. Someone close by would have one. Then I would hear Sonny talk a certain way. His accent would change and he would say something like he was imitating someone else, and usually I could tell right away who talked like that and knew that Sonny had borrowed that phrase from that person.
Some may think that this would be annoying, but I think with Sonny it was an act of endearment. It was his way of connecting with those people that he admired. Sonny had a small yellow orange Ford truck and I figured that someone else must have a truck like that, so I started looking all around for one like it. It took me a couple of weeks, but one morning while we were carpooling our way to the power plant, we came up behind the same kind of truck that Sonny had on its way to the plant. It was green instead of yellow, but it was undoubtedly the same model of truck. It was owned by Ken Reece, who was the manager over the tool room and warehouse.
Sonny imitated a voice that had me puzzled for a while. I had checked out all the Power Plant Men around trying to figure out who Sonny was imitating. Every once in a while Sonny would change his way of talking when he was making a point where he would let his lower lip come forward and work its way left and right as he talked, and he would close one eye more than the other and talk in a strange sort of a southern drawl. I just knew he was imitating someone because it was so different than just the regular Sonny.
Finally, one day when I was walking through the shop I heard someone in the welding area talking just like Sonny would talk when he used that voice. There was no mistake. That had to be the person. I could hear every inflection in his voice and it had to be the voice that Sonny was imitating because it had been much more honed and refined to give just the right effect. So, I changed the course I was travelling so that I could make my way around to the welders to see who it was that was talking like that.
There in the middle of the welding shop was a heavier set man standing in the middle of a group of welders telling a story. Everyone was listening to him quietly just as if it was story time at the library. So, I stopped and watched. This man wasn’t wearing an Electric Company hard hat. He was wearing a Brown and Root hard hat, which indicated that he worked for the construction company that was building the plant.
This guy was undoubtedly a master storyteller. When it came to the climactic part of the story, the bottom of his mouth would stick out with his lip moving left and right and left again, and one eye was partially closed to show the intensity of the situation and the drawl would intensify. Finally. I had found the man that Sonny Karcher had admired enough to take one of his favorite traits and connect it to himself. I could see why Sonny admired him so much. He had everyone within listening distance captivated by his story.
This Brown and Root hand soon became an employee of the Electric Company within a couple of weeks after I left at the end of the summer (on September 9, 1979). This heavier set person was still working at the plant when I first posted this story last year, but has since retired. He was one of this country’s leading Turbine mechanics and he can still tell a story like no one else. He is no longer as heavy. He is rather thin in comparison. He improved his health after realizing that if he really loved his family, he needed to take better care of himself.
I consider this True Power Plant Man, Ray Eberle, to be a dear friend of mine. I have never met anyone that looked more like my own grandfather than Ray. Not that he was that much older. No. He looked almost exactly like my grandfather looked when he was Ray’s age. There was no nicer man than my dad’s dad, and there is no nicer Power Plant Man than Ray Eberle.
Ray Eberle
Comments from the re-post:
-
The Janitors at Seminole showed me how the PPM (Power Plant Men) were spitting their tobacco juice inside I-beam webs, in tight corners, and other hard to clean spots. They asked me to put out a memo asking the spitters to just spit out in the middle of the floor so they could clean it up much easier, which I did. I can’t remember for sure, but it seems like the puddles of stinky gross slime around the Plant tailed off for a while.
Good story, Kevin. I hadn’t thought about Ray Eberle for a long time. He was a super turbine man I always enjoyed being around. I just remember his competence and his positive attitude.

It’s both amusing, and comforting to know the same things happen at power plants everywhere, we went through a “sunflower seed phase” which plugged the drains & the plant finally came up with a “NO MORE SUNFLOWER SEEDS” rule!
Lifecycle of a Power Plant Lump of Coal
Originally posted August 16, 2013:
Fifty Percent of our electricity is derived from coal. Did you ever wonder what has to take place for that to happen? I thought I would walk through the lifecycle of a piece of coal to give you an idea. I will not start back when the it was still a tree in a prehistoric world where dinosaurs grew long necks to reach the branches. I will begin when the large scoop shovel digs it out of the ground and loads it onto a coal truck.
The coal is loaded onto trucks like these before it is dumped onto the train cars. This photo was found at http://www.gillettechamber.com/events/eventdetail.aspx?EventID=2827
The coal for the power plant in North Central Oklahoma came from Wyoming. There were trains from the Black Thunder Mine and the Powder River Basin.
Coal Trains on their way to power plants
It’s a long ride for the lump of coal sitting in the coal train on it’s way to Oklahoma. Through Nebraska and Kansas. It’s possible for the coal to be visited by a different kind of traveler. One that we may call “A tramp.” Someone that catches a ride on a train without paying for the ticket.
One time a tramp (or a hobo, I don’t remember which), caught a ride on one of our coal trains. They forgot to wake up in time, and found their self following the lumps of coal on their next phase of the journey. You see. Once the coal reached the plant, one car at a time enters a building called the “Rotary Dumper”.
A rotary dumper much like the one that was at our Power Plant
As each train car enters the dumper four clamps come done on the car and it rolls upside down dumping the coal into a bin below. Imagine being a tramp waking up just in time to find yourself falling into a bin full of coal. with a car full of coal dumping coal on top of you. One coal car contained 102 tons of coal (today they carry 130 tons). Today one train contains 13,300 tons of coal. This is over 26 million pounds of coal per train.
Miraculously, this passenger survived the fall and was able to call for help or someone saw him fall. He was quickly rescued and brought to safety. Needless to say, the tramp went from being penniless to being, “comfortable” very quickly. I don’t know that it made the news at the time. I think the electric company didn’t want it to become “viral” that they had dumped a hobo into a coal bin by accident. Well. They didn’t know what “going viral” meant at the time, but I’m sure they had some other phrase for it then.
Ok. Time for a Side Story:
Since I’m on the subject of someone catching a clandestine ride on a train, this is as good of a place as any to sneak in the tragic story of Mark Meeks. Well. I say it was tragic. When Mark told the story, he seemed rather proud of his experience. You see. Mark was a construction electrician. He hired on as a plant electrician in order to settle down, but in his heart I felt like he was always a construction electrician. That is, he didn’t mind moving on from place to place. Doing a job and then moving on.
Mark explained that when he was working at a construction job in Chicago where he worked for 2 years earning a ton of overtime, he figured that by the time he finished he would have saved up enough to buy a house and settle down. He was married and living in an apartment in Chicago. He didn’t spend much time at home as he was working 12 hour days at least 6 days each week. He figured that was ok, because when he was done, he would be set for life.
Unknown to him at the time, each morning when he woke up before the crack of dawn to go to work, his wife would drive to O’Hara airport and catch a plane to Dallas, Texas where she was having an affair with some guy. By the time Mark returned from work 14 hours later, she was back home. Each day, Mark was earning a ton of overtime, and his wife was burning it on airline tickets.
When the two years were over, Mark came home to his apartment to collect his wife and his things and go live in peace in some small town some where. That was when he learned that his wife had been having the affair and using all his money to do it. She was leaving him. Penniless.
Completely broke, Mark drifted around for a while. Finally one day he saw a train that was loaded down with wooden electric poles. Mark figured that wherever those poles were going, there was going to be work. So, he hopped on the train and traveled all the way from Minneapolis Minnesota riding in the cold, wedged between some wooden poles on one of the cars on the train.
