Power Plant Impossibilities or Processionary Caterpillars

The 77th “Rest Of” Power Plant Post

Originally posted 9/6/2014

I can remember four occasions while working at the Coal-fired Power Plant in North Central Oklahoma when I was told that something was impossible when I was already doing it. I mentioned two of those times in the posts “Toby O’Brien and doing the Impossible” and “Printing Impossible Fast News Post“. One day in May, 1992, I was asked to go to Oklahoma City to take some training.

There was a new kind of network that I was going to be responsible to create at our plant. During the training, I learned a little about how to hook up the RS-232 connectors to the Dumb Terminals I was installing throughout the plant. During the training, I also learned a lot about what was impossible.

I mentioned installing all the dumb terminals in an earlier post “Working Smarter with Power Plant Dumb Terminals“. I won’t go into the details about running the cables throughout the plant because I already covered that in the earlier post. What I would rather talk about is the narrow understanding at the time about the possibilities of networking instead of the impossibilities that I was learning by everyone that tried to teach me the laws of physics through common sense.

After I was done installing the terminals in the most obvious places, some people came and asked me if there was a way to install computer ports in some unlikely places. Some were sort of “out-of-the-way”. For instance, Phil Harden asked if I could install a network jack in the middle of the Bowl Mill area so that the Instrument and Controls team could wheel their portable Compaq computer out there and run diagnostics on the equipment while connected to the network.

I also installed a jack in the environmental controls shack out by Unit 1 smoke stack for Tony Mena. Of course, I installed one in the Precipitator Control Room since that’s where I worked a lot, and a computer hooked to the network came in handy more than once. I was always eager to run network cable and hookup computers. It was one of my favorite past times.

One time early in 1993, the A Foreman’s office was going to be renovated. It was going to take about a month or more for the construction, so all the foremen needed somewhere to stay when the office was going to be out of commission. Tom Gibson asked me one day how many computers and printers I could hook up in the conference room. I told him as many as he wanted. For one thing, it was only just down the hall from the Telephone room where the X.25 modems connected to the microwave transmitter on the top of Unit 1 Boiler.

Since this was going to be temporary, I didn’t want to mount a lot of network jacks all over the conference room… well, maybe a few…. The rest, I just strung down the wall from the ceiling. I think all together we had 8 computers and a printer installed in that room.

During this time, we had a new clerk come to the plant. This was a rare occasion because it was rare that anyone ever left the plant. Jana Allenbaugh (later Jana Haken) was our new clerk. She arrived on the first day when I had setup all the computers and everyone was moving out of the foremen’s office upstairs for their temporary stay.

I was just hooking up the printer, so I sent a long drawn out warning letter to the printer so that when I hooked it up in the Telephone room, it would start printing it out. I had done this before with Charles Patton… only, I don’t think Charles ever read what printed out…. See the post “Dick Dale and the Power Plant Printer Romance“.

This time I printed out a warning to Jana from the printer itself. it told her that as a new employee, she probably needed to know not to trust anyone who wears a yellow hard hat. They were not to be trusted. Because they treated printers with disrespect. Hardly noticing them, and only talking to them when their paper gets stuck. It went on from there, but that was about the gist of it.

Anyway. Up to this point, I haven’t pointed out the areas of impossibilities that I was performing against all advice from those who knew better.

You see in 1992, when I had attended the training course in Oklahoma City to teach me all about the finer aspects of hooking up RS-232 connectors, I was told that this technology had it’s limitations. The most important being the distance from the modem you can install a printer without having some sort of other switch to boost the signal.

I was installing network cable that at the time was called “Cat 1”. That was about the lowest grade wire you could use for data. Actually, it wasn’t even considered fit for data, just voice. Well. I was using it…. all the documentation said that when using Cat1, you had to be within 50 feet from the switch.

Well, in a plant where the control room was a good 100 yards (300 feet) from the telephone room, by the time you went up and down through ceiling, conduits, cable trays and wall, by the time the cable made it to the control room, it was at least 500 feet.

When running cable out to the shack by the smokestack I was able to use Cat 2 cable. This allowed a network cable to be around 500 feet long. When I ran this cable, it turned out to be longer than 1500 feet long. At least three times longer than the possible amount to run a network cable using this type of cable…. yet, I ran it, and Tony used it.

I know that if someone had asked Russell downtown at the Corporate Headquarters IT department, he would have said that this was as impossible as printing out the Fast News article on an IBM printer that I had printed out downtown. The truth was that there was a little data integrity lost by running a cable farther than possible by the laws of physics, but the system could easily handle the bad packets by resending them. The user never noticed that the connection was a little slower. No one ever complained that they couldn’t connect to the network.

A year after I had taken the initial training in hooking up network equipment, we learned all about the Quality process and how to think outside the box. See, “Power Plant Men have a Chance to Show Their Quality“. Between my father telling me that there is no word “Can’t” and Bob Kennedy saying that “I have a tool for that”, I had come to the conclusion that just about anything that needs to be done can be done. We just have to figure out how.

After we had taken the classes to learn about the quality process, one day I went to Ron Kilman’s office and I gave him a piece of paper. On it was a story about Processionary Caterpillars. It was significant, I thought, because it demonstrates what happens when people refuse to thing “outside the box”. The story goes like this:

Processionary Caterpillars feed upon pine needles. They move through the trees in a long procession, one leading and the others following – each with his eyes half closed and his head snugly fitted against the rear extremity of his predecessor.

Jean-Henri Fabre, the great French naturalist, after patiently experimenting with a group of the caterpillars, finally enticed them to the rim of a large flower pot. He succeeded in getting the first one connected up with the last one, thus forming a complete circle, which started moving around in a a procession, with neither a beginning nor end.

The naturalist expected that after a while they would catch on to the joke, get tired of their useless march and start off in some new direction. But not so….

Through sheer force of habit, the living, creeping circle kept moving around the rim of the pot – around and around, keeping the same relentless pace for seven days and seven nights – and would doubtless have continued longer had it not been for sheer exhaustion and ultimate starvation.

Incidentally, an ample supply of food was close at hand and plainly visible, but it was outside the range of the circle so they continued along the beaten path.

