Power Plant Painting Lessons with Aubrey Cargill

I had the feeling it would be an interesting day when the first thing that Stanley Elmore asked me when I sat down for our morning meeting was, “Kelvin, are you afraid of heights?”  Well, since before that day I hadn’t been afraid of heights, I told him I wasn’t.  I decided not to mention that my name was really “Kevin”, since I thought he was only calling me “Kelvin” as a joke.

Then Stanley, who liked most of all to joke around with people, started hinting through facial expressions of excitement (such as grinning real big and raising his eyebrows up to where his hair line used to be when he was younger) and by uttering sounds like “boy, well, yeah…. huh, I guess we’ll see” while shaking his head as if in disbelief.  He told me to get with Aubrey after the meeting because there was a job I needed to help him out with. (Ok.  I know.  Ending a terribly constructed sentence with a preposition).

Aubrey Cargill was our painter.  He worked out of the garage that I worked out of the last 3 years of working as a summer help.  There was a paint room in the back of the garage on the side where the carpenter, Fred Hesser built cabinets and other great works of art.

Fred was the best carpenter I have ever met, as well as one of the finest gentlemen I have ever known.  He wasn’t in the category of Power Plant man, as he didn’t involve himself in most of the power plant operations or maintenance, but to this day, Power Plant Men from all over Oklahoma can visit Sooner Plant on overhaul and admire the woodworking masterpieces created by Carpenter Fred many years earlier.

I had worked with Aubrey my first year as a summer help.  The garage hadn’t been built yet, and Aubrey had not been assigned as a painter, as both units were still under construction.  Aubrey was the same age as my father and in his mid-forties that first summer.

His favorite buddy was Ben Hutchinson.  Whereever one went, the other was not far away.  All during the first summer, the lake on the hill was still being filled by pumping water up from the Arkansas river.

Most of the last two weeks that summer I worked with Aubrey and Ben picking up driftwood along the dikes that were built on the lake to route the water from the discharge from the plant to the far side of the lake from where the water enters the plant to cool the condensers.  The idea is that the water has to flow all the way around the lake before it is used to cool the condenser again.  So, Ben and Aubrey took turns driving a big dump truck down the dike while I walked down one side of the dike around the water level and Aubrey or Ben walked down the other side, and we would toss wood up the dike into the dump truck.

This was quite a throw, and often resulted in a big log being tossed up the dike just to hit the side of the dump truck creating a loud banging sound.  Anyway, when you consider that there are probably about 6 miles of dikes all together, it was quite a task to clean up all the driftwood that had accumulated in this man made lake.  After doing this for two weeks I learned the true meaning of the word “bursitis”.

After the morning meeting with Stanley Elmore I followed Aubrey into the carpenter shop, where he pointed to two buckets of paint that I was to carry, while he grabbed a canvas tool bag filled with large paint brushes and other painting tools and some white rope that looked like it had the seat of wooden swing on one end.  Aubrey nodded to Fred, and I understood by this that Fred had created the wooden swing that had four pieces of rope knotted through each of the corners of the seat and were connected to the main rope using some kind of small shackle.  When I asked Aubrey what that was, he told me that it is was a Boatswain Chair.  “Oh.” I think I said, “It looks like a swing.”

On the way to the boilers, we stopped by the tool room and I checked out a safety belt.  I could see Aubrey nodding at Bud Schoonover about my having to check out a safety belt, and what implication that had.  I of course preferred to think that my fellow employees would not purposely put me in harms way, so I went along acting as if I was oblivious to whatever fate awaited me.

We took the elevator on #1 Boiler to the 11th floor (which is actually about 22 stories up.  There are only 12 stops on the boiler elevator, but the building is really 25 stories to the very top.  So Power Plant men call the extra floors things like 8 1/2 when you get off the elevator where it says 8, and go up one flight of stairs.

Aubrey explained to me that we need to paint a drain pipe that is below us a couple of floors that goes down from there to just above floor 7 1/2 where it turns.  He said that he could paint the rest, but he needed my help to paint the pipe where it drops straight down, because there isn’t any way to reach it, except by dropping someone off the side of the boiler over a handrail and lowering them down to the pipe, and that turned out to be me.

He explained how the safety belt worked.  He said that I clip the lanyard in the ring at the top of the boatswain chair so that if I slip off the chair I wouldn’t fall all the way down, and then he could gradually lower me on down to the landing.

He didn’t explain to me at the time that the weight of my body free-falling three feet before coming to the end of the lanyard would have been a sufficient enough force to snap the white rope in half.  I guess he didn’t know about that.  But that was ok for me, because I didn’t know about it either — at the time.  We didn’t use Safety Harnesses at that time.  Just a belt around the waist.

So as I tied the canvas bag to the bottom of the chair, I saw Aubrey quickly wrap the rope around the handrail making some sort of half hitch knot.  I wasn’t too sure about that so I asked Aubrey where he learned to tie a knot like that and he told me in the Navy.  That was all I needed to hear.  As soon as he told me he learned knot tying in the Navy, I felt completely secure.  I figured if anyone knew the right way to tie a knot it’s someone in the Navy.

I clipped the lanyard in the shackle at the top of the boatswain chair and headed over the handrail.  I situated the chair to where I had my feet through it when I went over and the chair was up by my waist.  As I lowered myself down, I came to rest on the boatswain chair some 210 feet up from the ground.

It is always windy in this part of Oklahoma in the summer, and the wind was blowing that day, so, I began to spin around and float this way and that.  That continued until Aubrey had lowered me down to the pipe that I was going to paint and I was able to wrap my legs around it and wait for my head to stop spinning.

Then Aubrey lowered down another rope that had a bucket of paint tied to it.   Then I began my job of painting the pipe as Aubrey had hold of the rope and was slowly lowering me down.  Luckily Aubrey didn’t have to sneeze, or wasn’t chased by a wasp while he was doing this.  Thinking about that, I kept my legs wrapped around the pipe pretty tight just in case Aubrey had a heart attack or something.

The pipe really did need painting.  So, I knew this wasn’t completely just a joke to toss me out on a swing in the middle of the air hanging onto a rope with one hand while attempting to paint a pipe.  It had the red primer on it that most of the piping had before it was painted so it looked out of place with all the other silver pipes, but I couldn’t help thinking about Jerry Lewis in the Movie, “Who’s Minding the Store” where Jerry Lewis is told to paint the globe on the end of a flagpole that is located out the window on a top floor of the building, and he begins by trying to climb out on the flagpole with a bucket of paint in his mouth with little success.  But like Jerry, I figured it had to be done, so I just went ahead and did it.

Fortunately, I found out right away that I wasn’t afraid of heights, even at this height and under these conditions.  So, instead of fainting away, I just painted away and finally ended up on floor 7  1/2 which is right next to the Tripper Gallery.  I think I finished this a little after morning break but I don’t think Aubrey wanted to stop for break just to lower me down and then have to start from the top again lowering me all the way down one more time.

This brings me to another point.  Notice where I landed.  Right next to the Tripper Gallery.  Power Plant ingenuity has a way of naming parts of the plant with interesting names.  The first time I heard that we were going to the tripper gallery to shovel coal, I half expected to see paintings lining the walls.  It sounded like such a nice place to visit…. “Tripper Gallery”.  It sort of rolls off your tongue.  Especially if you try saying it with a French accent.

The Tripper Gallery is neither eloquent nor French.  It is where the coal from the coal yard is dumped into the Coal Silos just above the Bowl Mills.  — Yes.  Bowl Mills.  I know.  It sounds like a breakfast cereal.  Almost like Malt-O-Meal in a bowl.

So, the Tripper Gallery is a long narrow room (hence the word Gallery), and there are two machines called Trippers that travels from one silo to the next dumping coal from the conveyor belt down into the coal silo, and when the silo is full, a switch is triggered (or tripped) which tells the machine to go to the next silo.  Since the switch “trips” and tells the machine to move, they call the machine the “Tripper”.

I know.  That last paragraph didn’t have anything to do with painting the drain pipe.  But I thought since I mentioned the Tripper Gallery, I might as well explain what it is.  Anyway, when we returned to the shop I watched as Stanley Elmore went over to Aubrey to see how I did when I found out he was going to drop me over the side of the boiler in a wooden chair.  I could see that Aubrey gave him a good report because Stanley looked a little disappointed that this Power Plant Joke (even though essential), hadn’t resulted in visibly shaking me up.

Spending Long Weekends with Power Plant Men Shoveling Coal

Originally posted on:  June 1, 2012

The first couple of years while I worked as a summer help at the Coal-Fired Power Plant Coal Cleanup was performed on weekends by volunteer He-Men that wanted to make a few extra dollars.  As a summer help, I needed all the extra money I could get.  My wages during the first year (1979) were $3.89 an hour.

This jumped to $5.84 an hour when I worked on the weekend, so you can imagine the thrill I had at receiving a paycheck that included the extra money made by doing “Coal Cleanup”.  Another great advantage to doing coal cleanup on the weekends was that I was able to carpool with different people.  So, during the first summer instead of just riding to work with Steve Higginbotham (See the post “Steve Higginbotham’s Junky Jalopy late for the Boiler Blowdown“), I caught a lot of rides with real Power Plant Men like Dale Hull, David Hankins, Jerry Mitchell, Preston Jenkins and Marlin McDaniel (Yeah.  Marlin McDaniel as an A Foreman would volunteer for coal cleanup some times.  Maybe it was when we were short a few people).

Coal Cleanup really became important during the second half of the first summer because Unit 1 was getting ready to go online.  There was a major flaw in the Coal Conveyor logic when the conveyors first started conveying coal from the coal pile to the coal silos just above the bowl mills.  What would happen was the same thing that happens if someone were to fall down at the top of a crowded escalator going up.  Everyone behind that person would be shoved right on top of them if there wasn’t an emergency stop button to stop the escalator.