The train finally arrived at its destination somewhere at a port in the Gulf of Mexico. I don’t remember if it was Mississippi or Louisiana. He watched as they unloaded the poles, waiting to see what jobs were going to be needed for whatever the poles were for. He watched as they took the large wooden poles and piled them up in the ocean. They were using them to build up the shoreline. There were no jobs.
It is when you have been beaten down to the point of breaking when you reach a very important point in your life. Do you give up, or do you pick yourself up and make something of yourself? Mark chose the latter. He was a natural fighter. He eventually ended up at our plant as contract help, and then was hired as a plant electrician.
End of side story.
Let’s follow the lump of coal after it is poured out of the coal train in the dumper…
The coal is fed onto a conveyor belt. Let’s call this Conveyor 1, (because that is what we called it in the plant). This has a choice to feed it onto belt 2 which leads up to the stack out tower, or it can feed the other way to where some day it was planned to add another conveyor with another stackout tower. This was going to go to a pile of coal for two other units that were never built.
Anyway, when the coal drops down on Conveyor 2, way under ground, it travels up to the ground level, and continues on its way up to the top of the stackout tower where it feeds onto Belt 3. Belt 3 is a short belt that is on an arm that swings out over the coal pile. The coal is fed onto the coal pile close to the stack out tower. I suppose it is called stack out, because the coal is stacked up next to the tower.
A view of the coalyard from the top of the Smoke Stack. The tower with the conveyor running up to the top is the stack out tower. Belt 3 is the arm pointing to the right in this picture
Anyway, there are large dozers (bulldozers) and dirt movers that pickup the coal and spread it out to make room for more coal from more coal trains. As mentioned above. One train now carries 26 million pounds of coal.
Dirt Mover full of coal
the coal that is spread out on the coal pile has to stay packed down otherwise it would spontaneously combust. That is, it would catch on fire all by itself. Once coal on a coal pile catches on fire it is impossible to “reasonably” put out. You can spray all the water on it you want and it won’t go out. When a fire breaks out, you just have to drag the burning coal off of the pile and let it burn out.
In order to keep the coal from performing spontaneous combustion, the dirt movers kept it packed down. As long as the coal is packed tight, air can’t freely reach the buried coal, and it doesn’t catch fire. So, dirt movers were constantly driving back and forth on the coal pile to keep the coal well packed. Even on the picture of the coalyard above from the smoke stack, you can see two pieces of heavy equipment out on the coal pile traveling back and forth packing the coal.
Anyway, the next phase in the life of the lump of coal happens when it finds itself directly under the stack out tower, and it is fed down by a vibratory feeder onto a conveyor. In our plant, these belts were called, Belts 4, 5, 6 and 7. Belts 4 and 5 fed onto Belt 8 and belts 6 and 7 fed onto belt 9.
Belts 8 and 9 brought the coal up from under the coal pile to the top of the Crusher tower. In the picture above you can see that tower to the right of the stack out tower with the long belts coming from the bottom of the tower toward the plant. The crusher tower takes the large lumps of coal that can be the size of a baseball or a softball and crushes it down to the size of marbles and large gumballs.
Coal conveyor carrying coal to the coal silos from the coalyard. This is the size of the coal after it has been crushed by the crusher
From the crusher tower the lump of coal which is now no more than a nugget of coal travels from the coal yard up to the plant on belts 10 and 11.
conveyor 10 and 11 are almost 1/2 mile long
Up at the top of this belt in the distance you can see another tower. This tower is called the Transfer tower. Why? Well, because it transfers the coal to another set of belts, Belt 12 and 13. You can see them going up to the right to that tower in the middle between the two boilers.
The tower between the two boilers is called the Surge Bin tower. That basically means that there is a big bin there that can hold a good amount of coal to feed to either unit. At the bottom of the white part of the tower you can see that there is a section on each side. This is where the tripper galleries are located. There are two belts in each tripper, and two belts that feed to each tripper belt from the surge bin. So, just to keep counting, Belts 14 and 15 feed to unit one and belts 16 and 17 feed to unit 2 from the surge bin. then Belts 18 and 19 are the two tripper belts that dump coal into the 6 silos on unit one, while belts 20 and 21 feed the silos on unit 2.
Once in the Coal silos, the coal is through traveling on belts. The silos are positioned over things called bowl mills. The coal is fed from the silo into the bowl mill through something called a Gravimetric feeder, which is able to feed a specific amount of coal into the bowl mill. This is the point that basically decides how hot the boiler is going to be.
Once the coal leaves the gravimetric feeder and drops down to the bowl mill, it is bound for the boiler. The gravimetric feeder is tied right to the control room. When they need to raise load more than just a minimal amount, a control room operator increases the amount of coal being fed from these feeders in order to increase the flow of coal into the boiler….. I don’t know… maybe it’s more automatic than that now…. The computer probably does it these days.
When the nugget of coal falls into the bowl mill the long journey from the coal mine in Wyoming is almost complete. Its short life as a nugget is over and it is pulverized into powder. The powder is finer than flour. Another name for a bowl mill is “Pulverizer”. The coal comes from the Powder River Basin in Wyoming and just before it is consumed in Oklahoma it really does become powder.
Big rollers are used to crush the coal into fine particles. The pulverized coal is blown up pipes by the primary air fans and blown directly into the boiler where they burst into flames. A bright orange flame. The color reminds me of orange sherbet Ice cream.
The color of the fireball in the boiler
At this point an incredible thing happens to the coal that so many years ago was a part of a tree or some other plant. The chemical process that trapped the carbon from the carbon dioxide millions of years earlier is reversed and the carbon is once again combined to the oxygen as it was many millennium ago. A burst of heat is released which had been trapped after a cooling effect below the tree as it sucked the carbon out of the environment way back then.
The heat is transferred to the boiler tubes that line the boiler. The tubes heat the water and turn it into steam. The steam shoots into the turbine that turns a generator that produces the electricity that enters every house in the country. The solar power from eons ago that allowed the tree to grow is being used today to power our world. What an amazing system.
To take this one step further, the carbon dioxide that is released into the atmosphere today is replenishing the lost carbon dioxide from many years ago. Back when plants could breathe freely. Back before the carbon dioxide level was depleted almost to the point of the extinction of plant life on this planet. Remember, what we look on as a pollutant and a poison, to a plant is a chance to grow. The Sahara desert used to be a thriving forest. Maybe it will be again some day.
So, there is the question of global warming. We humans are so short sighted sometimes. We want to keep everything the same way we found it when we were born. We try desperately to keep animals from becoming extinct. We don’t think about the bazillions (ok, so I exaggerate) of animals that were extinct long before man arrived. It is natural for extinction to occur. That is how things evolve. We are trying to keep a system the same when it has always been changing.
Years from now we may develop ways to harness the energy from the sun or even from the universe in ways that are unimaginable today. When that time arrives, let’s just hope that we remain good stewards of the world so that we are around to see it. I believe that the use of fossil fuels, (as odd as that may seem) is a major step in reviving our planet’s natural resources.

Glad Mark fought the good fight, still a sad story.