They were following instinct – habit – custom – tradition – precedent – past experience – standard practice – or whatever you may choose to call it, but they were following it blindly.

They mistook activity for accomplishment. They meant well – but went no place.

This post may seem like I am doing some bragging about my ability to think outside the box. My personality may be more apt to brag about my accomplishments than to recognize that everything I do and know is a gift from God. But in this case there is more to it than that. You see, even though my grandfather who was a sharecropper who worked his entire life farming land that didn’t belong to him, he was able to invent equipment to make his life easier. He could look at something in a catalog and build it…. I didn’t inherit this gene. I had to learn this way of thinking.

I used to get in arguments all the time at the power plant because I believed that I could do things that were equivalent to walking on water. It drove the engineers mad… Actually, they were mad all right, but just at me… not in their minds…. Why was I so sure? I had been trained by the best.

If you have been reading my blog for the past two and a half years, you will know what I’m talking about…. I was trained by the best to think outside the box. To Power Plant Men, the Quality process was not a way to find out how to come up with quality ideas…. it was just a way to demonstrate what they already knew in a way where the Engineers and management could understand the benefit.

Here are some of the Power Plant Men that taught me the most about thinking outside the box:

Larry Riley, who taught me that you really can play music by the way you operate a backhoe.

Ken Conrad, who taught me that no matter how complicated a task, by breaking it down into simple steps, it is as simple as “Sweet Pea”.

Jim Heflin, who taught me that when all else fails, shake your head and say to yourself… “Well…. there it is…. let’s try that again a different way….”

Andy Tubbs who taught me that if you think you’re so smart that you don’t need to learn anymore, then it’s time you take out the blueprints and study it some more.

Floyd Coburn taught me that when it really looks hopeless, then prayer is always the best option.

Ed Shiever taught me that when you are extremely kind to your fellow man, when things begin to fail, everyone will come to your aid.

Earl Frazier taught me that your memories will keep you loving those important to you long past the time when those people are lovable.

Kent Cowley taught me that you can still be a gentleman even when you are a boiler rat.

Mike Crisp taught me to look to the heavens in order to really understand the metal being shaped into a part by a lathe.

Bill Thomas taught me that loyalty to your fellow Power Plant Men comes from within your own heart, and not the actions of others.

Timothy Crain taught me that everything you do is for your family, no matter what situation they may find themselves.

Dale Mitchell taught me that personal integrity allows you to open your heart to even the most difficult people.

Juliene Alley taught me that one person can be everyone’s Mother when they are pure in heart.

Jerry Dale taught me that the more complicated the puzzle, the more humor will unravel it.

Bob Rowe taught me that simplicity makes more sense than trying to make things complicated.

I have listed a few (and only a few) of the Power Plant Men that as an accumulation, taught me to think outside the small box that I was in 1979 when I first arrived as a Power Plant Summer Help until 2001 when I left to begin a new career as an IT professional (ouch… what a run-on sentence). This allowed me to think outside the box. I never would have made it to that position if it hadn’t been for the wonderful men and women who led me by the hand… sometimes kicking and screaming to the lid of the box so that I could peer outside and imagine other possibilities.

      Kev, as you know we had just an incredible , amazing group of talent at the plant , and for the most part a group that to along with each other and looked out for each other too.
      I still think about all those guys and all that collective intelligence among them, truly truly a blessing.

      Facet: a part or element of something.

      God is “omni-facetted” (new word) = He has infinite facets. Since each person is His unique creation, we each are born with our own unique manifestation of a part of God. You have learned to look for, recognize, and honor that in people. I think this is your best post yet.

Taking Power Plant Safety To Task

The 76th “Rest Of” Power Plant Post

Originally posted August 9, 2014

One of the phrases we would hear a lot at the coal-fired Power Plant in North Central Oklahoma was “Safety is Job Number One”. It’s true that this should be the case, but at times we found that safety was not the highest priority. It is easy to get caught up in the frenzy of a moment and Safety just seemed to take a second row seat to the job at hand.

Making Safety Job Number Two was usually unintentional, but sometimes on rare occasions, we found that it was quite deliberate. Not as a company policy, but due to a person’s need to exert their “Supervisory” Power over others. I mentioned one case in the post titled: “Power Plant Lock Out Tag Out, or Just Lock Out“.

During the summer of 1993, everyone at the plant learned about the Quality Process. I talked about this in the post: “A Chance for Power Plant Men to Show Their Quality“. I had joined the Action Team.

This was a team of Power Plant Men and Women that reviewed proposals turned in by the quality teams in order to determine if they had enough merit to be implemented. If they did, we would approve them. If we decided an idea was not appropriate enough to be implemented, we sent it back to the team that had written the proposal with an explanation why it was rejected.

Our team had turned in a proposal to create a Safety Task Force. One that would act like an Action Team similar to the one formed for the Quality Process. It seemed like a logical progression. I was the main proponent of the Safety Task Force, but to tell you the truth, it wasn’t all my idea.

Not only had other members of our Quality Team mentioned forming a Safety Task Force, but so did our Electric Supervisor, Tom Gibson. He had called me to his office one day on the pretense of me getting in trouble…. I say that, because whenever he would call me on the gray phone and respond, “Kevin. I want to see you in my office right now.” that usually meant that I had stepped on someone’s toes and I was in for a dressing down…

Gaitronics Gray Phone

— Was I the only one that had this experience? It seemed that way. But then, I was usually the one “expanding my bubble” (as Charles Foster would say). When I arrived at Tom’s office, he asked me if I would ask our team to create a proposal for a Safety Task Force. I told him that I’m sure we would. We had already talked about it a couple of times in our meetings.

I didn’t mind playing “Bad Cop” in the game of “Good Cop, Bad Cop”. That is, it never bothered me to be the one that pushed an unpopular issue that really needed pushing. Where someone else would follow-up as the “Good Cop” in a way that takes away the bitter taste I left as “Bad Cop” by proposing the same solution I proposed only with a more positive twist.

At the time, I figured that Tom Gibson was going to be “Good Cop” in this effort since he had pulled me aside and asked me to initiate the proposal. As it turned out, I ended up playing both Bad Cop and Good Cop this time. I played the Good Cop when Ron Kilman had met with me to discuss a new Safety Idea. The Behavior-Based Safety Process. See the Post: “ABC’s of Power Plant Safety“.