Escalator

All the conveyors had a safety cord alongside the entire length that could be pulled to stop the conveyor in an emergency, but this was something different.

To give you an idea… once the coal on the coal pile has been fed onto either Belts 4, 5, 6 or 7, from there the coal is dropped onto either belt 8 or 9.  That carries the coal up to the coal Crusher which has a bin above the crusher that can be filled with coal.  If the bin gets too full, then conveyor 8 and/or 9 would stop.  When that happens, belts 4, 5, 6 or 7 should stop also…. only they didn’t.  Belts 8 and 9 continued dumping coal into the crusher bin until it filled up and then coal fell out all over the top of the crusher tower around belts 8 and 9 until the coal tripped the belt by hitting the safety cord on the side of the belt.  Belts 4, 5, 6 and 7 continued dumping coal onto belts 8 and 9, which caused the coal to backup and spill out all over the floor until the coal piled up high enough to trip the safety cord on the side of the belt.

In the picture of the power plant on the side of this post, there is one long conveyor that goes from the coalyard to the plant.  It is about 1/2 mile long.  This is where belts 10 and 11 carry the coal from the crusher, which crushes the coal down from big pieces the size of baseballs down to the size of walnuts.

The long belts 10 and 11 were like these only they are in a metal enclosure so the coal didn’t spill out on the ground.

At the top of the Transfer tower the coal from belts 10 and 11 are dumped onto belts 12 and 13 which carry the coal up to the Surge Bin Tower where the coal is dumped into the Surge bin.  Now when the Surge Bin fills up, it stops belts 12 and/or 13 and it should also stop belts 10 and 11 and the feeders that feed the coal into the crusher at the bottom of the crusher bin… only they didn’t.

They continued dumping coal into the Surge bin, which filled up and spilled coal all over the surge bin until belts 12 and 13 tripped, at which point, coal began spilling out all over the transfer tower filling up both floors of the transfer tower with tons of coal.  The same thing would happen at the bottom of Belt 10 and 11, where the crusher feeders kept feeding coal down to belts 10 and 11, which spilled out all over the bottom floor of the crusher tower.

I have worked in the transfer tower where the coal was higher than the windows and you had to bend over because your head would hit the ceiling on the floor at the foot of belt 12 and 13.  It was almost dangerous enough to picture yourself sliding down the pile of coal and slipping right out one of the windows (which had been broken out by the pile of coal).  To give you an idea of what this felt like, it was then a straight drop of 150 feet to the concrete below.

If that doesn’t seem like enough coal spills, then picture this…  The coal from the Surge Bin tower fed onto belts 14, 15, 18 and 19 which in turn fed onto belts 16 and 17, 20 and 21.  These last 4 belts were in what was called the “Tripper Gallery”.  These 4 belts would dump coal into 12 coal silos (6 on each unit) that would feed the bowl mills. These are big silos about 5 stories tall.

The same thing would happen to these belts leaving piles of coal at the bottom of the surge bin in the surge bin tower and all along the tripper gallery because when the coal silos were full, the tripper was supposed to move to the next silo and dump coal until it was full, and keep moving until all the silos were full.  Only, the tripper wasn’t working correctly, so it wouldn’t detect that the silo was full so the belt would keep dumping coal and would end up spilling coal all over the entire tripper gallery which runs about 100 feet or so.

So, our first experience with doing coal cleanup was like being on a chain gang where we shoveled coal from morning until night trying to clean up these 15 or so major coal spills by shoveling the coal back onto the conveyor while it was running.  In some cases, we had to shovel the coal away from the belt before the belt could even run (as was the case with belts 12 and 13).  So, you can imagine how shoveling coal one scoop at a time made it seem like you were not getting anywhere fast.  3 or 4 men could all be shoveling on one pile of coal for 30 minutes and not even make a noticeable dent in the pile.  That is why when I went to the tool room to choose a shovel, instead of picking a regular shovel, I picked a large scoop shovel used to scoop grain.

Scoop Shovel

Regular Shovel

Even though each scoop of coal was heavier, it seemed more satisfying to see the bigger dent in the pile of coal with each shovelful.  I remember one day after we had shoveled coal all day from morning until late at night only to come back into work the next morning to the new piles of coal just as big as the ones we had shoveled the day before.

After 2 years of volunteer coal cleanup which was becoming less volunteer and more rotational since the list of volunteers was growing smaller, Ray Butler pointed out that it didn’t make much sense to pay a first class machinist overtime to shovel coal when you could create a labor crew and pay them bottom dollar to do coal cleanup all the time, as well as other dirty jobs that no one really wanted to do (such as suck out sewage pits and other sump pits around the plant).

That was when the Labor crew was formed.  While I was in my 3rd year as a summer help (1981).  Bill Cook was a summer help then that stayed on as a labor crew hand at the end of the summer.  By the 4th summer as summer help, the only time we did coal cleanup was when there was a major spill, which was only a couple of times all summer.

I will write later about coal cleanup with Dale Hull.  I also remember doing coal-cleanup with Preston Jenkins one weekend.  I hadn’t carpooled with him to work, but I caught a ride back to Stillwater with him because my ride left at the end of a full day, and I decided to stay behind to add a few extra dollars to my bank account.  We left a couple of hours later around seven o’clock.

I climbed into the back of Preston’s Camaro.  I apologized for being so dirty, as I was covered from head-to-toe in coal-dust and my clothes were soaked with coal-dust permeated sweat.  Preston said that he didn’t mind.  I soon found out why.

When I climbed into the backseat of his car, I noticed that the upholstery that covered the seat back of the back seat was stained with some blackish-brownish um…. something.  Anyway.  I decided to sit on the passenger side of the back seat instead of behind the driver side because that side wasn’t nearly as stained.  As we drove down the highway toward home, I quickly learned why the seat back was so stained.

Being the “good-ol’ boy” that Preston was, when he climbed into the car, he took out his can of Skoal and put a pinch between his cheek and gums:

Just a pinch between your cheek and gums.... Never tried it myself.

Just a pinch between your cheek and gums…. Never tried it myself.

As we flew down the highway like a Texan heading for Stillwater, Preston would lean his head out the window and squirt out a wad of spit.  It would dance in the air like a little fairy just before it would be sucked into the back window of his car and splat against the seat back of the back seat.  Yep that explained it all right.  I always wondered if he knew, never having to sit in the back seat of his own car.

During the first summer when I was able to catch a ride with David Hankins a couple of times.  He was the crane operator at the time and drove a black Trans Am.  He was a black man with a very broad chest that never seemed to tire while doing coal cleanup.  From the first day he always treated me with great respect which in turn gave me a great respect for him.  I had him classified as a true Power Plant Man.

The second summer when I had been back at the plant for a couple of weeks, one day when Jim Heflin and I were going somewhere in a yellow Cushman cart, I asked Jim why I hadn’t seen David Hankins around.

A Cushman Cart Like this only Yellow

Jim (who hadn’t been at the plant the first summer) stopped the cart in the middle of the road and looked at me very solemnly and told me that David Hankins had died in a car accident in the spring.  He had been going home from a Men’s Club event when he was killed.  Because of this, alcoholic beverages were no longer allowed at Men’s Club events.  As with all the people I have worked with at the power plant, I keep David Hankins in my memory and I often think about him to this day.  David Hankins was a True Power Plant Man.

    We’ve lost so many friends over the years, in the plants and on the line, especially when they were relaxing on their way home. You, and David’s family have my very belated condolences.

    Somebody, somewhere, needs to teach engineers a course on Conveyor Logic 101, I’ve seen the same thing happen in nearly every plant (from automotive, rarely, to meat packing, often) I’ve been in. Or they could, just for once in their life, shut their pie-hole and listen to people like you and me.

      Thanks Nebraska.

      We were often exhausted while driving home from work when we had been working a lot of overtime. It was a wonder sometimes that we were able to keep the car on the road.

      My uncle Bill Breazile worked for the Utility company in Nebraska City where someone closed a breaker while he was working on a line. He was in the hospital for about 6 months healing from his burns. This was about 30 years ago. He has since passed away. It takes a special person to be a lineman. Putting their life on the line every time they reach out to do their job.

        Not that different from you. It’s all about planning your work, and doing it right, and safely. You and I know that 480 will kill you just as quick as 7200 if you get careless. That’s why almost all (old) linemen and electricians are in some sense stolid and unexcitable.

    Industrial America returns in stories and comments in places like this, from the only place it still exists: the minds of those who were part of it. Industrial America was a giant; those who manned it were giant tamers and it seems to me, very much the special breed illuminated in these posts…

      I remember a time when I would have chose the bigger shovel, perhaps in the early 70’s. I was moving steel in a manufacturing plant. Carrying three bars on each shoulder seemed better than the two they suggested. We finished earlier, had to do other work, but somehow it felt better. Thanks for another interesting story and a wake-up call to younger days. Thanks also for the explanations. I love mechanical things and I get the impression that these plants are one big mechanical adventure.

Luxuries and Amenities of a Power Plant Labor Crew

When I was a janitor at the Power Plant there were times when we were christened by being allowed to work with the Labor Crew on jobs that needed to be done in a hurry.  Larry Riley was the foreman of the Labor Crew.  I had worked with Larry Riley during the summers when I was a summer help, and I always held him in high esteem.

I think he knew that, and he said he was glad to have me working for him whenever they were in a pinch to complete a job in a hurry.  I have described Larry as reminding me of the Marlboro Man, as he had a moustache that looked like his.