Great read. I love knowing how things work. As I read the sad story of the traveling electrician, I kept wondering if she could have pulled that off in today’s world of air travel.
when I went to the Christian College in Eugene Oregon, they forced me to take a course in biology at the University of Oregon. I willingly sat and listened to the mix of science and evolution. I admit their perspective was intriguing.
at the end of the class, the last day, the instructor asked each one of her students to tell how the class had affected their thinking.
each one gave the politically correct answer in a variety of form. all the while I sat joyfully waiting my turn.
my response hushed the class for a moment. (it’s been some decades ago so I have to paraphrase but let it be sufficient) “I’m impressed with all the material you’ve covered. it’s astounding to think of all the things that were. but for me this class has only glorified my God. because I realize that in his wisdom he created gasoline for my car.”
you’ve covered a lot of material in your post. and I’m impressed at your diligence to complete it. I thank God for His faithfulness that he has put into you. may He prosper your testimony for the glory of His Holy Son.

We processed several hobo’s through our coal system, & injured a few, but none ever got anything from the power company. I remember we would always worried about finding a chunk of scalp or something in the grating where the tripper car drops coal down into the silo. One especially memorable event was when a coal yard operator found a down vest jacket on the coal pile and bragged about how lucky he was to find this jacket, the size even fit, but the jacket did smell a little funny. yes it was ripped off the body of a hobo by the plow above conveyor one & shot out onto the coal pile by the stackout conveyor.
It was always unnerving to have a pull cord go down in the middle of the night deep down in the coal trestle, while the belts were shut down. You’d have to go down there alone, in the dark & reset the pull cords, so the belts could be started later when needed. You knew it wasn’t a trick because the whole crew had been up in the control room together eating dinner or something. You always wondered if you might run into a real hobo – or the ghost of one.
When Power Plant Durability and Automation Goes Too Far
Everyone expects when they enter an elevator and push a button for the 3rd floor that when the doors open they will find themselves on the third floor. It doesn’t occur to most people what actually has to happen behind the scenes for the elevator to go through the motions of carrying someone up three stories. In most cases you want an automated system that requires as little interaction as possible.
I have found while working in the Coal-fired Power Plant in North Central Oklahoma that some systems are better off with a little less than perfect automation. We might think about that as we move into a new era of automated cars, robot soldiers and automatic government shutdowns. Let me give you a for instance.
The coal trains that brought the coal from Wyoming all the way down to the plant would enter a building called “The Dumper.” Even though this sounds like a less savory place to park your locomotive, it wasn’t called a Dumper because it was a dump. It was called a Dumper because it “Dumped.” Here is a picture of a dumper:
A rotary dumper much like the one that was at our Power Plant
The coal train would pull into this room one car at a time. I talked about the dumper in an earlier post entitled “Lifecycle of a Power Plant Lump of coal“. As each car is pulled into this building by a large clamp called the “Positioner” (How is that for a name? It is amazing how when finding names for this particular equipment they decided to go with the “practical” words. The Positioner positions the coal cars precisely in the right position so that after the car clamps come down on the car, it can be rotated upside down “Dumping” the coal into the hoppers below. No fancy names like other parts of the power Plant like the “Tripper Gallery” or the “Generator Bathtub” here.
A typical coal train has 110 cars full of coal when it enters the dumper. In the picture of the dumper above if you look in the upper left corner you will see some windows. This is the Dumper Control Room. This is where someone sits as each car pulls through the dumper and dumps the coal.
Not long after the plant was up and running the entire operation of the dumper was automated. That meant that once put into motion, the dumper and the controls would begin dumping cars and continue operating automatically until the last car was through the dumper.
Let me try to remember the sequence. I know I’ll leave something out because there are a number of steps and it has been a while since I have been so fortunate as to work on the dumper during a malfunction… But here goes…
I remember that the first coal car on the train had to positioned without the positioner because… well….. the car directly in front of the first car is, of course, the locomotive. Usually a Burlington Northern Santa Fe Engine.
A picture from Shutterstock of a locomotive pulling a coal train
Before I explain the process, let me show you a picture of the Positioner. This the machine that pulls the train forward:
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
The automation begins after the first or second car is dumped. I’ll start with the second car just finishing the process as it rolls back up right after dumping the coal… The car clamps go up.
- The rear holding arm (that holds the car in place from the entrance side of the dumper) lifts up out of the way.
- The Positioner begins pulling the entire train forward.
- Electric eyes on both end of the dumper detect when the next car has entered the dumper.
- The Positioner adjusts the position of the coal car to the exact position (within an inch or two) by backing up and pulling forward a couple of times.
- The Holding arm on the back end comes down on the couplings between the two train cars one back from the car that is going to be dumped.
- The four car clamps come down on the train car at the same time that the dumper begins rotating.
- The Positioner clamp lifts off of the train car couplings.
- Water Sprayers come on that are attached to the top of the dumper so that it wets the coal in order to act as a dust suppression.
- The Positioner travels back to the car clamp between the car that was just emptied before and the car in front of it.
- As the train car rotates to the desired angle. (I think it’s about 145 degrees), it begins slowing down.
- When the car has been rotated as far as desired it comes to a stop.
- The Dumper pauses for a few seconds as all the coal is dumped from the coal car.
- The Positioner moves back and forth until it is in just the right position for the positioner arm to lower onto the couplings between the cars.
- The Sprayers turn off.
- The Dumper begins returning to an upright position.
- The Positioner arm lowers down onto the clamps between the coal cars.
- Once the car is upright the dumper stops rotating.
- The 4 car clamps go up.
- The Holding arm goes up. And the process is repeated.
This is a beautiful process when it works correctly. Before I tell you about the times it doesn’t work correctly, let me tell you about how this process was a little…uh… too automated…
So. The way this worked originally, was that once the automated process was put into operation after the second car had been dumped, all the dumper control room operator had to do was sit there and look out the window at the coal cars being dumped. They may have had some paperwork they were supposed to be doing, like writing down the car numbers as they pulled through the dumper. It seems that paperwork was pretty important back then.
Each car would pull through the dumper… The coal would be dumped. The next car would be pulled in… etc.
Well. Trains come from Wyoming at any time of the day. Train operators were paid pretty well, and the locomotive engineers would come and sit in the control room while the train was being dumped. Often (more often than not it seemed) the trains would pull into the dumper in the middle of the night. Coalyard operators were on duty 24 by 7.
So, imagine this…. Imagine Walt Oswalt… a feisty sandy haired Irishman at the dumper controls around 3 in the morning watching 110 cars pull through the dumper. Dumping coal…. One after the other. I think the time it took to go from dumping one car to the next was about 2 1/2 minutes. So it took about 3 1/2 hours to dump one train (I may be way off on the time… Maybe one of the operators would like to leave a comment below with the exact time).
This meant that the dumper operator had to sit there and watch the coal cars being slowly pulled through the dumper for about 3 hours. Often in the middle of the night.
For anyone who is older than 25 years, you will remember that the last car on a train was called a Caboose. The locomotive engineers called it a “Weight Car”. This made me think that it was heavy. I don’t know. It didn’t look all that heavy to me… You decide for yourself:
A Caboose
Back in those days, there was a caboose on the back of every train. A person used to sit in there while the train was going down the tracks. I think it was in case the back part of the train accidentally became disconnected from the front of the train, someone would be back there to notice. That’s my guess. Anyway. Later on, a sensor was placed on the last car instead of a caboose. That’s why you don’t see them today. Or maybe it was because of something that happened one night…
You see… it isn’t easy for Walt Oswalt (I don’t mean to imply that it was Walt that was there that night.. well… it sounds like I’m implying that doesn’t it…. I use Walt when telling this story because he wouldn’t mind. I really don’t remember who it was) to keep his eyes open and attentive for 3 straight hours. Anyway… One night while the coal cars were going through the dumper automatically being dumped one by one… there was a point when the sprayers stopped spraying and the 4 car clamps rose, and there there was a moment of pause, if someone had been there to listen very carefully, they might have heard a faint snoring sound coming from the dumper control room.