I proposed the Safety Task Force in a sort of “Bad Cop” negative manner. That is, I had pointed out how our current system was failing, and other negative approaches. When I explained how the Behavior-Based Safety Process works as “Good Cop”, Ron had told me to go ahead and form the Safety Task Force.

I asked for volunteers to join the Safety Task Force. After I received a list of people that wanted to be on the Task Force, I chose a good cross-section of different roles and teams from both Maintenance and Operations. I had lofty visions of telling them all about the Behavior-Based Safety Process, and then going down the road of implementing this process at the plant.

I didn’t realize that the Power Plant Men had different ideas about what a Safety Task Force should be doing. They weren’t really interested in trying out some new Safety “Program”. I tried explaining that this was a “Process” not a “Program”, just like the Quality Process. They weren’t buying it.

We had Ground Rules that we created the first day that kept me from ramming anything down their throats, so I went along with the team and listened to their ideas. It turned out that even though the Power Plant Men on the Safety Task Force didn’t want to hear about my “beloved” Behavior-Based Safety Process, they did have good ideas on how to improve safety at the plant.

We decided that we would ask for Safety Proposals just like the Quality Process did. It was felt that the Safety Task Force didn’t have any real “authority” and a lot of people at the plant thought that without the authority to really do anything, the task force was going to be an utter failure.

We decided that the best way to show that the Task Force was going to be a successful force of change toward a safer Power Plant, we would ask for ideas on how to improve the safety at the plant. When we did, we were overwhelmed by the response. Safety Concerns poured in from all over the plant.

At one point we had over 250 active safety ideas that we had decided were worth pursuing. The members of the team would investigate the ideas assigned to them and see what it would take to make the requested changes. Because of the overwhelming response, it didn’t make much sense taking all the approved requests to the Plant Manager. So, in many cases, we decided that a trouble ticket would be sufficient.

I posted the progress of all the active ideas each week on every official bulletin board in the plant. This way, everyone could follow the progress of all of the ideas. As they were successfully completed, they went on a list of Safety Improvements, that I would post next to the list of active proposals.

I think the members of the Safety Task Force might have been getting big heads because at first it appeared that we were quickly moving through our list of plant Safety Improvements. A lot of the improvements were related to fixing something that was broken that was causing a work area to be unsafe. I say, some of us were developing a “big head” because, well, that was what had happened to me. Because of this, I lost an important perspective, or a view of the ‘Big Picture”.

I’ll give you an example that illustrates the “conundrum” that had developed.

We had created some trouble tickets to fix some pieces of equipment, and walkways, etc, that posed a safety risk. After several weeks of tracking their progress, we found that the trouble tickets were being ignored. It seemed that this came on all of the sudden. When we had first started the task force, many of our trouble tickets were being given a high priority, and now, we were not able to succeed in having even one trouble ticket completed in a week.

After going for two weeks without one of the trouble tickets being worked on, I went to Ron Kilman, the Plant Manager to see if we could have some of his “Top Down” support. To my surprise, he gave me the exact same advice that our Principal, Sister Francis gave our Eighth Grade class at Sacred Heart School in Columbia, Missouri when we ran to her with our problems.

Ron Kilman

Ron Kilman – He looks nothing like Sister Francis

Ok. Side Story:

Three times when I was in the eighth grade, our class asked Sister Francis to meet with us because we had an “issue” with someone. One was a teacher. We had a personal issue with the way she conducted herself in the class. Another was a boy in the 7th grade, and the fact that we didn’t want him to go with us on our yearly class trip because he was too disruptive. The third was a general discontent with some of the boys in the 5th and 6th grade because of their “5th and 6th grade” behavior.

In each case, Sister Francis told us the same thing (well almost the same thing). In the first two cases, she told us we had to handle them ourselves. We had to meet with the teacher and explain our problem and how we wanted her to change. We also had to meet with the boy in the seventh grade and personally tell him why we weren’t going to let him go on our trip. In each case it was awkward, but we did it.

In the case of the 5th and 6th graders, Sister Francis just said, “When you were in the 5th grade, if you acted the way these 5th graders acted to an eighth grader, what would happen? Well. Deal with this as you see fit. We all knew what she meant. When we were in the fifth grade, if we treated the eighth graders the way these guys treated us, they would have knocked us silly.

So, the next morning when I was approached by a fifth grader displaying the disrespectful behavior, I gave him a warning. When my warning was greeted with more “disrespect”, I did just what an eighth grader would have done when I was a fifth grader. I pushed him down the stairs. — Not hard. He didn’t tumble over or anything, but he ran straight to Sister Francis and told her what I had done.

Sister Francis came up to our room and told me to go to the principal’s office. — We only had 14 people in the Eighth Grade, so it wasn’t hard to find me. I protested that I was only doing what she authorized us to do the previous day. She agreed, but then she also explained that she had to respond the same way she would have responded to the eighth graders three years earlier if they had done the same thing.

I could tell by her expression, that my “punishment” was only symbolic. From that day on, the 5th and 6th graders that had been plaguing our class were no longer in the mood to bother us. We had gained their respect.

End of Side Story.

So, what did Ron Kilman tell me? He told me that if we were going to be a successful Safety Task Force, then we would need the cooperation of Ken Scott. Ken was the Supervisor of the Maintenance Shop and the one person that had been holding onto our trouble tickets. Ron said, “You will have to work this out with Ken yourself.” — Flashes of Ron Kilman wearing a black nun’s robe flashed through my head, and suddenly I felt my knuckles become sore as if they had been hit by a ruler. — No, I’m not going to draw you a picture.

So, we did what would have made Sister Francis proud. We asked Ken Scott to meet with us to discuss our “issue”. We pointed out to him that the trouble tickets we had submitted were safety issues and should have a higher priority. We also pointed out that we had not had one safety related trouble ticket completed in almost three weeks.