Yep. That’s the Marlboro Man

I finally found a picture of Larry taken a couple of decades later… Here he is:

The wonderful thing about working in a Power Plant is that when you drive through the gate in the morning, you never know what you might be doing that day.   Even after 20 years at the plant, I was still amazed by the diversity of jobs a person could do there.  Anyone who spent those 20 years actually working instead of doing a desk job, would know a lot about all kinds of equipment and instruments, and temperatures.

When I was young I was able to go to Minnesota to visit my cousins in a place called “Phelp’s Mill”.  Named after an old mill along a river that was a “self service” museum.  Across the road and on the hill loomed a big foreboding house where my cousins lived during the summers.  We would play hide-and-seek in that mill, which was mainly made out of wood.  It was 4 stories high if you include the basement and had a lot of places to hide.

This is a picture of the inside of Phelps Mill by Shawn Turner: http://www.flickr.com/photos/32364049@N04/7174048516/

When I began working in the Power Plant, I realized one day that this was like that old mill only on a much bigger scale.  You could spend half of a life time wandering around that plant before you actually knew where everything was.  Each day brought something new.  My first years as a summer help, most of the “emergencies” that I would take part in had to do with cleaning up coal.  When I was able to work with the Labor Crew, things became a lot more interesting.

One day in the spring of 1983 when I arrived at work ready to mop the floor and sweep and dust the Turbine Generators, I was told that I needed to get with Chuck Ross an A foreman over the Labor Crew at the time, because I was going to work with the Labor Crew that day.  I was told to bring my respirator… Which usually had meant it was time to shovel coal.  This day was different.

Chuck brought me to the Tool room and asked Bif Johnson to give me a new Rubber Mallet.

New Rubber Mallet just like this

I went with the labor crew up on #1 Boiler just above the Air Preheater Baskets that I didn’t know existed at the time…  The Boiler had been shutdown over night because there was a problem with the airflow through the boiler and we had to go in the duct and clean the Slag Screen.

Diagram of a boiler

Below the Economizer and above the air preheater in the diagram above.

“Slag Screen,” I thought… That sounds like a fancy word for something that was  probably just some kind of filter or something….  I knew that Power Plant Engineers liked to give fancy words to make the Plant sound more like a Palace.

As I mentioned before… there are places like:  The Tripper Gallery.  Hopper Nozzle Booster Pump. Generator Bathtub.  The Gravimetric Feeder Deck — I liked that one, it sounded like you were on a ship.  Travelling Water Screens.  There were long names for some, like “Force Draft Fan Inboard Bearing Emergency Lube Oil Pump” (try saying that with a lisp).  Anyway, I could go on and on.

Larry Riley explained to us that we needed to work as fast as we could to clean the slag screen because they wanted to bring this unit back online in the evening.  We couldn’t wait for the unit to cool down much, so we were only allowed to go in the hot air duct for 10 minutes at a time because of the heat.

So, in I went.  The first thing I noticed as I stuck my head in the door was that there wasn’t any immediate place to stand.  There was only a hole below me that went down into the darkness.  So I looked around for something to grab onto to pull myself in.  Once my body was in the door I was able to walk along a beam next to this big screen.  It looked similar to a screen on a window at home only the wires were about 1/2 inch apart.  Something like this:

A picture of a similar slag screen

Oh, and there was one more thing that I noticed…. It was incredibly HOT.  I was wearing leather gloves so I could grab onto the structure to hold myself up, but if I leaned against the screen with my arm, it would burn it.  I was just wearing a tee shirt.  I don’t know the exact temperature, but I have worked in similar heat at other times, and I would say that it was around 160 degrees.  I was not wearing my  hard hat because there was a strong wind blowing to try and cool the boiler down.

The problem is that we were on the tail end of the air flowing out of the boiler, and it was carrying all that heat right onto us.  At 160 degrees your hard hat will become soft so that you can squish it like a ball cap.  I was wearing Goggles as well, and that helped keep my eyes from drying out since everything else went dry the moment I stuck my head in there.

Anyway, I threw the lanyard for my safety belt around a pipe that ran diagonal across my path, and held onto it with one hand while with my other hand I began pounding on the screen with the rubber mallet.  I had to breathe very shallow because the air was so hot.  Breathing slowly gave the air time to cool off a bit before it went down into my throat.

This was a new adventure for me.  There are some Brave Power Plant Men that work on the “Bowl Mill” crew that have worked in these conditions for weeks at a time.  I suppose you grow used to it after a while.  Kind of like when you eat something with Habenero Sauce.  The first time it just very painful.  Then a few weeks later, you’re piling it on your tortilla chips.

After my first 10 minutes were over, someone at the door, (which was hard to see) hollered for me, so I made my way back to the door and emerged into the cool air of the morning.  I noticed that Larry Riley gave me a slightly worried look and I wondered what it meant.  I realized what it was moments later when I went to remove the respirator off of my face.  I only had one filter cartridge in the respirator.

Half-face respirator

The other one was missing.  I thought that was silly of me to go in there with only one filter.  No wonder it seemed like I was breathing a lot of dust.  Then I thought…. No.  I know I had both filters when I went in the duct.  I must have lost one while I was in there.  Maybe with all that banging I knocked it off.

Anyway, 10 minutes later it was time for me to go back in there, and this time I made sure my filters were securely screwed onto the respirator.  I worried in the back of my mind that I may have ruined my lungs for life by breathing all that silicon-based fly ash because I was feeling a little out of breathe (for the next 10 years).

Anyway, halfway through my 10 minutes in the duct I reached up with my hand to make sure my filters were still tightly screwed in place, and to my astonishment, they weren’t tight.  I tried tightening them, but I couldn’t screw them tight.  The respirator itself had become soft in the heat and the plastic was no longer stiff enough to keep the filter tight.  It made sense then why I had lost my filter the first time.  It must have fallen down into the abyss of darkness that was right behind me while I was banging on that slag screen.

After working on the screen for an hour or so, we took a break.  When we returned the temperature in the boiler had dropped considerably, and I was able to stay in the duct the rest of the day without having to climb in and out all the time.

Larry had an air powered needle gun brought up there and someone used that for a while cleaning the screen.  It is what it sounds like.  It has rods sticking out the end of a gun looking tool that vibrate wildly when you pull the trigger.  I don’t know what the real name is for it, but it cleaned slag screens a lot faster than my beating the screen with the rubber mallet all day.

Needle Gun

I did beat that screen all day.  When it was time to leave I brought the mallet back to the tool room, and it looked like this:

Rubber Mallet after banging on a slag screen all day

I had worn the rubber off of the  mallet.  When I brought the mallet back to the tool room, Bif said, “What is this?”  I said I was just returning the mallet that I had borrowed that morning.  He said something about how I must be some kind of a he-man or crazy.   I was too worried about my lungs to think about how much my wrists were aching from taking that pounding all day.

A couple of months later I was promoted to the Labor Crew.  Chuck Ross had kept saying that he couldn’t wait for me to go to the Labor Crew because he wanted me to work for him.  The very day that I started on the Labor Crew, the plant had a going-away party for Chuck Ross.  He was leaving our plant to go work at another one in Muskogee.

During the party Chuck presented me with the rubber mallet that I had used that day cleaning the slag screen.  He said he had never seen anything like that before.  He was sorry he was going to leave without having the opportunity to have me working for him.

I felt the same way about Chuck.  I have always kept that rubber mallet laying around the house since 1983 when I received it.  My wife sometimes picks it up when she is cleaning somewhere and says, “Do you still want this?” With a hopeful look, like someday I may say that it is all right if she throws it away.

Of course I want to keep it.  It reminds me of the days when I was able to work with True Power Plant Men in their natural environment.  The slag screen was later deemed unnecessary and was removed from the boiler.

It also reminds me of other things.  Like how quickly something can happen that changes your life forever.

Questions from that day have always remained with me.

How much ash did I breathe in?  I couldn’t see much more than a few feet in front of me as I banged on that screen knocking ash down all over me.  What did it do to my lungs?

What if I had taken a step back or slipped off of that beam before I had walked to the other end to secure my safety lanyard?  I know now what was below me then.  I would have fallen about 20 feet down to some fins, and then down another 20 feet onto the air preheater baskets.  It would have taken a while to retrieve me, once someone figured out that I was missing.

What does that much heat do to your body… or your brain?

I know these are things that go through the minds of True Power Plant Men.  I worked with them for years improving the safety of the power plant.  All-in-all, no one ever died when I was there, though some came close.  The Slogan over the Shift Supervisor’s Office said, “Safety is job #1”.  That wasn’t there to try to convince us that Safety was important.  It was there as a testimony to everyone who had already made that decision.

    GLAD that you made it….even if the mallet didn’t!!!

    I can dig it. When I was hired for Security at one post…I really looked forward to working with and for that particular Supervisor who’d hired me. No such luck–she was gone in a month or two. THAT hurt! 🙂

    If the environment is too hot for a respirator to function properly in, it’s too hot for people to work in (if safety is actually job #1). I saw too many examples of “Get the Unit Back On is Job #1″.

 

Not a Fan of French Power Plant Fan Filters

Originally posted August 2, 2013:

I had only been an electrician a couple of months before I heard about Power Plant Louvers. My first thought was that this was a mispronunciation of the word “Louvre”. I remembered how Marland McDaniel would pronounce the word “Italian”. He pronounced it “It-lee-un”. The first time he said that I asked him what he had said, and he said, “So, You’re an It Lee Un Huh? An It-Lee-Un from It-Lee. Meaning “An Italian from Italy”.