That is all fine and dandy until the final car rolled into the dumper. You see… One night…. while all the creatures were sleeping (even a mouse)… the car clamps came down on the caboose. Normally the car clamps had to be raised to a higher position to keep them from tearing the top section off of the caboose.
If it had been Walt… He woke when he heard the crunching sound of the top of the caboose just in time to see the caboose as it swung upside down. He was a little too late hitting the emergency stop button. The caboose rolled over. Paused for a moment as the person manning the caboose came to a rest on the ceiling inside… then rolled back upright all dripping wet from the sprayer that had meant to keep down the dust.
As the car clamps came up… a man darted out the back of the caboose. He ran out of the dumper…. knelt down… kissed the ground… and decided from that moment on that he was going to start going back to church every Sunday. Ok. I exaggerate a little. He really limped out of the dumper.
Needless to say. A decision had to be made. It was decided that there can be too much automation at times. The relay logic was adjusted so that at the critical point where the dumper decides to dump a coal car, it had to pause and wait until the control room operator toggled the “Dump” switch on the control panel. This meant that the operator had to actively decide to dump each car.
As a software programmer…. I would have come up with another solution… such as a caboose detector…. But given the power that was being exerted when each car was being dumped it was probably a good idea that you guaranteed that the dumper control room operator actually had his eyeballs pointed toward the car being dumped instead of rolled back in his head.
I leave you with that thought as I go to another story. I will wait until another time to talk about all the times I was called out at night when the dumper had failed to function.
This is a short story of durability…
I walked in the electric shop one day as an electrician trainee in 1984 to find that Andy Tubbs had taken an old drill and hooked it up to the 480 volt power source that we used to test motors. Ok. This was an odd site. We had a three phase switch on the wall with a fairly large cable attached with three large clips so we could hook them up to motors that we had overhauled to test the amperage that they pulled to make sure they were within the specified amount according to their nameplate.
I hesitated a moment, but I couldn’t resist…. I had to ask, “Andy…. Why have you hooked up that old drill to 480? (it was a 120 volt drill). He replied matter-of-factly (Factly? Can I really say that in public?), “I am going to burn up this old drill from the Osage Plant (See “Pioneers of Power Plant Fame Finally Find Peace” for more information about Osage Plant) so that I can turn it in for a new one.
Ok. I figured there must be a policy somewhere that said that if you turned in a burned up tool they would give you a new one. I knew that Bud Schoonover down at the toolroom was always particular about how he passed out new tools (I have experienced the same thing at my new job when trying to obtain a new security cable for my laptop).
Anyway. Andy turned the 480 volts on and powered up the drill. The drill began whining as it whirled wildly. Andy stood there holding up the drill as it ran in turbo mode for about five minutes. The drill performed like a champ.
Old Power Drill
After showing no signs of burning itself up running on 480 volts instead of 120 volts, Andy let off of the trigger and set it back on the workbench. He said, “This is one tough drill! I think I’ll keep it.” Sure. It looked like something from the 1950’s (and it probably was). But, as Andy said, it was one tough drill. On that day, because of the extra Durability of that old Pioneer Power Plant Drill, Andy was robbed of a new variable speed, reversible drill that he was so craving.

Great stories!
Coal trains today have engines at the rear of the train. I hope we never try to dump one of them!
It takes about 7 hrs to dump 150 car train
Wasn’t Walt but a certain marine we won’t mention. They dumped the last car & forgot to put the car clamps in the up maximum position. They give the go ahead for the train to pull the caboose through! Instant convertible caboose! Now there are break away clamps on the north side. And there are locomotives on the rear of the train because the trains are made up of 150 cars .
Like you, I can think of several ways to automate the process without dumping the caboose but I think the operator pushing the button may be the best. Automation can get out of hand.
An engineer used to remind us: “A machine always does what you tell it to…whethr you want it to, or not.”
IF the union or the lawyers require a duty operator on an automated process, I’m all for giving him a button to push and attaching some responsibility. All automation designs are approved by Murphy…Wow! Thanks for the update Bruce!
Power Plant Spider in the Eye
If you have been following my posts for very long, you may have the idea that I just like to write posts about spiders. After writing two posts about Spider Wars (see posts: “Power Plant Spider Wars and Bugs in the Basement” and “Power Plant Spider Wars II – The Phantom Menace“), another post about spiders just seems like a bit much. Even though there is a spider in this story, another appropriate title could be something like “Another night in the Life of a Power Plant Electrician”. Without further ado, here is the story.
Ninety nine times out of a hundred, when the phone rang in the middle of the night, it was the Power Plant in North Central Oklahoma calling. I don’t remember a time when the Shift Supervisor on the other end of the phone wasn’t very polite. They knew they were waking someone from their sleep to ask them to drive 30 miles out to the plant in the wee hours of the morning.
The Shift Supervisor, whether it was Joe Gallahar, Jim Padgett, Jack Maloy, or Gary Wright, they would all start out with something like, “Hey, sorry to wake you buddy…”. After such an apologetic introduction, how could you be upset that your sleep had just been interrupted? Then they would proceed to tell you why they needed your assistance. For me, it was usually because the coal dumper had stopped working while a train was dumping their coal. This meant that 110 cars tied to three or four engines was sitting idle unable to move.
Each car on the train would be dumped one at a time as it was pulled through the rotary dumper. The process was automated so that the operator in the control room watching out of the window only had to push one switch to dump each car.
A rotary dumper much like the one that was at our Power Plant
The train would move forward to the next car automatically as a large arm on a machine called a Positioner would come down on the coupling between the cars and pull the entire train forward to the next car.
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
There were so many moving parts involved in positioning the car in place and rolling it over to dump the coal, that it was common for something to go wrong. When that happened the entire process would come to a halt and the train would just have to sit there until someone came to fix it. That was usually an electrician since the dumper and the positioner was all controlled by relays much like the elevator controls, only more complicated.
This particular night, Joe Gallahar had called me. It seemed that there was an intermittent problem with the dumper that didn’t seem to make much sense and they couldn’t figure out why it was acting so strange. One of the train cars had actually been damaged as the positioner arm would start coming up from the coupling to the point where the holding arm on the other end of the dumper had come up, then the positioner arm began going back down, causing the train to move on it’s own only to have the arm on the positioner scrape the side of the train car as it rolled backward uncontrolled.
Though it was less frequent, it was not so strange to have a train damaged by erratic dumper controls. I have seen the side of a train car smashed in by the positioner arm when it decided to inappropriately come down. This night, the problem was acting like that. So, instead of damaging the train further, they decided to call me out to have a look at it.
I always had the philosophy when being called out in the middle of the night to be just as polite back to the Shift Supervisor when I answered the phone. I had a Marketing professor at Oklahoma State University named Dr. Lee Manzer, who explained this one day.
Here is a short side story about Dr. Manzer —
Dr. Manzer told a story in class one day about how he was travelling home one day from a long and difficult trip where everything had gone wrong. It was very late at night when he arrived at his house (which, incidentally was just down the street from my parent’s house), he was really beat. He went into his bedroom and began preparing for bed.