Then it was Ken’s turn…. He said, “Just because you say that something is a safety issue doesn’t make it one. Some of the trouble tickets submitted were to fix things that have been broken for years. I don’t think they are related to safety. I think people are using the safety task force to push things that they have wanted for a long time, and are just using “safety” as a way to raise the priority. Some of these ideas are costly. Some would take a lot of effort to complete and we have our normal tickets to keep the plant running.” — Well, at least when Ken stopped talking we knew exactly where he stood. He had laid out his concerns plain and clear.

The Safety Task Force members used some of the tools we had learned during the Quality Process, and asked the next question…. So, how do we resolve this issue? Ken said that he would like to be consulted on the ideas before a trouble ticket is created to see if it would be an appropriate route to take.

It was obvious now that we had been stepping all over Ken’s Toes and our “demands” had just made it worse. Ken felt like we had been trying to shove work down his throat and he put a stop to it. After hearing his side of the story, we all agreed that we would be glad to include Ken in all the safety issues that we thought would require a trouble ticket.

From that point, we had much more cooperation between Ken Scott and the Safety Task Force. Ken really wasn’t a problem at all when it came down to it. The way we had approached the situation was the real issue. Once we realized that, we could change our process to make it more positive.

One Barrier Down

One Barrier Down

This worked well with Ken, because he was forthright with us, and had spoken his mind clearly when we asked. This didn’t work with everyone of the people that pushed back. We had one person when we asked him if he could explain why he was blocking all our attempts to make changes, his only reply was “Because I am the barrier! I don’t have to tell you why!” That is another story. I’m not even sure that story is worth telling. I know that at least one person that reads this blog regularly knows who I am referring to, because he was in the room when this guy said that…. He can leave a comment if he would like….

ABC’s of Power Plant Safety

The 75th “Rest Of” Power Plant Post

Originally posted August 2, 2014

Scott, Toby and I were all sitting in the front seat of Scott’s pickup truck on our way home from the coal-fired power plant in North Central Oklahoma, because this particular pickup didn’t have a back seat. I guess that’s true for most pickup now that I think about it. It was in the fall of 1993 and I was on one of my rants about Power Plant Safety (again).

Scott Hubbard was focusing on the road and he was smiling. I think it was because the person that was talking on NPR (National Public Radio) had a pleasant voice.

Scott Hubbard

Come to think of it… Scott was usually smiling.

I was going on and on about how the plant needed to take a completely didn’t approach to safety. I thought that we just looked at each accident as an isolated case and because of that we were missing the point. The point was that no one really goes to work with the idea that they want to do something that will hurt them. Power Plant Men in general don’t like having accidents. Not only does it hurt, but it is also embarrassing as well. Who doesn’t want that 20 year safety sticker?

I worked 20 years without an accident

I was in the middle of my safety rant all prepared to continue all the way from the plant to Stillwater, about 20 miles away when Toby quickly interrupted me. He said that he had received a safety pamphlet in the mail the other day that was saying the same things I had just said. It had talked about a way to change the culture of the plant to be more safe. Not using the same old techniques we were used to like Safety Slogan Programs (I was thinking…. but what about the Safety Slogan Pizza award at the end of the year? Would that go away? See the Post: “When Power Plant Competition Turns Terribly Safe“). Toby said that he read it and then set it aside as just another one of the many safety sales pitches a Plant Engineer might receive in a week.

Power Plant Engineer and Good Friend - Toby O'Brien

Power Plant Engineer – Toby O’Brien

Toby said he only remembered the pamphlet because I had just made a statement that was word-for-word right out of the safety pamphlet. I had said that the only way to change the Power Plant Safety Culture was to change the behavior first. Don’t try to change the culture in order to change the behavior. When I had earned my degree in Psychology years earlier, I had been told by one of my professors that the area of Psychology that works the best is Behavioral Psychology.

To some, this might sound like treating the symptoms instead of the actual cause of a problem. If your not careful that may be what you end up doing and then you ignore the root of the problem, which brings you back to where you were before you tried to change anything in the first place. Toby said he would give the pamphlet to me the next day.

So, the rest of the ride home was much more pleasant. Instead of finishing my rant about Safety, we just listened to the pleasant voices on National Public Radio. I was excited about the idea that someone might have a solution that I believed offered the best chance to change the direction of Safety at the plant away from blaming the employee, to doing something to prevent the next accident.

The next day, after we arrived at the plant, I made my way up to the front offices to Toby’s desk so that he could give me the safety pamphlet he had mentioned on the ride home. When he gave it to me, the title caught my eye right away. It was a pamphlet for a book called: “The Behavior-Based Safety Process, Managing Involvement for an Injury-Free Culture”. Now I was really excited. This sounded like it was exactly what I had been talking about with Toby and Scott. I sent off for the book right away.

When the book arrived I wanted to climb on the roof of my house and yell “Hallelujah!” I was suddenly one with the world! As I read through the book my chin became chapped because my head was nodding up and down in agreement so much that the windy draft caused by the bobbing motion chafed my chin.

I finished the book over the weekend. When I returned to work on Monday, I wrote another quick letter to the Plant Manager, Ron Kilman and the Assistant Plant Manager, Ben Brandt telling them that I would like to discuss an idea for a new safety program…. um…. process. Process is better than Program… as we learned in Quality Training. A process is the way you do something. A program is something you do, and when it’s over, you stop doing it.

Later that week, I met with Ron Kilman, Ben Brandt and Jasper Christensen in Ben’s office.

Ron Kilman

Ron Kilman

I had just read the book for the second time, I had already had 5 dreams about it, and I had been talking about it non-stop to Charles Foster and Scott Hubbard in the electric shop for days. So, I felt confident that I was prepared for the meeting. I still remember it well.

Ron asked me to explain how this new process would work and so I started right in….

In order for this process to work, you have to understand that when an accident occurs, it is the system that is broken. It isn’t the employee’s “fault”. That is, the employee didn’t wake up in the morning thinking they were going to work today to have an accident. Something went wrong along the way, and that is what you have to focus on in order to improve safety. Not so much the employee, but the entire system.

If people are unsafe, it is because “The System” has trained them to work unsafe (for the most part…. — there will always be someone like Curtis Love…. accidents sometimes traveled 45 miles just to attack Curtis Love).