So, when I heard the word Louver, I immediately said to myself “ok. They are probably trying to say the word “Louvre” (pronounced “Loove” which rhymes with “move”). Why shouldn’t they be trying to say the name of the most famous museum in the world. After all. When Sonny Karcher wanted to say there were a lot of things, he would say that there were “boo-coos” of them, When I asked him what “Boo-coos” meant he explained that it was French for “A lot”. Then I understood that he was mispronouncing the word “Beau-coup” (pronounced: “Bo Coo”). I suspected that everyone knew about the Louvre in Paris, France. I had first visited the Louvre in 1974 when I was 13 with my father on our way from Rome to Liverpool which I mentioned in the post “Power Plant Snitch“.

The Louvre in Paris France.  The home of the Mona Lisa and the Venus De-Milo.

The Louvre in Paris France. The home of the Mona Lisa and the Venus De-Milo.

It didn’t surprise me that they may have named a motor after the Louvre (as we were told to go replace a Louver Motor when we were doing filters). I half expected it. I figured it was somewhere up in the Tripper Gallery which is where the coal feeds into the coal silos above the bowl mills. I explained about the Tripper Gallery in the post “Power Plant Painting Lessons with Aubrey Cargill“. I have expected to see painting lining the walls when I first entered the Tripper Gallery.

So. I mentioned that we were supposed to replace a Louver Motor while we were “Doing Filters”. As a new electrician (which in my head an electrician was a vision of “elitism” going about the plant fixing electric circuits and running conduit and pulling wire), I soon learned from my foreman Charles Foster that as an electrician we were responsible for anything that had a wire going to it. That meant… well. Just about anything, one way or another. From water fountains, to elevators, to air filters.

Air Filters? Really? Not that I minded changing out air filters. It was just the connection to being an electrician that was confusing me. Ok. I could understand the filters that were on motors. Since motors were something we worked on all the time. It was the air handling filters that I was having a trouble connecting. Needless to say. within a few months my expectations of what an “electrician” meant was much more down to earth.

Even though we were the “elite” group of magical maintenance men (and woman), we were also the team that was looked to for all sorts of other tasks that was too involved for the labor crew, and too vague to fit under Mechanical Maintenance, because somewhere, there was a wire attached. God forbid if a labor crew hand was electrocuted while changing out a bank of paper air filters. — Ok. It’s not like me to complain… — or maybe in my old age, it is becoming more common… I’m not sure.

So. In most houses there are two types of filters. There is what I would call a “Paper Filter”, and there is a “Metal Filter”. The paper filter is found in the air conditioner intake. You probably don’t change it out as often as you should, but you know what I’m talking about. The metal filter is probably over your stove in your oven vent. — Oh…. You didn’t think about that one? Better go clean it then….

The Power Plant is the same. There are both paper filters and metal filters, and things we would call “Bag Filters”. — Oh.. yes. and coffee filters… but I’m not going to talk about Coffee filters in this post other than to say that, “yes. We did have coffee filters also.”

Power Plant Coffee Maker Coffee Filter

Power Plant Coffee Maker Coffee Filter

Ok. A short side story… The person that was appointed to drive the truck was responsible for making sure the coffee maker was ready to go by break time. Only, when I was the designated truck driver I told everyone that I was not going to make the coffee. My reason was that I don’t drink coffee, and I wouldn’t know how to make a good cup of coffee and they could be sure that if I made it, it was going to be as thick as syrup. — The rest of the Electric shop agreed that it would not be a good idea for me to make their coffee, so either Andy or Dee made the coffee when I was on Truck Driver Duty. — End of side story.

So, when we were placed on Filter Duty… That meant that we went around the plant and changed out filters for air handlers, and we cleaned and coated the metal filters that were used on motors. This task took about a week. “A week?” you say? Yep. I don’t remember the exact numbers, though at one point in my career I had counted everyone of the them just to amuse my self… but just one air handler for the main switchgear had about 50 large paper filters and if I remember correctly had another 50 bag filters behind them.

Industrial Paper Air Handling Unit Filter

Here is the bag filters that usually were attached to the back side of the paper filters:

Industrial Air Handler Bag Filter

Industrial Air Handler Bag Filter. Except ours weren’t pink and they weren’t on a beach.

First we had to remove the old filters that were often crawling with various kinds of flying insects that had been stuck to the filters since they flew too close and were sucked onto the filter. Then we installed the new filters in their place on a wall made of a large metal frame designed specifically for these filters. I think the reason they have a picture of the beach with this bag filter is because usually when you are trying to fit the bag filter into the basket you often thought that you would rather be at the beach than doing this task.

So. In the coal-fired power plant in North Central Oklahoma, there were a set of very large motors that spun the large fans that blew air into the boiler and that blew the exhaust up the smoke stack. Each of these motors (and we have two of each kind), had a set of large metal filters on them. You had to remove a large panel bolted to the side of the motors to remove the filters. — The motors were almost always running when this was being done. After all. We can’t stop lighting Oklahoma City just because it’s time to clean the motor filters on the fans on the boilers….

The metal filters reminded me of the filters over the stove when i was a cook at Sirloin Stockade. We would have to take them out each night and run them through the dishwasher after all the dishes had been washed after closing. Then the dishwasher was put in a self-cleaning mode to clean out all the gunk from the filters.

Galvanized, Stainless Steel Framed Air Filter used in large motors.  This is a about 2 feet by 2 feet square.

Galvanized, Stainless Steel Framed Air Filter used in large motors. ours is a about 2-1/2 feet by 2 feet in the largest motors.

Then we had pump motors around the plant and down at the river that had smaller versions of these metal filters. Each of these metal filters were taken to the shop where we used a high pressure washer (one that would take the paint off of your car), and we would disintegrate the bugs that were stuck to these filters using the high pressure washer until the filters were cleaned. Then after letting them dry, we would coat them with a “filter coat” that would collect dust so that we wouldn’t have to wait too long before they were dirty again.

Well. There were some that didn’t like using the filter coat. Especially if they thought they might have to be cleaning the same filters themselves the next time. This happened when we decided to split the Filter Duty up between teams once. We decided that one team was going to be responsible for Unit 1 and the other team was going to be responsible for Unit 2, and we split up the air filters so that they were pretty evenly divided.

When we did this, an incredible thing happened. Each time we had to clean our filters, they were really dirty. Half the time the other team cleaned their filters they were not very dirty. It was obvious what was happening…. someone wasn’t using the filter coat. We all knew that it was “Ain’t My Mota” (translated “not my motor) Michael Rose. There was nothing anyone could really do about it. His foreman tried and tried to reform him, but there was really only one cure.

Talking about “Ain’t My Mota” Michael reminds me of one guy that was on our crew, Gary Wehunt. It wasn’t that he cut corners. It’s just that he always wanted to do the easiest jobs first and work his way up to the worse jobs. I was the other way around. I always wanted to get the tough jobs over with right away, and then cruise on down to the easier jobs.

So, when I was working with Dee (Diana Brien) cleaning motor filters, we would start with the bowl mill motors and then work our way over to the big fan motors. Then we would end up down at the river cleaning the river pump motor filters. When I was working with Gary, he always wanted to go straight to the river pumps. I always had the feeling that he thought that there might be a chance that by the time the Bowl Mill motors (which were always caked with Coal Dust) he would be called off to go work on an air conditioner instead. To each their own.

So. What is a Louver? I guess I forgot to mention that. A Louver is the metal flap that opens to let the air in. When the air handler is off, the louver closes. Before it starts up, the Louver opens so the air can pass through the filters. It is like a set of blinds on a window. The Louver Motor opens and closes the Louvers:

Large Metal Louvers for an Industrial Air Handler

Large Metal Louvers for an Industrial Air Handler

Today I am not able to change out the filter for my air conditioner in my house without having a flashback to the time I spent replacing filters at the plant covered with dirt, coal dust, fly ash and bugs. I had reminded myself often early on after I joined the electric shop as an electrician what Charles Foster had told me when i was still a janitor.

In my new job I sit in a clean office area with people sitting all around typing away on their computers or talking to one another. But out of the corner of my ear I can hear the noise every so often up in the ceiling above the false ceiling of the air handler louvers adjusting the air flow as the climate control detects that more air is needed in another area.

My coworkers may think I’m sort of strange (for a lot of reasons, but one of them may be) because as I’m working away on the computer apparently oblivious to what is going on around me, I may suddenly break out in a big smile. Why? They may wonder. Because I can hear that louver slowly changing position. They sound like they are pneumatically controlled, but there is no mistaking the distinct low grind of the flaps as they slowly change. So, without stopping what I’m doing, a grin may appear on my face.

Charles had come up to me when I was a janitor while I was working on the floor scrubber in the main switchgear and asked me if I would think about becoming an electrician. He said that a lot of being an electrician was cleaning things. He had noticed that I took a lot of pride in the way I cleaned and that he thought I would make a good electrician.

I did enjoy being a Janitor and having someone encourage me to become an electrician was all I needed to pursue the honorable trade of “Electrician”. It didn’t take me long once I joined the shop to learn that Charles wasn’t stretching the truth when he said that a lot of what an electrician does is clean things.

I spent 18 years as an electrician at the Power Plant before moving on. Throughout that time, my wife never knew what to expect when I came home from work. My clothes could be just as clean as when I left in the morning, or (most likely), they would be covered with Soot or Coal Dust from the Coal-Fired Power Plant in North Central Oklahoma. One thing she could usually count on when I walked in the door was that I would have a smile on my face for having the privilege to spend a day at work with such a great group of Power Plant Heroes.

Lifecycle of a Power Plant Lump of Coal

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

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

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

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

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

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

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.

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.

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

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.

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

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.

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.