About the time he was taking off his tie, his wife rolled over in bed and welcomed him home. Then she said, “Oh, by the way. I forgot to buy milk (or maybe it was ice cream). Do you think you could run down to the store and buy some?”
Dr. Manzer explained his decision making process at that point like this: “I could either go on a rant and tell my wife what a long and tiring day I had just had and now you are asking me to go buy milk? , and then I would go get the milk. Or I could say, ‘Of course Dear. I would be glad to go buy some milk.’ Either way, I was going to go buy the milk. So, I could do it one of two ways. I could complain about it or I could be positive. I could either score points or lose them…. hmm…. Let’s see…. what did I do? I said, ‘Of course Dear.'”
— End of the side story about Dr. Lee Manzer who by the way was a terrific Marketing Professor. I understand he still teaches to this day.
So, when Joe Gallahar called me that night, and explained that the dumper was acting all erratic, Instead of saying “Yes Dear.” as that wouldn’t have been appropriate, I told him, “No problem. I’ll be there as soon as I can.” My wife Kelly knew who was on the other end of the phone when she heard my answer. She had heard it many times before. I usually only had to say one word after hanging up the phone, “Dumper”, and she knew what that meant.
A Power Plant Electrician’s spouse knows that this is part of the job. As I pulled on the jeans that I had laid out before I went to bed, Kelly would usually say something in her sleep like, “Be careful”. I would give her a hug and tell her I’ll be back in a while, even though, sometimes I would be gone for two days working on the precipitator during a start up or some major catastrophe. Usually, it was just a couple of hours before I came crawling back in bed.
This particular night I drove to work in silence with the window open so that the cool air would keep me awake. Normally I had the radio on some rock station so that I would be singing along (in my terribly off-key singing voice) in order to stay awake. Sometimes I would just take the 25 minutes of silence to just think.
My thought that night was that it was nice to be wanted. There is some comfort in knowing that the Shift Supervisor could call me with enough confidence to know that I would be able to come out on my own and fix a problem that was costing the company a large amount of money each hour the dumper was offline. Some might think that I would be annoyed to be wakened in the middle of the night to go fix something at the plant. That night, as most nights I was feeling honored.
That wasn’t always the case, and I’ll soon write a post about another call out in the middle of the night where Scott Hubbard and I wondered exactly why they called us… but that’s another story.
When I arrived at the plant, I rolled my car up to the speaker at the front gate and said, “Hello” with an arrogant English accent. I don’t know why, but I always liked doing that. I think it was Billy Epperson who answered back. I told him I was here to work on the dumper. He thanked me and opened the gate and I drove the 1/2 mile down the hill to the plant parking lot. As I went over the hill, in the moonlight I could see the train up at the coal yard looking like a long silver snake.
I walked into the maintenance shop and grabbed a truck key off of the hook and drove around to the electric shop to pick up my hard hat and tool bucket.
This is an actual picture of my tool bucket
I took the long way around to the coal yard since the train blocked the shortest route. We had a tunnel on the west end of the coal yard that went under the tracks for just this occasion.
When I arrived at the dumper, Stanley Robbins explained that he had tried troubleshooting this problem himself, but he couldn’t find anything that would explain the strange behavior. Since the last downsizing, we were all able to sort of mix our skills so that an operator could do simple electric tasks if they felt comfortable with it. Stanley knew enough to fix your normal minor dumper issues. This one was a little different.
Since I had been an electrician for the past 15 years at this point, I felt pretty confident that I would quickly find the problem and be heading back home soon. So, I walked into the dumper switchgear where the dumper controls are found. I asked Stanley to go turn on the power to the dumper so that I could watch the relays. When the power was on, I began tracing the circuits looking for the point of failure.
The problem was intermittent, and when Stanley started the dumper back up, everything seemed to be working just fine. Stanley explained that this was why they couldn’t use the dumper because they couldn’t be sure when it was going to malfunction. They had even uncoupled the train and pulled it apart right where the positioner arm was so that I could see what was happening.
Using radios (walkie talkies), I asked Stanley to move the positioner arm up and down while I checked it. He lowered it and raised it back up without any problem. When he began lowering it the second time, it suddenly stopped halfway down. Watching the controls, I could see that it indicated that it had come all the way down. It would be this case that would tell the holding arm on the far side of the dumper to go back up, which is what happened when the train rolled back earlier that night.
Then the relays rattled like they were picking up and dropping out rapidly. Then the problem cleared up again. Somehow the positioner arm had thought it had come down on the car clamps when it was still up in the air. That was not likely to happen because when something fails it usually doesn’t see what it’s supposed to see, not the other way around. It doesn’t usually see something that isn’t there.
So, I had Stanley lower the positioner arm down so that it was level with the ground, so that I could check the connections to the electric eye that was on the positioner clamp that detected the train car clamp when it came down. I couldn’t find any lose connections or anything that would explain it.
So I told Stanley that I was going to look up from under the car clamp to look at the electric eye. So, I asked him to kill the power to the positioner so that it wouldn’t move while I was doing that and crush me like a bug. Kneeling on the train track, I took my flashlight and looked up at the electric eye from under the car clamp, and this is what I saw:
A spider almost like this
This spider had built a spider web in front of the electric eye on the positioner and was sitting right in the middle causing the positioner to think it was down on the car clamp when it wasn’t. Stanley was watching me from the window of the dumper control room when he saw me stand up quickly and look up at him with a big grin on my face. I gave him a thumbs up.
You know the phrase, “Everyone has 10 minutes of fame….” It indicates that some time in most people’s lives they are famous for a brief moment. It may or may not define the rest of their life. Well. This was that spiders claim to fame. This one spider had successfully stranded a coal train with 110 cars of coal. A train crew, a coal yard operator, and one lone electrician that had traveled 30 miles to watch it act out it’s drama of catching gnats on it’s web being constantly watched by one large electric eye.
I did not drive home in silence that early morning. I laughed out loud all the way home. I still laugh to myself to this day when I think about this night. Phrases like, “Isn’t life wonderful” comes to my mind. Or “Even Spiders desire attention every now and then.” Could there have been a better malfunction than to have a spider dancing in front of an electric eye out in the plains of Oklahoma saying, “Look at me! Look at me!” and by golly. Someone did! I’m just glad it was me.
When Power Plant Durability and Automation Goes Too Far
Everyone expects when they enter an elevator and push a button for the 3rd floor that when the doors open they will find themselves on the third floor. It doesn’t occur to most people what actually has to happen behind the scenes for the elevator to go through the motions of carrying someone up three stories. In most cases you want an automated system that requires as little interaction as possible.
I have found while working in the Coal-fired Power Plant in North Central Oklahoma that some systems are better off with a little less than perfect automation. We might think about that as we move into a new era of automated cars, robot soldiers and automatic government shutdowns. Let me give you a for instance.
The coal trains that brought the coal from Wyoming all the way down to the plant would enter a building called “The Dumper.” Even though this sounds like a less savory place to park your locomotive, it wasn’t called a Dumper because it was a dump. It was called a Dumper because it “Dumped.” Here is a picture of a dumper:
A rotary dumper much like the one that was at our Power Plant
The coal train would pull into this room one car at a time. I talked about the dumper in an earlier post entitled “Lifecycle of a Power Plant Lump of coal“. As each car is pulled into this building by a large clamp called the “Positioner” (How is that for a name? It is amazing how when finding names for this particular equipment they decided to go with the “practical” words. The Positioner positions the coal cars precisely in the right position so that after the car clamps come down on the car, it can be rotated upside down “Dumping” the coal into the hoppers below. No fancy names like other parts of the power Plant like the “Tripper Gallery” or the “Generator Bathtub” here.