The trick is to identify the problems with the system, and then take steps to improve them. Ben was nodding as if he didn’t quite buy what I was saying. Ron had looked over at Ben and I could tell that he was skeptical as well (as I knew they would, and should be…. I had already demonstrated that I was a major pain in the neck on many occasions, and this could have been just another attempt to wreak havoc on our plant management). So Ron explained a scenario to me and asked me how we would go about changing the system to prevent these accidents in the future….

Ron said, Bill Gibson went down to work on the Number 1 Conveyor Belt (at the bottom of the dumper where the coal is dumped from the trains).

Bill Gibson

Bill Gibson

While he was down there, he noticed that some bolts needed to be tightened. The only tool he had with him that could possibly tighten the bolts was a pair of Channel Locks.

 

Channel Locks

Channel Locks

All of us had a pair of Channel Locks. One of the most Handy-dandiest Tools around.

Ron continued…. So, instead of going back to the shop and getting the correct size wrench to tighten the bolts, Bill used the channel locks to tighten them. He ended up spraining his wrist. Now how are you going to prevent that?

I replied…. One of the most common causes for accidents is using the wrong tool. There are usually just a few reasons why the wrong tool is used. If you fix those reasons, then you can prevent this from happening. The main and obvious reason why this accident occurred was because the right tool wasn’t there with him. This could be fixed a number of ways. Bill and his team could have a small bag that they carry around that had the most likely tools they might need for inspecting the conveyors. They might have another bag of tools that they use when they need to go inspect some pumps… etc.

Another solution may be to mount a box on the wall at the bottom of the dumper and put a set of wrenches and other important tools in it. If that box had been there and Bill had found the loose bolts, he only would have to walk a few feet to get the right tool instead of trudging all the way back up to the shop and then all the way back down.

It wasn’t that Bill didn’t want to use the right tool. He didn’t want to bruise his wrist. He just wanted to tighten the bolts.

— This had their attention… I was able to quickly give them a real action that could be taken to prevent a similar accident in the future if they would take the effort to change the “System”. Even Ben Brandt leaned back in his chair and started to let his guard down a little.

This was when I explained that when someone does something, the reason they do it the way they do is comes down to the perceived consequences of their actions…

We were always being drilled about the ABC’s of First Aid from Randy Dailey during our yearly safety training. That is when you come across someone lying unconscious, you do the ABC’s by checking their Airway, the Breathing and their Circulation. I introduced Ron, Ben and Jasper to the ABC’s of Safety. Something completely different. The ABC’s of Safety are: Antecedents, Behavior and Consequences.

An Antecedent is something that triggers a particular behavior. In Bill’s case, it was finding the loose bolts on Conveyor 1. It triggered the behavior to tighten the bolts. Bill chose to use the wrong tool because the correct tool was not immediately available, so he weighed the consequences. The possible behavior choices were:

  • I could use the pair of channel locks here in my pocket.
  • I could spend the next 20 minutes climbing the 100 feet up out of the dumper and go over to the shop and grab a wrench and walk all the way back down here.
  • I could leave the bolts loose and come back later when I have the right tool.

The consequences of these behaviors are:

  • I could be hurt using the channel locks, but I haven’t ever hurt myself using them before, and the chances are small.
  • I could be late for lunch and I would be all worn out after climbing back up to the shop. The chances of me being all worn out by the time I was done was very high.
  • The loose bolts could fail if I waited to tighten them, and that could cause more damage to the equipment that would cause a lot more work in the future. The chance of this is low.

The behavior that a person will choose is the one that has an immediate positive consequence. If the odds of being hurt is small, it will not stop someone from doing something unsafe. Also, if the negative consequence is delayed, it will not weigh in the decision very highly. Positive consequences outweigh negative consequences.

So, in this case, the obvious choice for Bill was to use the channel locks instead of going back to get the right tool.

When I finished explaining this to Ron and Ben, (Jasper was nodding off to sleep at this point)… Ben asked where I came up with all of this. That was when I reached down and picked up the book that was sitting in my lap. I put it on the table. I said, I read about it in here:

Book about the Behavior-Based Safety Process

Book about the Behavior-Based Safety Process by Thomas Krause

Ben grabbed the book and quickly opened up the front cover and saw that I had written my name inside the cover. He said, “It’s a good thing you put your name in here or you would have just lost this book.” I told him he could read it if he wanted.

Ron said that he would consider what I had said, and a few day later he responded that since I had been requesting that we start up a Safety Task Force to address the plant safety concerns that he would go ahead and let us start it up, and that he wanted us to consider starting a Behavior-Based Safety Process in the future. — That will be another story…

Let me finish this post with a warning about the Behavior-Based Safety Process…

In order for this to work, it has to be endorsed from the top down, and it has to be implemented with the understanding that the employee is not the problem. Punishing employees for working unsafe will destroy any attempt to implement this process properly.

Training everyone is essential. Especially management. I can’t emphasize this enough. In order to produce an accident-free culture, everyone has to keep it positive. Any changes in the system that helps prevent accidents is a good thing. Any unsafe behavior by an employee is a symptom that there is something wrong with the system that needs to be addressed. — Reprimanding an employee is destructive… unless of course, they intentionally meant to cause someone harm. — But then, they wouldn’t really be Power Plant Men, would they?

The phrase was: 'Cause I Love You Man!

The phrase was: ‘Cause I Love You Man!

      My father always made a box or a rack so that every tool needed to adjust something like a table saw was always attached to that saw. I do the same thing.

      I really enjoyed your post. I’ve never worked in a power plant (no hand eye coordination, for one thing), but the challenge of convincing management to focus on safety and change an existing procedure is universal. Best wishes!

      Great post. I worked at a Ford UAW plant for 28 years. We finished out with four years without a lost time injury – this plant was heavy machining manufacturing automotive steering gears so we had a lot of heavy equipment everywhere. Walking out the door the same way and with the same body parts you came in with will be our greatest legacy!