Luxuries and Amenities of a Power Plant Labor Crew

Originally Posted on August 11, 2012.  Added a picture of Larry Riley:

When I was a janitor at the Power Plant there were times when we were christened by being allowed to work with the Labor Crew on jobs that needed to be done in a hurry.  Larry Riley was the foreman of the Labor Crew.  I had worked with Larry Riley during the summers when I was a summer help, and I always held him in high esteem.

I think he knew that, and he said he was glad to have me working for him whenever they were in a pinch to complete a job in a hurry.  I have described Larry as reminding me of the Marlboro Man, as he had a moustache that looked like his.

Yep. That’s the Marlboro Man

I finally found a picture of Larry taken a couple of decades later… Here he is:

The wonderful thing about working in a Power Plant is that when you drive through the gate in the morning, you never know what you might be doing that day.   Even after 20 years at the plant, I was still amazed by the diversity of jobs a person could do there.  Anyone who spent those 20 years actually working instead of doing a desk job, would know a lot about all kinds of equipment and instruments, and temperatures.

When I was young I was able to go to Minnesota to visit my cousins in a place called “Phelp’s Mill”.  Named after an old mill along a river that was a “self service” museum.  Across the road and on the hill loomed a big foreboding house where my cousins lived during the summers.  We would play hide-and-seek in that mill, which was mainly made out of wood.  It was 4 stories high if you include the basement and had a lot of places to hide.

This is a picture of the inside of Phelps Mill by Shawn Turner: http://www.flickr.com/photos/32364049@N04/7174048516/

When I began working in the Power Plant, I realized one day that this was like that old mill only on a much bigger scale.  You could spend half of a life time wandering around that plant before you actually knew where everything was.  Each day brought something new.  My first years as a summer help, most of the “emergencies” that I would take part in had to do with cleaning up coal.  When I was able to work with the Labor Crew, things became a lot more interesting.

One day in the spring of 1983 when I arrived at work ready to mop the floor and sweep and dust the Turbine Generators, I was told that I needed to get with Chuck Ross an A foreman over the Labor Crew at the time, because I was going to work with the Labor Crew that day.  I was told to bring my respirator… Which usually had meant it was time to shovel coal.  This day was different.

Chuck brought me to the Tool room and asked Bif Johnson to give me a new Rubber Mallet.

New Rubber Mallet just like this

I went with the labor crew up on #1 Boiler just above the Air Preheater Baskets that I didn’t know existed at the time…  The Boiler had been shutdown over night because there was a problem with the airflow through the boiler and we had to go in the duct and clean the Slag Screen.

Diagram of a boiler

Diagram of a boiler

Below the Economizer and above the air preheater in the diagram above.

“Slag Screen,” I thought… That sounds like a fancy word for something that was  probably just some kind of filter or something….  I knew that Power Plant Engineers liked to give fancy words to make the Plant sound more like a Palace.

As I mentioned before… there are places like:  The Tripper Gallery.  Hopper Nozzle Booster Pump. Generator Bathtub.  The Gravimetric Feeder Deck — I liked that one, it sounded like you were on a ship.  Travelling Water Screens.  There were long names for some, like “Force Draft Fan Inboard Bearing Lube Oil Pump” (try saying that with a lisp).  Anyway, I could go on and on.

Larry Riley explained to us that we needed to work as fast as we could to clean the slag screen because they wanted to bring this unit back online in the evening.  We couldn’t wait for the unit to cool down much, so we were only allowed to go in the hot air duct for 10 minutes at a time because of the heat.

So, in I went.  The first thing I noticed as I stuck my head in the door was that there wasn’t any immediate place to stand.  There was only a hole below me that went down into the darkness.  So I looked around for something to grab onto to pull myself in.  Once my body was in the door I was able to walk along a beam next to this big screen.  It looked similar to a screen on a window at home only the wires were about 1/2 inch apart.  Something like this:

A picture of a similar slag screen

Oh, and there was one more thing that I noticed…. It was incredibly HOT.  I was wearing leather gloves so I could grab onto the structure to hold myself up, but if I leaned against the screen with my arm, it would burn it.  I was just wearing a tee shirt.  I don’t know the exact temperature, but I have worked in similar heat at other times, and I would say that it was around 150 degrees.  I was not wearing my  hard hat because there was a strong wind blowing to try and cool the boiler down.

The problem is that we were on the tail end of the air flowing out of the boiler, and it was carrying all that heat right onto us.  At 160 degrees your hard hat will become soft so that you can squish it like a ball cap.  I was wearing Goggles as well, and that helped keep my eyes from drying out since everything else went dry the moment I stuck my head in there.

Anyway, I threw the lanyard for my safety belt around a pipe that ran diagonal across my path, and held onto it with one hand while with my other hand I began pounding on the screen with the rubber mallet.  I had to breathe very shallow because the air was so hot.  Breathing slowly gave the air time to cool off a bit before it went down into my throat.

This was a new adventure for me.  There are some Brave Power Plant Men that work on the “Bowl Mill” crew that have worked in these conditions for weeks at a time.  I suppose you grow used to it after a while.  Kind of like when you eat something with Habenero Sauce.  The first time it just very painful.  Then a few weeks later, you’re piling it on your tortilla chips.

After my first 10 minutes were over, someone at the door, (which was hard to see) hollered for me, so I made my way back to the door and emerged into the cool air of the morning.  I noticed that Larry Riley gave me a slightly worried look and I wondered what it meant.  I realized what it was moments later when I went to remove the respirator off of my face.  I only had one filter cartridge in the respirator.

Half-face respirator

The other one was missing.  I thought that was silly of me to go in there with only one filter.  No wonder it seemed like I was breathing a lot of dust.  Then I thought…. No.  I know I had both filters when I went in the duct.  I must have lost one while I was in there.  Maybe with all that banging I knocked it off.

Anyway, 10 minutes later it was time for me to go back in there, and this time I made sure my filters were securely screwed onto the respirator.  I worried in the back of my mind that I may have ruined my lungs for life by breathing all that silicon-based fly ash because I was feeling a little out of breathe (for the next 10 years).

Anyway, halfway through my 10 minutes in the duct I reached up with my hand to make sure my filters were still tightly screwed in place, and to my astonishment, they weren’t tight.  I tried tightening them, but I couldn’t screw them tight.  The respirator itself had become soft in the heat and the plastic was no longer stiff enough to keep the filter tight.  It made sense then why I had lost my filter the first time.  It must have fallen down into the abyss of darkness that was right behind me while I was banging on that slag screen.

After working on the screen for an hour or so, we took a break.  When we returned the temperature in the boiler had dropped considerably, and I was able to stay in the duct the rest of the day without having to climb in and out all the time.

Larry had an air powered needle gun brought up there and someone used that for a while cleaning the screen.  It is what it sounds like.  It has rods sticking out the end of a gun looking tool that vibrate wildly when you pull the trigger.  I don’t know what the real name is for it, but it cleaned slag screens a lot faster than my beating the screen with the rubber mallet all day.

Needle Gun

I did beat that screen all day.  When it was time to leave I brought the mallet back to the tool room, and it looked like this:

Rubber Mallet after banging on a slag screen all day

I had worn the rubber off of the  mallet.  When I brought the mallet back to the tool room, Bif said, “What is this?”  I said I was just returning the mallet that I had borrowed that morning.  He said something about how I must be some kind of a he-man or crazy.   I was too worried about my lungs to think about how much my wrists were aching from taking that pounding all day.

A couple of months later I was promoted to the Labor Crew.  Chuck Ross had kept saying that he couldn’t wait for me to go to the Labor Crew because he wanted me to work for him.  The very day that I started on the Labor Crew, the plant had a going-away party for Chuck Ross.  He was leaving our plant to go work at another one in Muskogee.

During the party Chuck presented me with the rubber mallet that I had used that day cleaning the slag screen.  He said he had never seen anything like that before.  He was sorry he was going to leave without having the opportunity to have me working for him.

I felt the same way about Chuck.  I have always kept that rubber mallet laying around the house since 1983 when I received it.  My wife sometimes picks it up when she is cleaning somewhere and says, “Do you still want this?” With a hopeful look, like someday I may say that it is all right if she throws it away.

Of course I want to keep it.  It reminds me of the days when I was able to work with True Power Plant Men in their natural environment.  The slag screen was later deemed unnecessary and was removed from the boiler.

It also reminds me of other things.  Like how quickly something can happen that changes your life forever.

Questions from that day have always remained with me.

How much ash did I breathe in?  I couldn’t see much more than a few feet in front of me as I banged on that screen knocking ash down all over me.  What did it do to my lungs?

What if I had taken a step back or slipped off of that beam before I had walked to the other end to secure my safety lanyard?  I know now what was below me then.  I would have fallen about 20 feet down to some fins, and then down another 20 feet onto the air preheater baskets.  It would have taken a while to retrieve me, once someone figured out that I was missing.

What does that much heat do to your body… or your brain?

I know these are things that go through the minds of True Power Plant Men.  I worked with them for years improving the safety of the power plant.  All-in-all, no one ever died when I was there, though some came close.  The Slogan over the Shift Supervisor’s Office said, “Safety is job #1”.  That wasn’t there to try to convince us that Safety was important.  It was there as a testimony to everyone who had already made that decision.

    GLAD that you made it….even if the mallet didn’t!!!

    I can dig it. When I was hired for Security at one post…I really looked forward to working with and for that particular Supervisor who’d hired me. No such luck–she was gone in a month or two. THAT hurt! 🙂

  2. Ron Kilman August 13, 2014

    If the environment is too hot for a respirator to function properly in, it’s too hot for people to work in (if safety is actually job #1). I saw too many examples of “Get the Unit Back On is Job #1″.