A typical coal train has 110 cars full of coal when it enters the dumper. In the picture of the dumper above if you look in the upper left corner you will see some windows. This is the Dumper Control Room. This is where someone sits as each car pulls through the dumper and dumps the coal.
Not long after the plant was up and running the entire operation of the dumper was automated. That meant that once put into motion, the dumper and the controls would begin dumping cars and continue operating automatically until the last car was through the dumper.
Let me try to remember the sequence. I know I’ll leave something out because there are a number of steps and it has been a while since I have been so fortunate as to work on the dumper during a malfunction… But here goes…
I remember that the first coal car on the train had to positioned without the positioner because… well….. the car directly in front of the first car is, of course, the locomotive. Usually a Burlington Northern Santa Fe Engine.
A picture from Shutterstock of a locomotive pulling a coal train
Before I explain the process, let me show you a picture of the Positioner. This the machine that pulls the train forward:
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
The automation begins after the first or second car is dumped. I’ll start with the second car just finishing the process as it rolls back up right after dumping the coal… The car clamps go up.
- The rear holding arm (that holds the car in place from the entrance side of the dumper) lifts up out of the way.
- The Positioner begins pulling the entire train forward.
- Electric eyes on both end of the dumper detect when the next car has entered the dumper.
- The Positioner adjusts the position of the coal car to the exact position (within an inch or two) by backing up and pulling forward a couple of times.
- The Holding arm on the back end comes down on the couplings between the two train cars one back from the car that is going to be dumped.
- The four car clamps come down on the train car at the same time that the dumper begins rotating.
- The Positioner clamp lifts off of the train car couplings.
- Water Sprayers come on that are attached to the top of the dumper so that it wets the coal in order to act as a dust suppression.
- The Positioner travels back to the car clamp between the car that was just emptied before and the car in front of it.
- As the train car rotates to the desired angle. (I think it’s about 145 degrees), it begins slowing down.
- When the car has been rotated as far as desired it comes to a stop.
- The Dumper pauses for a few seconds as all the coal is dumped from the coal car.
- The Positioner moves back and forth until it is in just the right position for the positioner arm to lower onto the couplings between the cars.
- The Sprayers turn off.
- The Dumper begins returning to an upright position.
- The Positioner arm lowers down onto the clamps between the coal cars.
- Once the car is upright the dumper stops rotating.
- The 4 car clamps go up.
- The Holding arm goes up. And the process is repeated.
This is a beautiful process when it works correctly. Before I tell you about the times it doesn’t work correctly, let me tell you about how this process was a little…uh… too automated…
So. The way this worked originally, was that once the automated process was put into operation after the second car had been dumped, all the dumper control room operator had to do was sit there and look out the window at the coal cars being dumped. They may have had some paperwork they were supposed to be doing, like writing down the car numbers as they pulled through the dumper. It seems that paperwork was pretty important back then.
Each car would pull through the dumper… The coal would be dumped. The next car would be pulled in… etc.
Well. Trains come from Wyoming at any time of the day. Train operators were paid pretty well, and the locomotive engineers would come and sit in the control room while the train was being dumped. Often (more often than not it seemed) the trains would pull into the dumper in the middle of the night. Coalyard operators were on duty 24 by 7.
So, imagine this…. Imagine Walt Oswalt… a feisty sandy haired Irishman at the dumper controls around 3 in the morning watching 110 cars pull through the dumper. Dumping coal…. One after the other. I think the time it took to go from dumping one car to the next was about 2 1/2 minutes. So it took about 3 1/2 hours to dump one train (I may be way off on the time… Maybe one of the operators would like to leave a comment below with the exact time).
This meant that the dumper operator had to sit there and watch the coal cars being slowly pulled through the dumper for about 3 hours. Often in the middle of the night.
For anyone who is older than 25 years, you will remember that the last car on a train was called a Caboose. The locomotive engineers called it a “Weight Car”. This made me think that it was heavy. I don’t know. It didn’t look all that heavy to me… You decide for yourself:
A Caboose
Back in those days, there was a caboose on the back of every train. A person used to sit in there while the train was going down the tracks. I think it was in case the back part of the train accidentally became disconnected from the front of the train, someone would be back there to notice. That’s my guess. Anyway. Later on, a sensor was placed on the last car instead of a caboose. That’s why you don’t see them today. Or maybe it was because of something that happened one night…
You see… it isn’t easy for Walt Oswalt (I don’t mean to imply that it was Walt that was there that night.. well… it sounds like I’m implying that doesn’t it…. I use Walt when telling this story because he wouldn’t mind. I really don’t remember who it was) to keep his eyes open and attentive for 3 straight hours. Anyway… One night while the coal cars were going through the dumper automatically being dumped one by one… there was a point when the sprayers stopped spraying and the 4 car clamps rose, and there there was a moment of pause, if someone had been there to listen very carefully, they might have heard a faint snoring sound coming from the dumper control room.
That is all fine and dandy until the final car rolled into the dumper. You see… One night…. while all the creatures were sleeping (not even a mouse)… the car clamps came down on the caboose. Normally the car clamps had to be raised to a higher position to keep them from tearing the top section off of the caboose.
If it had been Walt… He woke when he heard the crunching sound of the top of the caboose just in time to see the caboose as it swung upside down. He was a little too late hitting the emergency stop button. The caboose rolled over. Paused for a moment as the person manning the caboose came to a rest on the ceiling inside… then rolled back upright all dripping wet from the sprayer that had meant to keep down the dust.
As the car clamps came up… a man darted out the back of the caboose. He ran out of the dumper…. knelt down… kissed the ground… and decided from that moment on that he was going to start going back to church every Sunday. Ok. I exaggerate a little. He really limped out of the dumper.
Needless to say. A decision had to be made. It was decided that there can be too much automation at times. The relay logic was adjusted so that at the critical point where the dumper decides to dump a coal car, it had to pause and wait until the control room operator toggled the “Dump” switch on the control panel. This meant that the operator had to actively decide to dump each car.
As a software programmer…. I would have come up with another solution… such as a caboose detector…. But given the power that was being exerted when each car was being dumped it was probably a good idea that you guaranteed that the dumper control room operator actually had his eyeballs pointed toward the car being dumped instead of rolled back in his head.
I leave you with that thought as I go to another story. I will wait until another time to talk about all the times I was called out at night when the dumper had failed to function.
This is a short story of durability…
I walked in the electric shop one day as an electrician trainee in 1984 to find that Andy Tubbs had taken an old drill and hooked it up to the 480 volt power source that we used to test motors. Ok. This was an odd site. We had a three phase switch on the wall with a fairly large cable attached with three large clips so we could hook them up to motors that we had overhauled to test the amperage that they pulled to make sure they were within the specified amount according to their nameplate.
I hesitated a moment, but I couldn’t resist…. I had to ask, “Andy…. Why have you hooked up that old drill to 480? (it was a 120 volt drill). He replied matter-of-factly (Factly? Can I really say that in public?), “I am going to burn up this old drill from the Osage Plant (See “Pioneers of Power Plant Fame Finally Find Peace” for more information about Osage Plant) so that I can turn it in for a new one.