    I’m the power plant night shift foreman with 31 accident free years, yet my hardhat sticker says 26 years, so I went to our safety guy to find out why the “sticker” program had been dropped. He did some research & found out that about a half dozen years ago, corporate accountants did a cost/benefit analysis of our hardhat safety stickers & could see no “profit” in it

Power Plant Imps and Accident Apes

The 74th “Rest Of” Power Plant Post

Originally posted: July 26, 2014:

In order to promote Safety at the coal-fired Power Plant in North Central Oklahoma in 1988, we watched a video that introduced us to the four “Imps”. These were little creatures that lurked around the power plant waiting to cause accidents. The video demonstrated how these four imps had led a racing car to have an accident which put the driver in hospital. The Imps were called: Impatience, Improvisation, Impulsiveness and Impunity.

The video also went on to say that “Knowing is not enough”. You have to “Act” on what you know. The four imps try to keep you from acting when you know that there is a safe way to do something. A Yellow Flag was used in the video when the crash occurred during the race, and the video went on to emphasize that if we could only see the Yellow Flag “Before the accident happens”, then we could take steps to prevent it. In order to do that, you first have to eradicate the four imps. We were given Hard Hat stickers to remind us to look for accidents before they happened:

See the Yellow Flag Before the Accident Happens

See the Yellow Flag Before the Accident Happens

Before I tell you about the Apes, let me just briefly go over these four imps and how they interfere with a safe work environment….

Impatience may be obvious. Getting in a hurry causes us to take short cuts and not think things through. This Imp works with all the other imps to lead us to engage in unsafe behavior.

Improvisation happens when you don’t have the right tools handy or the proper safety equipment isn’t easily accessible. It may also happen when the right parts aren’t right there when you need them. So, instead of taking the time to go get the right tools for the job, or the right part to fix an issue (with the help of Impatience), we Improvise. Leading to taking unnecessary risk.

Impulsiveness comes around when when we act without thinking. We react immediately to a situation without thinking about it. Maybe because we think that we are so experienced that our instincts serve us better than our brains. Again, Impatience is right there urging us on to act Impulsively.

I think one of the Monthly Safety Slogans we turned in when we were trying to win the yearly Safety Slogan pizza (see “When Power Plant Competition Turns Terribly Safe“) was “Acting Impulsive can leave you pulse-less”.

Impunity is a stealthy imp (unless you are young… then it is a way of life). This is the believe that you are impervious to being hurt. You think you are either very lucky (which I know “I am”), or you are so experienced at your job that you will not be hurt even when doing things you know are unsafe.

We had a safety campaign at the plant to “Look for the Yellow Flag” and “Beware of the Imps”. I thought it was a good reminder to be safe, especially since most of us had been working at the plant for a number of years and needed to be reminded that we were not impervious to the four imps. This was an honest attempt to keep us from becoming complacent with our own safety.

Four years later, however, the accident rate at our plant had reached a nine year high and having the big mouth that I was born with, I had to say something about it. So, I wrote a letter to our plant manager voicing my concerns.

In the letter I suggested that we should brainwash our employees to work safely. I will discuss how to do this in a later post. I suggested that brainwashing our employees to work safely would be best because when someone is brainwashed they are not allowed “by the fact that they are brainwashed” to think “outside the box”. In other words, someone that is brainwashed to work safely is not able to function “unsafely”.

I had studied brainwashing techniques when I was in college after I had attended a meeting with my roommate one day and within an hour I had been brainwashed by the Southwest Book Publishing Company to think that the only thing I could possibly do next summer was sell books door-to-door. I really believed that not only was selling books door-to-door my only option, but that there was no way I could do anything else.

After my mom had slapped me around (not literally) until I snapped out of it, I became fascinated by how easily it was to become brainwashed. So I decided to study it in order to prevent that from happening again. I even changed my major to Psychology, because of that experience.

I learned that there are five main techniques used to brainwash someone. Most of these are the same techniques used by good salesmen to sell you products you wouldn’t normally want to buy. Those that would be best used to brainwash an employee to be safe are: Repetition, Role-playing, Cognitive Dissonance and Commitment.

The Fifth brainwashing tool is “Fatigue”. But in order to do that, you would have to put the person in a closet and beat them with a rubber hose any time they think about doing something unsafe. Even though this sounds exciting, the only place in the plant that would suffice was the janitor closet in the main switchgear, and then you could only use it on one Power Plant Man at a time.

Like I said, I’ll explain how to brainwash employees to work safely in a later post. I will expand a little on “Cognitive Dissonance” since I mentioned it and it isn’t as common known as the rest of the tools. Cognitive Dissonance occurs when your mind detects that there is something not exactly right with the logic of something so, a person changes their belief to remove this “Dissonance” (or Discord in your brain).

A person with very good argument skills is sometimes known as an “Apologist”. That is someone that can make a good clear argument for something by building on one argument after the other until the other person can clearly see and believe what the Apologist is trying to convince them. You see this a lot with religious groups.

In fact, when I went away to college, and just before I had been brainwashed by the Southwest Book Publishing Company, my mother had told me “Don’t let yourself be brainwashed by some religious cult.” I said “Sure Mom.” — Being on the lookout for this, I never suspected that when my roommate asked me if I wanted to go along with him to listen to someone talk about summer jobs for next summer, I was going to be so easily brainwashed by a book publisher.

Anyway, back to Cognitive Dissonance…. When you are trying to Brainwash someone to believe something they do not already believe, you do this through a series of carefully crafted statements in order, that the other person needs to agree to before you go to the next one.

Each statement introduces a small cognitive dissonance, or a “challenge” to the person’s reasoning that they have to reconcile in their mind. They are not given much time to do this, and through the use of repetition and role-playing, a person is more likely to accept that small change in their belief in order to avoid the dissonance they are experiencing.

By the time the person reaches the end, if they have agreed to each of the statements then it comes time for the “Commitment”. They sign something, or they go through some initiation, or something that seals their “fate”. Then they believe that they have no other choice but to go down that path.

Here’s an example:

After I had learned about these techniques in college, I thought it would be neat to see them in action, so I made an appointment with an Insurance Salesman. Who better? I went to his office and told him that I was thinking of buying some life insurance. So, he began his “sales pitch”.

Throughout the conversation, I was watching how he was using leading statements that I was agreeing to one at a time. “Yeah… makes sense to me” I would say… When he was finished I was surprised by the way he pulled out a sheet of paper and said, “Sign here.”