 

Not a Fan of French Power Plant Fan Filters

Originally posted August 2, 2013:

I had only been an electrician a couple of months before I heard about Power Plant Louvers. My first thought was that this was a mispronunciation of the word “Louvre”. I remembered how Marland McDaniel would pronounce the word “Italian”. He pronounced it “It-lee-un”. The first time he said that I asked him what he had said, and he said, “So, You’re an It Lee Un Huh? An It-Lee-Un from It-Lee. Meaning “An Italian from Italy”.

So, when I heard the word Louver, I immediately said to myself “ok. They are probably trying to say the word “Louvre” (pronounced “Loove” which rhymes with “move”). Why shouldn’t they be trying to say the name of the most famous museum in the world. After all. When Sonny Karcher wanted to say there were a lot of things, he would say that there were “boo-coos” of them, When I asked him what “Boo-coos” meant he explained that it was French for “A lot”. Then I understood that he was mispronouncing the word “Beau-coup” (pronounced: “Bo Coo”). I suspected that everyone knew about the Louvre in Paris, France. I had first visited the Louvre in 1974 when I was 13 with my father on our way from Rome to Liverpool which I mentioned in the post “Power Plant Snitch“.

The Louvre in Paris France.  The home of the Mona Lisa and the Venus De-Milo.

The Louvre in Paris France. The home of the Mona Lisa and the Venus De-Milo.

It didn’t surprise me that they may have named a motor after the Louvre (as we were told to go replace a Louver Motor when we were doing filters). I half expected it. I figured it was somewhere up in the Tripper Gallery which is where the coal feeds into the coal silos above the bowl mills. I explained about the Tripper Gallery in the post “Power Plant Painting Lessons with Aubrey Cargill“. I have expected to see painting lining the walls when I first entered the Tripper Gallery.

So. I mentioned that we were supposed to replace a Louver Motor while we were “Doing Filters”. As a new electrician (which in my head an electrician was a vision of “elitism” going about the plant fixing electric circuits and running conduit and pulling wire), I soon learned from my foreman Charles Foster that as an electrician we were responsible for anything that had a wire going to it. That meant… well. Just about anything, one way or another. From water fountains, to elevators, to air filters.

Air Filters? Really? Not that I minded changing out air filters. It was just the connection to being an electrician that was confusing me. Ok. I could understand the filters that were on motors. Since motors were something we worked on all the time. It was the air handling filters that I was having a trouble connecting. Needless to say. within a few months my expectations of what an “electrician” meant was much more down to earth.

Even though we were the “elite” group of magical maintenance men (and woman), we were also the team that was looked to for all sorts of other tasks that was too involved for the labor crew, and too vague to fit under Mechanical Maintenance, because somewhere, there was a wire attached. God forbid if a labor crew hand was electrocuted while changing out a bank of paper air filters. — Ok. It’s not like me to complain… — or maybe in my old age, it is becoming more common… I’m not sure.

So. In most houses there are two types of filters. There is what I would call a “Paper Filter”, and there is a “Metal Filter”. The paper filter is found in the air conditioner intake. You probably don’t change it out as often as you should, but you know what I’m talking about. The metal filter is probably over your stove in your oven vent. — Oh…. You didn’t think about that one? Better go clean it then….

The Power Plant is the same. There are both paper filters and metal filters, and things we would call “Bag Filters”. — Oh.. yes. and coffee filters… but I’m not going to talk about Coffee filters in this post other than to say that, “yes. We did have coffee filters also.”

Power Plant Coffee Maker Coffee Filter

Power Plant Coffee Maker Coffee Filter

Ok. A short side story… The person that was appointed to drive the truck was responsible for making sure the coffee maker was ready to go by break time. Only, when I was the designated truck driver I told everyone that I was not going to make the coffee. My reason was that I don’t drink coffee, and I wouldn’t know how to make a good cup of coffee and they could be sure that if I made it, it was going to be as thick as syrup. — The rest of the Electric shop agreed that it would not be a good idea for me to make their coffee, so either Andy or Dee made the coffee when I was on Truck Driver Duty. — End of side story.

So, when we were placed on Filter Duty… That meant that we went around the plant and changed out filters for air handlers, and we cleaned and coated the metal filters that were used on motors. This task took about a week. “A week?” you say? Yep. I don’t remember the exact numbers, though at one point in my career I had counted everyone of the them just to amuse my self… but just one air handler for the main switchgear had about 50 large paper filters and if I remember correctly had another 50 bag filters behind them.

Industrial Paper Air Handling Unit Filter

Industrial Paper Air Handling Unit Filter. They kind of look like Modern Art I suppose

Here is the bag filters that usually were attached to the back side of the paper filters:

Industrial Air Handler Bag Filter

Industrial Air Handler Bag Filter. Except ours weren’t pink and they weren’t on a beach.

First we had to remove the old filters that were often crawling with various kinds of flying insects that had been stuck to the filters since they flew too close and were sucked onto the filter. Then we installed the new filters in their place on a wall made of a large metal frame designed specifically for these filters. I think the reason they have a picture of the beach with this bag filter is because usually when you are trying to fit the bag filter into the basket you often thought that you would rather be at the beach than doing this task.

So. In the coal-fired power plant in North Central Oklahoma, there were a set of very large motors that spun the large fans that blew air into the boiler and that blew the exhaust up the smoke stack. Each of these motors (and we have two of each kind), had a set of large metal filters on them. You had to remove a large panel bolted to the side of the motors to remove the filters. — The motors were almost always running when this was being done. After all. We can’t stop lighting Oklahoma City just because it’s time to clean the motor filters on the fans on the boilers….

The metal filters reminded me of the filters over the stove when i was a cook at Sirloin Stockade. We would have to take them out each night and run them through the dishwasher after all the dishes had been washed after closing. Then the dishwasher was put in a self-cleaning mode to clean out all the gunk from the filters.

Galvanized, Stainless Steel Framed Air Filter used in large motors. ours is a about 2-1/2 feet by 2 feet in the largest motors.

Then we had pump motors around the plant and down at the river that had smaller versions of these metal filters. Each of these metal filters were taken to the shop where we used a high pressure washer (one that would take the paint off of your car), and we would disintegrate the bugs that were stuck to these filters using the high pressure washer until the filters were cleaned. Then after letting them dry, we would coat them with a “filter coat” that would collect dust so that we wouldn’t have to wait too long before they were dirty again.

Well. There were some that didn’t like using the filter coat. Especially if they thought they might have to be cleaning the same filters themselves the next time. This happened when we decided to split the Filter Duty up between teams once. We decided that one team was going to be responsible for Unit 1 and the other team was going to be responsible for Unit 2, and we split up the air filters so that they were pretty evenly divided.

When we did this, an incredible thing happened. Each time we had to clean our filters, they were really dirty. Half the time the other team cleaned their filters they were not very dirty. It was obvious what was happening…. someone wasn’t using the filter coat. We all knew that it was “Ain’t My Mota” (translated “not my motor) Michael Rose. There was nothing anyone could really do about it. His foreman tried and tried to reform him, but there was really only one cure.

Talking about “Ain’t My Mota” Michael reminds me of one guy that was on our crew, Gary Wehunt. It wasn’t that he cut corners. It’s just that he always wanted to do the easiest jobs first and work his way up to the worse jobs. I was the other way around. I always wanted to get the tough jobs over with right away, and then cruise on down to the easier jobs.

So, when I was working with Dee (Diana Brien) cleaning motor filters, we would start with the bowl mill motors and then work our way over to the big fan motors. Then we would end up down at the river cleaning the river pump motor filters. When I was working with Gary, he always wanted to go straight to the river pumps. I always had the feeling that he thought that there might be a chance that by the time the Bowl Mill motors (which were always caked with Coal Dust) he would be called off to go work on an air conditioner instead. To each their own.

So. What is a Louver? I guess I forgot to mention that. A Louver is the metal flap that opens to let the air in. When the air handler is off, the louver closes. Before it starts up, the Louver opens so the air can pass through the filters. It is like a set of blinds on a window. The Louver Motor opens and closes the Louvers:

Large Metal Louvers for an Industrial Air Handler

Today I am not able to change out the filter for my air conditioner in my house without having a flashback to the time I spent replacing filters at the plant covered with dirt, coal dust, fly ash and bugs. I had reminded myself often early on after I joined the electric shop as an electrician what Charles Foster had told me when i was still a janitor.

In my new job I sit in a clean office area with people sitting all around typing away on their computers or talking to one another. But out of the corner of my ear I can hear the noise every so often up in the ceiling above the false ceiling of the air handler louvers adjusting the air flow as the climate control detects that more air is needed in another area.

My coworkers may think I’m sort of strange (for a lot of reasons, but one of them may be) because as I’m working away on the computer apparently oblivious to what is going on around me, I may suddenly break out in a big smile. Why? They may wonder. Because I can hear that louver slowly changing position. They sound like they are pneumatically controlled, but there is no mistaking the distinct low grind of the flaps as they slowly change. So, without stopping what I’m doing, a grin may appear on my face.

Charles had come up to me when I was a janitor while I was working on the floor scrubber in the main switchgear and asked me if I would think about becoming an electrician. He said that a lot of being an electrician was cleaning things. He had noticed that I took a lot of pride in the way I cleaned and that he thought I would make a good electrician.

I did enjoy being a Janitor and having someone encourage me to become an electrician was all I needed to pursue the honorable trade of “Electrician”. It didn’t take me long once I joined the shop to learn that Charles wasn’t stretching the truth when he said that a lot of what an electrician does is clean things.