Ok. I figured there must be a policy somewhere that said that if you turned in a burned up tool they would give you a new one. I knew that Bud Schoonover down at the toolroom was always particular about how he passed out new tools (I have experienced the same thing at my new job when trying to obtain a new security cable for my laptop).
Anyway. Andy turned the 480 volts on and powered up the drill. The drill began whining as it whirled wildly. Andy stood there holding up the drill as it ran in turbo mode for about five minutes. The drill performed like a champ.
Old Power Drill
After showing no signs of burning itself up running on 480 volts instead of 120 volts, Andy let off of the trigger and set it back on the workbench. He said, “This is one tough drill! I think I’ll keep it.” Sure. It looked like something from the 1950’s (and it probably was). But, as Andy said, it was one tough drill. On that day, because of the extra Durability of that old Pioneer Power Plant Drill, Andy was robbed of a new variable speed, reversible drill that he was so craving.

Comments from original post:
Great stories!
Coal trains today have engines at the rear of the train. I hope we never try to dump one of them!
It takes about 7 hrs to dump 150 car train
Wasn’t Walt but a certain marine we won’t mention. They dumped the last car & forgot to put the car clamps in the up maximum position. They give the go ahead for the train to pull the caboose through! Instant convertible caboose! Now there are break away clamps on the north side. And there are locomotives on the rear of the train because the trains are made up of 150 cars .
Like you, I can think of several ways to automate the process without dumping the caboose but I think the operator pushing the button may be the best. Automation can get out of hand.
An engineer used to remind us: “A machine always does what you tell it to…whethr you want it to, or not.”
IF the union or the lawyers require a duty operator on an automated process, I’m all for giving him a button to push and attaching some responsibility. All automation designs are approved by Murphy…Wow! Thanks for the update Bruce!
Lifecycle of a Power Plant Lump of Coal
Originally posted August 16, 2013:
Fifty Percent of our electricity is derived from coal. Did you ever wonder what has to take place for that to happen? I thought I would walk through the lifecycle of a piece of coal to give you an idea. I will not start back when the it was still a tree in a prehistoric world where dinosaurs grew long necks to reach the branches. I will begin when the large scoop shovel digs it out of the ground and loads it onto a coal truck.
The coal is loaded onto trucks like these before it is dumped onto the train cars. This photo was found at http://www.gillettechamber.com/events/eventdetail.aspx?EventID=2827
The coal for the power plant in North Central Oklahoma came from Wyoming. There were trains from the Black Thunder Mine and the Powder River Basin.
Coal Trains on their way to power plants
It’s a long ride for the lump of coal sitting in the coal train on it’s way to Oklahoma. Through Nebraska and Kansas. It’s possible for the coal to be visited by a different kind of traveler. One that we may call “A tramp.” Someone that catches a ride on a train without paying for the ticket.
One time a tramp (or a hobo, I don’t remember which), caught a ride on one of our coal trains. They forgot to wake up in time, and found their self following the lumps of coal on their next phase of the journey. You see. Once the coal reached the plant, one car at a time enters a building called the “Rotary Dumper”.
A rotary dumper much like the one that was at our Power Plant
As each train car enters the dumper four clamps come done on the car and it rolls upside down dumping the coal into a bin below. Imagine being a tramp waking up just in time to find yourself falling into a bin full of coal. with a car full of coal dumping coal on top of you. One coal car contained 102 tons of coal (today they carry 130 tons). Today one train contains 13,300 tons of coal. This is over 26 million pounds of coal per train.
Miraculously, this passenger survived the fall and was able to call for help or someone saw him fall. He was quickly rescued and brought to safety. Needless to say, the tramp went from being penniless to being, “comfortable” very quickly. I don’t know that it made the news at the time. I think the electric company didn’t want it to become “viral” that they had dumped a hobo into a coal bin by accident. Well. They didn’t know what “going viral” meant at the time, but I’m sure they had some other phrase for it then.
Ok. Time for a Side Story:
Since I’m on the subject of someone catching a clandestine ride on a train, this is as good of a place as any to sneak in the tragic story of Mark Meeks. Well. I say it was tragic. When Mark told the story, he seemed rather proud of his experience. You see. Mark was a construction electrician. He hired on as a plant electrician in order to settle down, but in his heart I felt like he was always a construction electrician. That is, he didn’t mind moving on from place to place. Doing a job and then moving on.
Mark explained that when he was working at a construction job in Chicago where he worked for 2 years earning a ton of overtime, he figured that by the time he finished he would have saved up enough to buy a house and settle down. He was married and living in an apartment in Chicago. He didn’t spend much time at home as he was working 12 hour days at least 6 days each week. He figured that was ok, because when he was done, he would be set for life.
Unknown to him at the time, each morning when he woke up before the crack of dawn to go to work, his wife would drive to O’Hara airport and catch a plane to Dallas, Texas where she was having an affair with some guy. By the time Mark returned from work 14 hours later, she was back home. Each day, Mark was earning a ton of overtime, and his wife was burning it on airline tickets.
When the two years were over, Mark came home to his apartment to collect his wife and his things and go live in peace in some small town some where. That was when he learned that his wife had been having the affair and using all his money to do it. She was leaving him. Penniless.
Completely broke, Mark drifted around for a while. Finally one day he saw a train that was loaded down with wooden electric poles. Mark figured that wherever those poles were going, there was going to be work. So, he hopped on the train and traveled all the way from Minneapolis Minnesota riding in the cold, wedged between some wooden poles on one of the cars on the train.
The train finally arrived at its destination somewhere at a port in the Gulf of Mexico. I don’t remember if it was Mississippi or Louisiana. He watched as they unloaded the poles, waiting to see what jobs were going to be needed for whatever the poles were for. He watched as they took the large wooden poles and piled them up in the ocean. They were using them to build up the shoreline. There were no jobs.
It is when you have been beaten down to the point of breaking when you reach a very important point in your life. Do you give up, or do you pick yourself up and make something of yourself? Mark chose the latter. He was a natural fighter. He eventually ended up at our plant as contract help, and then was hired as a plant electrician.
End of side story.
Let’s follow the lump of coal after it is poured out of the coal train in the dumper…
The coal is fed onto a conveyor belt. Let’s call this Conveyor 1, (because that is what we called it in the plant). This has a choice to feed it onto belt 2 which leads up to the stack out tower, or it can feed the other way to where some day it was planned to add another conveyor with another stackout tower. This was going to go to a pile of coal for two other units that were never built.
Anyway, when the coal drops down on Conveyor 2, way under ground, it travels up to the ground level, and continues on its way up to the top of the stackout tower where it feeds onto Belt 3. Belt 3 is a short belt that is on an arm that swings out over the coal pile. The coal is fed onto the coal pile close to the stack out tower. I suppose it is called stack out, because the coal is stacked up next to the tower.
A view of the coalyard from the top of the Smoke Stack. The tower with the conveyor running up to the top is the stack out tower. Belt 3 is the arm pointing to the right in this picture
Anyway, there are large dozers (bulldozers) and dirt movers that pickup the coal and spread it out to make room for more coal from more coal trains. As mentioned above. One train now carries 26 million pounds of coal.
Dirt Mover full of coal
the coal that is spread out on the coal pile has to stay packed down otherwise it would spontaneously combust. That is, it would catch on fire all by itself. Once coal on a coal pile catches on fire it is impossible to “reasonably” put out. You can spray all the water on it you want and it won’t go out. When a fire breaks out, you just have to drag the burning coal off of the pile and let it burn out.