Not having actually been brainwashed by the person, since I was too busy thinking about his techniques, I was amazed by how sure he was that I was all ready to sign up for life insurance right there on the spot. — I told him I would think about it and left. I even remember his name… Chuck Farquar. That was too good of a name to forget.

Anyway, time for the Power Plant Apes:

In 1993, I wrote another letter to our plant manager Ron Kilman (I liked writing letters… or Memos… I guess you could call them). In this letter I mentioned that I thought the program that introduced us to the four Imps was pretty good, and that we needed something like that again because not only were the four Imps still lurking about, but so were five Apes! I had found that there were five Apes running around the plant wreaking havoc.

I explained that the Five Apes were: Apathy, Apprehension, Apishness, Aplomb and Apostasy. I had noticed these five Apes popping up around the plant helping the four imps cause accidents.

Apathy is “Not Caring”. Not only Not Caring for our own safety, but not caring for the safety of others. This could be seen when people didn’t clean up their work area when they were done. A lack of pride in their Safety attitude.

Apprehension occurred when someone was too afraid to speak up when they saw safety issues. Either because they thought others might not agree with them, or because they had spoken up in the past and had their hand slapped for making a fuss. Either way, I could see unsafe conditions that were left unchecked because people didn’t want to mention them.

Apishness is when someone “Apes” another person’s behavior. Peer Pressure leads to this. They imitate them. One person sees another person working unsafely and instead of pointing it out to them, they see that they are getting away with it, so, they decide to do their work in the same unsafe manner. — This is sort of like Cognitive Dissonance working toward brainwashing someone to work unsafe.

Aplomb is having self-confidence. Though this sounds like a good trait to have, when you are working around dangerous equipment all the time, self-confidence is a killer. When I was teaching my son to drive a car, I told him that as soon as he feels comfortable driving a car, then he should know, that’s when he has become the most unsafe. He doesn’t have the experience to automatically react in a safe way, yet, he believes that he knows what he is doing so he lets his guard down.

Apostasy is the belief in a “heresy”. When dealing with Safety, it is the belief that being Safe is not important. The thought that fate is not even in my hands. — I hear this when someone says, “You only live once.” Doris Day used to say this when she sang the song: “Que Sera Sera” — What will be will be…

In case you can’t play a You Tube video from that link on your old outdated computer… here is the link: “Doris Day singing Que Sera Sera“.

I could see that some people at the plant had reached the point of discouragement to where they believed that all the talk about safety had gotten us no where. People still had accidents at the same rate as before… When we tried to improve safety it never seemed to work. So they just gave up on the process.

With all these Imps and Apes running around the plant is was a wonder we were ever able to get any work done! There is more to come on this topic…

      Then there was BBS – Then there is IIF and hiring of Safety Professionals to prosecute and punish anyone that gets ticketed its a double edged sword those that have personality conflicts with others and who being marginal at their job play the safety card over and over , hence costing a lot of time and money on needless wild goose chases. Cell Phones are a distraction in the plant I agree, however, there productivity improvement outweighs the negative side of them. A person with a cell phone can report someone in danger or alert everyone to problems when we lost the plant our only means of communication was cell phones to the outside world and they acted both as first line and backup during the crisis inside the plant as well. A friend told me once when we start fearing and focusing on that fear is when it will happen I remember making us all write letters to our wives and sad to say about a year later OGE Power Supply lost a fine man, with all the programs and focus we lost that man- with all the engineers in the ivory tower we could not learn that if a gasket continuously leaks at different times that either we have a warped surface due to improper warmup methods or we have a faulty gasket and that we never tighten those on a high pressure vessel under operating conditions we blamed the gasket but the gasket was known many times over but yet we failed to find a solution until the unthinkable happened and accountability all the people in charge and so forth still have their jobs they knew they had problems with it thats why knowing is not enough!
      That’s why you cannot take people without experience in the trenches and put them in jobs that they have not learned up through the ranks you cannot capture and replace an individual with anyone from any old bar! I still think the Managing Director all the way down through the Operating /Maintenance Superintendents should have been held accountable feeling bad and sorry does not bring that fine man back! In operations we are drilled over and over and over about it how our mistakes cost lives and arms and legs etc and we will have error free switching Man is not perfect and never will be his nature will never let him be! and with all the education in the world we still have not learned this! They knew the drum head for the access door and or the gasket was bad and especially if you have had an acid clean on a boiler you have to watch everything closely
      anyway all accidents are preventable so the old partridges says but yet man in his nature is imperfect so it is a contradiction just by the nature of it. Engineers have to be held to account for failed designs and or products and or procedures that they implement
      Engineering is a science of redundancy and preventing failure but yet we have colossal failures I think all Engineers need to be an operator for 3 years in residency before they can begin their craft might help some

What’s That Strange Power Plant Smell?

The 73rd “Rest Of” Power Plant Post

Originally posted July 18, 2014

Given that a large Coal-fired Power Plant is like a small city complete with a water treatment system to supply drinking water to thirsty Power Plant Men, and it’s own complete sewage system to handle the volumes of human waste and toxic run-off, when I ask, “What is that strange smell?” You may expect the answer to be something like “Honeysuckle?” If you thought, rotten fish, diesel oil, ozone or sweaty arm pits, you would, of course, be wrong. Those are all the usual smells found in a Power Plant. Every so often, a smell would come by that would make you stop in your tracks and wonder…. “What’s that strange smell?”

Over the course of the 20 years I worked in the Coal-fired Power Plant in North Central Oklahoma, there were times when a new smell would just come out of no where. There were other times when they would sneak up on me gradually, so that I wouldn’t even notice them until they were gone…. Then I would wonder why it was that I didn’t notice them when they were there.

One such smell that stung me like a bee would happen when I was on overhaul and I was walking out to the precipitator all covered in a fly ash suit from head-to-toe wearing a full face respirator with duct tape around all of the seams.

 

This isn't me, this is just some other fortunate soul I found on Google Images

This isn’t me, this is just some other fortunate soul I found on Google Images

I was walking in the breezeway between the two boilers when I suddenly smelled a sharp sort of smell. It was a strange chemical I hadn’t ever noticed before. I looked around to see where it was coming from. There wasn’t anyone around, and I didn’t see anything chemical spill in the area that would account for it.