I spent 18 years as an electrician at the Power Plant before moving on. Throughout that time, my wife never knew what to expect when I came home from work. My clothes could be just as clean as when I left in the morning, or (most likely), they would be covered with Soot or Coal Dust from the Coal-Fired Power Plant in North Central Oklahoma. One thing she could usually count on when I walked in the door was that I would have a smile on my face for having the privilege to spend a day at work with such a great group of Power Plant Heroes.

Spending Long Weekends with Power Plant Men Shoveling Coal

Originally posted on:  June 1, 2012

The first couple of years while I worked as a summer help at the Coal-Fired Power Plant Coal Cleanup was performed on weekends by volunteer He-Men that wanted to make a few extra dollars.  As a summer help, I needed all the extra money I could get.  My wages during the first year (1979) were $3.89 an hour.  This jumped to $5.84 an hour when I worked on the weekend, so you can imagine the thrill I had at receiving a paycheck that included the extra money made by doing “Coal Cleanup”.  Another great advantage to doing coal cleanup on the weekends was that I was able to carpool with different people.  So, during the first summer instead of just riding to work with Steve Higginbotham (See the post “Steve Higginbotham’s Junky Jalopy late for the Boiler Blowdown“), I caught a lot of rides with real Power Plant Men like Dale Hull, David Hankins, Jerry Mitchell, Preston Jenkins and Marlin McDaniel (Yeah.  Marlin McDaniel as an A Foreman would volunteer for coal cleanup some times.  Maybe it was when we were short a few people).

Coal Cleanup really became important during the second half of the first summer because Unit 1 was getting ready to go online.  There was a major flaw in the Coal Conveyor logic when the conveyors first started conveying coal from the coal pile to the coal silos just above the bowl mills.  What would happen was the same thing that happens if someone were to fall down at the top of a crowded escalator going up.  Everyone behind that person would be shoved right on top of them if there wasn’t an emergency stop button to stop the escalator.

Escalator

All the conveyors had a safety cord alongside the entire length that could be pulled to stop the conveyor in an emergency, but this was something different.

To give you an idea… once the coal on the coal pile has been fed onto either Belts 4, 5, 6 or 7, from there the coal is dropped onto either belt 8 or 9.  That carries the coal up to the coal Crusher which has a bin above the crusher that can be filled with coal.  If the bin gets too full, then conveyor 8 and/or 9 would stop.  When that happens, belts 4, 5, 6 or 7 should stop also…. only they didn’t.  Belts 8 and 9 continued dumping coal into the crusher bin until it filled up and then coal fell out all over the top of the crusher tower around belts 8 and 9 until the coal tripped the belt by hitting the safety cord on the side of the belt.  Belts 4, 5, 6 and 7 continued dumping coal onto belts 8 and 9, which caused the coal to backup and spill out all over the floor until the coal piled up high enough to trip the safety cord on the side of the belt.

In the picture of the power plant on the side of this post, there is one long conveyor that goes from the coalyard to the plant.  It is about 1/2 mile long.  This is where belts 10 and 11 carry the coal from the crusher, which crushes the coal down from big pieces the size of baseballs down to the size of walnuts.

The long belts 10 and 11 were like these only they are in a metal enclosure so the coal didn’t spill out on the ground.

At the top of the Transfer tower the coal from belts 10 and 11 are dumped onto belts 12 and 13 which carry the coal up to the Surge Bin Tower where the coal is dumped into the Surge bin.  Now when the Surge Bin fills up, it stops belts 12 and/or 13 and it should also stop belts 10 and 11 and the feeders that feed the coal into the crusher at the bottom of the crusher bin… only they didn’t.

They continued dumping coal into the Surge bin, which filled up and spilled coal all over the surge bin until belts 12 and 13 tripped, at which point, coal began spilling out all over the transfer tower filling up both floors of the transfer tower with tons of coal.  The same thing would happen at the bottom of Belt 10 and 11, where the crusher feeders kept feeding coal down to belts 10 and 11, which spilled out all over the bottom floor of the crusher tower.

I have worked in the transfer tower where the coal was higher than the windows and you had to bend over because your head would hit the ceiling on the floor at the foot of belt 12 and 13.  It was almost dangerous enough to picture yourself sliding down the pile of coal and slipping right out one of the windows (which had been broken out by the pile of coal).  To give you an idea of what this felt like, it was then a straight drop of 150 feet to the concrete below.

If that doesn’t seem like enough coal spills, then picture this…  The coal from the Surge Bin tower fed onto belts 14, 15, 18 and 19 which in turn fed onto belts 16 and 17, 20 and 21.  These last 4 belts were in what was called the “Tripper Gallery”.  These 4 belts would dump coal into 12 coal silos (6 on each unit) that would feed the bowl mills. These are big silos about 5 stories tall.

The same thing would happen to these belts leaving piles of coal at the bottom of the surge bin in the surge bin tower and all along the tripper gallery because when the coal silos were full, the tripper was supposed to move to the next silo and dump coal until it was full, and keep moving until all the silos were full.  Only, the tripper wasn’t working correctly, so it wouldn’t detect that the silo was full so the belt would keep dumping coal and would end up spilling coal all over the entire tripper gallery which runs about 100 feet or so.

So, our first experience with doing coal cleanup was like being on a chain gang where we shoveled coal from morning until night trying to clean up these 15 or so major coal spills by shoveling the coal back onto the conveyor while it was running.  In some cases, we had to shovel the coal away from the belt before the belt could even run (as was the case with belts 12 and 13).  So, you can imagine how shoveling coal one scoop at a time made it seem like you were not getting anywhere fast.  3 or 4 men could all be shoveling on one pile of coal for 30 minutes and not even make a noticeable dent in the pile.  That is why when I went to the tool room to choose a shovel, instead of picking a regular shovel, I picked a large scoop shovel used to scoop grain.

Scoop Shovel

Regular Shovel

Even though each scoop of coal was heavier, it seemed more satisfying to see the bigger dent in the pile of coal with each shovelful.  I remember one day after we had shoveled coal all day from morning until late at night only to come back into work the next morning to the new piles of coal just as big as the ones we had shoveled the day before.

After 2 years of volunteer coal cleanup which was becoming less volunteer and more rotational since the list of volunteers was growing smaller, Ray Butler pointed out that it didn’t make much sense to pay a first class machinist overtime to shovel coal when you could create a labor crew and pay them bottom dollar to do coal cleanup all the time, as well as other dirty jobs that no one really wanted to do (such as suck out sewage pits and other sump pits around the plant).

That was when the Labor crew was formed.  While I was in my 3rd year as a summer help (1981).  Bill Cook was a summer help then that stayed on as a labor crew hand at the end of the summer.  By the 4th summer as summer help, the only time we did coal cleanup was when there was a major spill, which was only a couple of times all summer.

I will write later about coal cleanup with Dale Hull.  I also remember doing coal-cleanup with Preston Jenkins one weekend.  I hadn’t carpooled with him to work, but I caught a ride back to Stillwater with him because my ride left at the end of a full day, and I decided to stay behind to add a few extra dollars to my bank account.  We left a couple of hours later around seven o’clock.

I climbed into the back of Preston’s Camaro.  I apologized for being so dirty, as I was covered from head-to-toe in coal-dust and my clothes were soaked with coal-dust permeated sweat.  Preston said that he didn’t mind.  I soon found out why.

When I climbed into the backseat of his car, I noticed that the upholstery that covered the seat back of the back seat was stained with some blackish-brownish um…. something.  Anyway.  I decided to sit on the passenger side of the back seat instead of behind the driver side because that side wasn’t nearly as stained.  As we drove down the highway toward home, I quickly learned why the seat back was so stained.

Being the “good-ol’ boy” that Preston was, when he climbed into the car, he took out his can of Skoal and put a pinch between his cheek and gums:

Just a pinch between your cheek and gums.... Never tried it myself.

Just a pinch between your cheek and gums…. Never tried it myself.

As we flew down the highway like a Texan heading for Stillwater, Preston would lean his head out the window and squirt out a wad of spit.  It would dance in the air like a little fairy just before it would be sucked into the back window of his car and splat against the seat back of the back seat.  Yep that explained it all right.  I always wondered if he knew, never having to sit in the back seat of his own car.

During the first summer when I was able to catch a ride with David Hankins a couple of times.  He was the crane operator at the time and drove a black Trans Am.  He was a black man with a very broad chest that never seemed to tire while doing coal cleanup.  From the first day he always treated me with great respect which in turn gave me a great respect for him.  I had him classified as a true Power Plant Man.

The second summer when I had been back at the plant for a couple of weeks, one day when Jim Heflin and I were going somewhere in a yellow Cushman cart, I asked Jim why I hadn’t seen David Hankins around.

A Cushman Cart Like this only Yellow

Jim (who hadn’t been at the plant the first summer) stopped the cart in the middle of the road and looked at me very solemnly and told me that David Hankins had died in a car accident in the spring.  He had been going home from a Men’s Club event when he was killed.  Because of this, alcoholic beverages were no longer allowed at Men’s Club events.  As with all the people I have worked with at the power plant, I keep David Hankins in my memory and I often think about him to this day.  David Hankins was a True Power Plant Man.

    We’ve lost so many friends over the years, in the plants and on the line, especially when they were relaxing on their way home. You, and David’s family have my 9very belated) condolences.

    Somebody, somewhere, needs to teach engineers a course on Conveyor Logic 101, I’ve seen the same thing happen in nearly every plant (from automotive, rarely, to meat packing, often) I’ve been in. Or they could, just for once in their life, shut their pie-hole and listen to people like you and me.

      Thanks Nebraska.

      We were often exhausted while driving home from work when we had been working a lot of overtime. It was a wonder sometimes that we were able to keep the car on the road.