In order to keep the coal from performing spontaneous combustion, the dirt movers kept it packed down. As long as the coal is packed tight, air can’t freely reach the buried coal, and it doesn’t catch fire. So, dirt movers were constantly driving back and forth on the coal pile to keep the coal well packed. Even on the picture of the coalyard above from the smoke stack, you can see two pieces of heavy equipment out on the coal pile traveling back and forth packing the coal.
Anyway, the next phase in the life of the lump of coal happens when it finds itself directly under the stack out tower, and it is fed down by a vibratory feeder onto a conveyor. In our plant, these belts were called, Belts 4, 5, 6 and 7. Belts 4 and 5 fed onto Belt 8 and belts 6 and 7 fed onto belt 9.
Belts 8 and 9 brought the coal up from under the coal pile to the top of the Crusher tower. In the picture above you can see that tower to the right of the stack out tower with the long belts coming from the bottom of the tower toward the plant. The crusher tower takes the large lumps of coal that can be the size of a baseball or a softball and crushes it down to the size of marbles and large gumballs.
Coal conveyor carrying coal to the coal silos from the coalyard. This is the size of the coal after it has been crushed by the crusher
From the crusher tower the lump of coal which is now no more than a nugget of coal travels from the coal yard up to the plant on belts 10 and 11.
conveyor 10 and 11 are almost 1/2 mile long
Up at the top of this belt in the distance you can see another tower. This tower is called the Transfer tower. Why? Well, because it transfers the coal to another set of belts, Belt 12 and 13. You can see them going up to the right to that tower in the middle between the two boilers.
The tower between the two boilers is called the Surge Bin tower. That basically means that there is a big bin there that can hold a good amount of coal to feed to either unit. At the bottom of the white part of the tower you can see that there is a section on each side. This is where the tripper galleries are located. There are two belts in each tripper, and two belts that feed to each tripper belt from the surge bin. So, just to keep counting, Belts 14 and 15 feed to unit one and belts 16 and 17 feed to unit 2 from the surge bin. then Belts 18 and 19 are the two tripper belts that dump coal into the 6 silos on unit one, while belts 20 and 21 feed the silos on unit 2.
Once in the Coal silos, the coal is through traveling on belts. The silos are positioned over things called bowl mills. The coal is fed from the silo into the bowl mill through something called a Gravimetric feeder, which is able to feed a specific amount of coal into the bowl mill. This is the point that basically decides how hot the boiler is going to be.
Once the coal leaves the gravimetric feeder and drops down to the bowl mill, it is bound for the boiler. The gravimetric feeder is tied right to the control room. When they need to raise load more than just a minimal amount, a control room operator increases the amount of coal being fed from these feeders in order to increase the flow of coal into the boiler….. I don’t know… maybe it’s more automatic than that now…. The computer probably does it these days.
When the nugget of coal falls into the bowl mill the long journey from the coal mine in Wyoming is almost complete. Its short life as a nugget is over and it is pulverized into powder. The powder is finer than flour. Another name for a bowl mill is “Pulverizer”. The coal comes from the Powder River Basin in Wyoming and just before it is consumed in Oklahoma it really does become powder.
Big rollers are used to crush the coal into fine particles. The pulverized coal his blown up pipes by the primary air fans and blown directly into the boiler where they burst into flames. A bright orange flame. The color reminds me of orange sherbet Ice cream.
The color of the fireball in the boiler
At this point an incredible thing happens to the coal that so many years ago was a part of a tree or some other plant. The chemical process that trapped the carbon from the carbon dioxide millions of years earlier is reversed and the carbon is once again combined to the oxygen as it was many millennium ago. A burst of heat is released which had been trapped after a cooling effect below the tree as it sucked the carbon out of the environment way back then.
The heat is transferred to the boiler tubes that line the boiler. The tubes heat the water and turn it into steam. The steam shoots into the turbine that turns a generator that produces the electricity that enters every house in the country. The solar power from eons ago that allowed the tree to grow is being used today to power our world. What an amazing system.
To take this one step further, the carbon dioxide that is released into the atmosphere today is replenishing the lost carbon dioxide from many years ago. Back when plants could breathe freely. Back before the carbon dioxide level was depleted almost to the point of the extinction of plant life on this planet. Remember, what we look on as a pollutant and a poison, to a plant is a chance to grow. The Sahara desert used to be a thriving forest. Maybe it will be again some day.
So, there is the question of global warming. We humans are so short sighted sometimes. We want to keep everything the same way we found it when we were born. We try desperately to keep animals from becoming extinct. We don’t think about the bazillions (ok, so I exaggerate) of animals that were extinct long before man arrived. It is natural for extinction to occur. That is how things evolve. We are trying to keep a system the same when it has always been changing.
Years from now we may develop ways to harness the energy from the sun or even from the universe in ways that are unimaginable today. When that time arrives, let’s just hope that we remain good stewards of the world so that we are around to see it. I believe that the use of fossil fuels, (as odd as that may seem) is a major step in reviving our planet’s natural resources.

Glad Mark fought the good fight, still a sad story.

Great read. I love knowing how things work. As I read the sad story of the traveling electrician, I kept wondering if she could have pulled that off in today’s world of air travel.
when I went to the Christian College in Eugene Oregon, they forced me to take a course in biology at the University of Oregon. I willingly sat and listened to the mix of science and evolution. I admit their perspective was intriguing.
at the end of the class, the last day, the instructor asked each one of her students to tell how the class had affected their thinking.
each one gave the politically correct answer in a variety of form. all the while I sat joyfully waiting my turn.
my response hushed the class for a moment. (it’s been some decades ago so I have to paraphrase but let it be sufficient) “I’m impressed with all the material you’ve covered. it’s astounding to think of all the things that were. but for me this class has only glorified my God. because I realize that in his wisdom he created gasoline for my car.”
you’ve covered a lot of material in your post. and I’m impressed at your diligence to complete it. I thank God for His faithfulness that he has put into you. may He prosper your testimony for the glory of His Holy Son.

We processed several hobo’s through our coal system, & injured a few, but none ever got anything from the power company. I remember we would always worried about finding a chunk of scalp or something in the grating where the tripper car drops coal down into the silo. One especially memerable event was when a coal yard operator found a down vest jacket on the coal pile and bragged about how lucky he was to find this jacket, the size even fit, but the jacket did smell a little funny. yes it was ripped off the body of a hobo by the plow above conveyor one & shot out onto the coal pile by the stackout conveyor.
It was always unnerving to have a pullcord go down in the middle of the night deep down in the coal trestle, while the belts were shut down. You’d have to go down there alone, in the dark & reset the pull cords, so the belts could be started later when needed. You knew it wasn’t a trick because the whole crew had been up in the control room together eating dinner or something. You always wondered if you might run into a real hobo – or the ghost of one.
Power Plant Men 
The Janitors at Seminole showed me how the PPM (Power Plant Men) were spitting their tobacco juice inside I-beam webs, in tight corners, and other hard to clean spots. They asked me to put out a memo asking the spitters to just spit out in the middle of the floor so they could clean it up much easier, which I did. I can’t remember for sure, but it seems like the puddles of stinky gross slime around the Plant tailed off for a while.
Good story, Kevin. I hadn’t thought about Ray Eberle for a long time. He was a super turbine man I always enjoyed being around. I just remember his competence and his positive attitude.