      My uncle Bill Breazile worked for the Utility company in Nebraska City where someone closed a breaker while he was working on a line. He was in the hospital for about 6 months healing from his burns. This was about 30 years ago. He has since passed away. It takes a special person to be a lineman. Putting their life on the line every time they reach out to do their job.

        Not that different from you. It’s all about planning your work, and doing it right, and safely. You and I know that 480 will kill you just as quick as 7200 if you get careless. That’s why almost all (old) linemen and electricians are in some sense stolid and unexcitable.

    Industrial America returns in stories and comments in places like this, from the only place it still exists: the minds of those who were part of it. Industrial America was a giant; those who manned it were giant tamers and it seems to me, very much the special breed illuminated in these posts…

      I remember a time when I would have chose the bigger shovel, perhaps in the early 70’s. I was moving steel in a manufacturing plant. Carrying three bars on each shoulder seemed better than the two they suggested. We finished earlier, had to do other work, but somehow it felt better. Thanks for another interesting story and a wake-up call to younger days. Thanks also for the explanations. I love mechanical things and I get the impression that these plants are one big mechanical adventure.

Power Plant Painting Lessons with Aubrey Cargill

Originally Posted March 9, 2012.  I have added some pictures and slightly edited:

I had the feeling it would be an interesting day when the first thing that Stanley Elmore asked me when I sat down for our morning meeting was, “Kevin, are you afraid of heights?”  Well, since before that day I hadn’t been afraid of heights, I told him I wasn’t.  Then Stanley, who liked most of all to joke around with people, started hinting through facial expressions of excitement (such as grinning real big and raising his eyebrows up to where his hair line used to be when he was younger) and by uttering sounds like “boy, well, yeah…. huh, I guess we’ll see” while shaking his head as if in disbelief.  He told me to get with Aubrey after the meeting because there was a job I needed to help him out with.

Aubrey Cargill was our painter.  He worked out of the garage that I worked out of the last 3 years of working as a summer help.  There was a paint room in the back of the garage on the side where the carpenter, Fred Hesser built cabinets and other great works of art.  He was the best carpenter I have ever met, as well as one of the finest gentlemen I have ever known.  He wasn’t in the category of Power Plant man, as he didn’t involve himself in most of the power plant operations or maintenance, but to this day, Power Plant Men from all over Oklahoma can visit Sooner Plant on overhaul and admire the woodworking masterpieces created by Carpenter Fred many years earlier.

I had worked with Aubrey my first year as a summer help.  The garage hadn’t been built yet, and Aubrey had not been assigned as a painter, as both units were still under construction.  Aubrey was the same age as my father and in his mid-forties that first summer.  His favorite buddy was Ben Hutchinson.  Whereever one went, the other was not far away.  All during the first summer, the lake on the hill was still being filled by pumping water up from the Arkansas river.

Map of the Power Plant Lake

Map of the Power Plant Lake.  The power plant is on the northwest corner of the lake.  The Arkansas River is in the upper right corner of the map

Most of the last two weeks that summer I worked with Aubrey and Ben picking up driftwood along the dikes that were built on the lake to route the water from the discharge from the plant to the far side of the lake from where the water enters the plant to cool the condensers.  The idea is that the water has to flow all the way around the lake before it is used to cool the condenser again.  So, Ben and Aubrey took turns driving a big dump truck down the dike while I walked down one side of the dike around the water level and Aubrey or Ben walked down the other side, and we would toss wood up the dike into the dump truck.

A Ford Dump Truck

This was quite a throw, and often resulted in a big log being tossed up the dike just to hit the side of the dump truck creating a loud banging sound.  Anyway, when you consider that there are probably about 6 miles of dikes all together, it was quite a task to clean up all the driftwood that had accumulated in this man made lake.  After doing this for two weeks I learned the true meaning of the word “bursitis”.

After the morning meeting with Stanley Elmore I followed Aubrey into the carpenter shop, where he pointed to two buckets of paint that I was to carry, while he grabbed a canvas tool bag filled with large paint brushes and other painting tools and some white rope that looked like it had the seat of wooden swing on one end.  Aubrey nodded to Fred, and I understood by this that Fred had created the wooden swing that had four pieces of rope knotted through each of the corners of the seat and were connected to the main rope using some kind of small shackle.  When I asked Aubrey what that was, he told me that it is was a Boatswain Chair.  “Oh.” I think I said, “It looks like a swing.”

On the way to the boilers, we stopped by the tool room and I checked out a safety belt.  I could see Aubrey nodding at Bud Schoonover about my having to check out a safety belt, and what implication that had.  I of course preferred to think that my fellow employees would not purposely put me in harms way, so I went along acting as if I was oblivious to whatever fate awaited me.

We took the elevator on #1 Boiler to the 11th floor (which is actually about 22 stories up.  There are only 12 stops on the boiler elevator, but the building is really 25 stories to the very top.  So Power Plant men call the extra floors things like 8 1/2 when you get off the elevator where it says 8, and go up one flight of stairs.

Aubrey explained to me that we need to paint a drain pipe that is below us a couple of floors that goes down from there to just above floor 7 1/2 where it turns.  He said that he could paint the rest, but he needed my help to paint the pipe where it drops straight down, because there isn’t any way to reach it, except by dropping someone off the side of the boiler over a handrail and lowering them down to the pipe, and that turned out to be me.

He explained how the safety belt worked.  He said that I clip the lanyard in the ring at the top of the boatswain chair so that if I slip off the chair I wouldn’t fall all the way down, and then he could gradually lower me on down to the landing.  he didn’t explain to me at the time that the weight of my body free-falling three feet before coming to the end of the lanyard would have been a sufficient enough force to snap the white rope in half.  I guess he didn’t know about that.  But that was ok for me, because I didn’t know about it either — at the time.  We didn’t use Safety Harnesses at that time.  Just a belt around the waist.

So as I tied the canvas bag to the bottom of the chair, I saw Aubrey quickly wrap the rope around the handrail making some sort of half hitch knot.  I wasn’t too sure about that so I asked Aubrey where he learned to tie a knot like that and he told me in the Navy.  That was all I needed to hear.  As soon as he told me he learned knot tying in the Navy, I felt completely secure.  I figured if anyone knew the right way to tie a knot it’s someone in the Navy.

I clipped the lanyard in the shackle at the top of the boatswain chair and headed over the handrail.  I situated the chair to where I had my feet through it when I went over and the chair was up by my waist.  As I lowered myself down, I came to rest on the boatswain chair some 210 feet up from the ground.

It is always windy in this part of Oklahoma in the summer, and the wind was blowing that day, so, I began to spin around and float this way and that.  That continued until Aubrey had lowered me down to the pipe that I was going to paint and I was able to wrap my legs around it and wait for my head to stop spinning.

Then Aubrey lowered down another rope that had a bucket of paint tied to it.   Then I began my job of painting the pipe as Aubrey had hold of the rope and was slowly lowering me down.  Luckily Aubrey didn’t have to sneeze, or wasn’t chased by a wasp while he was doing this.  Thinking about that, I kept my legs wrapped around the pipe pretty tight just in case Aubrey had a heart attack or something.

The pipe really did need painting.  So, I knew this wasn’t completely just a joke to toss me out on a swing in the middle of the air hanging onto a rope with one hand while attempting to paint a pipe.  It had the red primer on it that most of the piping had before it was painted so it looked out of place with all the other silver pipes, but I couldn’t help thinking about Jerry Lewis in the Movie, “Who’s Minding the Store” where Jerry Lewis is told to paint the globe on the end of a flagpole that is located out the window on a top floor of the building, and he begins by trying to climb out on the flagpole with a bucket of paint in his mouth with little success.  But like Jerry, I figured it had to be done, so I just went ahead and did it.

Fortunately, I found out right away that I wasn’t afraid of heights, even at this height and under these conditions.  So, instead of fainting away, I just painted away and finally ended up on floor 7  1/2 which is right next to the Tripper Gallery.  I think I finished this a little after morning break but I don’t think Aubrey wanted to stop for break just to lower me down and then have to start from the top again lowering me all the way down one more time.

This brings me to another point.  Notice where I landed.  Right next to the Tripper Gallery.  Power Plant ingenuity has a way of naming parts of the plant with interesting names.  The first time I heard that we were going to the tripper gallery to shovel coal, I half expected to see paintings lining the walls.  It sounded like such a nice place to visit…. “Tripper Gallery”.  It sort of rolls off your tongue.  Especially if you try saying it with a French accent.

The Tripper Gallery is neither eloquent nor French.  It is where the coal from the coal yard is dumped into the Coal Silos just above the Bowl Mills.  — Yes.  Bowl Mills.  I know.  It sounds like a breakfast cereal.  Almost like Malt-O-Meal in a bowl.  So, the Tripper Gallery is a long narrow room (hence the word Gallery), and there are two machines called Trippers that travels from one silo to the next dumping coal from the conveyor belt down into the coal silo, and when the silo is full, a switch is triggered (or tripped) which tells the machine to go to the next silo.  Since the switch “trips” and tells the machine to move, they call the machine the “Tripper”.

 

Here is a picture of a clean tripper gallery I found on Google Images

I know.  That last paragraph didn’t have anything to do with painting the drain pipe.  But I thought since I mentioned the Tripper Gallery, I might as well explain what it is.  Anyway, when we returned to the shop I watched as Stanley Elmore went over to Aubrey to see how I did when I found out he was going to drop me over the side of the boiler in a wooden chair.  I could see that Aubrey gave him a good report because Stanley looked a little disappointed that this Power Plant Joke (even though essential), hadn’t resulted in visibly shaking me up.