As I walked toward the precipitator, I looked up as I walked under the surge bin tower in time to see an operator coming down the stairs. He was smoking a cigarette. Besides that, everything else looked normal, except that the smell was almost overwhelming me at that point.

I went and climbed in the precipitator where I worked until break. When I came out, I blew the dust off of myself with a tiny instrument air hose that we kept on either side of the precipitator for just such an occasion. After the fly ash had been blown off of my suit, I leaned forward and pulled my respirator off of my face and breathed the fresh air.

Later that week, when I was heading back out to the precipitator and had just left the electric shop all dressed up in my suit, I had a whiff of that same smell. I couldn’t mistake it. It was a unique chemical smell. looking around, there wasn’t anyone or anything near me that would have been emitting such a toxic smell.

As I walked around the condenser to head toward the boiler, I saw that a couple of mechanics were carrying some planks of wood and laying them by the condenser in order to build a scaffold once they opened the condenser. One of the guys was smoking a cigarette. I wondered… Could it be a cigarette that smells so rancid? It didn’t seem likely, since I began detecting the smell when I was more than 40 yards away from the operator when he was descending from the Surge bin tower. I shouldn’t be able to smell a cigarette from that distance.

After a few more instances, I realized that it was cigarettes that I was smelling. I was amazed by how far away I could detect a cigarette when I was wearing my respirator. I figured that after it had filtered out all the particles bigger than 2 microns, the only particles and odors that were entering my respirator were easily detectable by my nose. And they didn’t smell anything like a cigarette.

I became so astute at detecting smokers, that one time I was walking through the breezeway with an unfortunate contract worker that had been commandeered to work with me, I was dressed in my fly ash suit and respirator. My helper wasn’t because he was going to be my hole watch while I was inside. I suddenly smelled that, now familiar, scent. I spun around once and then turned to the guy walking with me, who hardly knew who I was, and said, “Someone is smoking a cigarette!”

He looked around and no one was in sight. He said, “There isn’t anyone here.” I said, “Oh, there’s someone with a cigarette all right.” About that time a truck pulled around the end of the precipitator about 50 yards away with a couple of welders pulling a welding machine behind. Their windows were open, and hanging out of the driver side window was an arm, with a hand on the end (like a normal human being) holding a cigarette. As it drove by us, I pointed to the cigarette and said, “See. Cigarette.” He kept insisting I couldn’t have smelled that cigarette that far away… But with my respirator on, I could easily smell it.

One of the other strange Power Plant smell that I encountered during my tenure at the Power Plant was also while I was wearing my respirator and working in the precipitator. Only, I didn’t pay much attention to it until it was gone. Then I did everything I could to find the source of that smell, because to me, it was a sweet smell of success, even though it smelled more like a sweaty arm pit, or maybe even something worse.

I mentioned this smell in the post: “Moon Walk in a Power Plant Precipitator“. The precipitator is what takes the smoke out of the exhaust from the boiler, and collects it in hoppers and then blows it a half mile through a pipe to a silo on a hill by the coal pile, where it is trucked away to be made into concrete.

It was my job during an outage to repair the inside of the precipitator, and I was always looking for ways to improve the efficiency of the ash gathering abilities of this large piece of equipment.

The plant has a similar electrostatic precipitator, only ours is twice as long

The plant has a similar electrostatic precipitator, only ours is twice as long

I knew at certain times during an outage that the ash that had built up on the plates would all of the sudden decide to cake up and fall off in chunks leaving a perfectly clean plate. When that happened, then the odds of the precipitator running real well when we came back online was a lot better.

I also knew that after working long hours in the precipitator for a couple of weeks, I would feel all worn out like I had a flu. I would have to drag myself out of bed in the morning and I would even catch myself falling asleep on my feet inside the precipitator while I was inspecting it. I always figured it was just because we were working 10 or 12 hour days and I was getting older. Yeah…. 30 years old, and I was feeling every bit of it.

Then one day when I went to the tool room to get a couple of boxes of respirator filters Bud Schoonover told me that he couldn’t give me the regular hepa filter that I was used to using. I already knew that the regular filters weren’t good enough, so I asked him what else he had. He said, “Well…… I have some of these here…” I have mentioned that if Bud had been African American and a little bit skinnier and shorter, he would have been the spittin’ image of Aunt Esther from Sanford and Son’s. He would make this same expression:

Aunt Esther from Sanford and Son

Aunt Esther from Sanford and Son

Bud Schoonover

 

Bud handed me a box of filters labeled: Organic Vapor Filter:

 

Like This filter, only without the purple plastic guard. It had a cotton looking filter on the top

Like This filter, only without the purple plastic guard. It had a cotton looking filter on the top

It wasn’t exactly what I was looking for, but I didn’t have much choice. I could see that it had a carbon filter on it as well as the regular filter, so I thought it would be all right.

The first thing I noticed when I stepped into the precipitator wearing the Organic Vapor filter was that the air inside the precipitator didn’t smell any different than the air outside. I wasn’t used to that. I was used to smelling a “boiler” sort of smell. After a couple of weeks that smell would turn more rancid. Sort of a sour smell. When I noticed that I wasn’t smelling the sour smell I quickly broke the seal on my filter and sniffed the air to verify that the filter was really blocking the stench that built up in the precipitator the past few weeks. Sure enough.

Then I noticed that I was no longer feeling tired in the morning. I was able to work all day without feeling fatigued. I came to the conclusion that whatever that smell was that was being blocked by this respirator had been causing me to feel ill. Now that it was gone I was beginning to believe that 30 years old wasn’t that old after all.

I was already curious about the smell in the precipitator because I had noticed that after a day or so after it showed up, the ash would just flake off of the plates in the precipitator. If we could find out what it was, maybe we could inject something in the inlet of the precipitator when it was online and needed to be cleaned after a bad start-up or after it had been running a while to make it run more efficiently.

So, I went to our resident Doctor of Chemistry, George Pepple. I wrote a post about him, see “Power Plant Doctor Does a Jig in a Puddle of Acid“. I explained to him about the smell and about how this particular filter filtered it out when a Hepa filter didn’t. And the effect it had on the ash on the plates. He listened intensely and I could tell that I had made him excited. There are only so many chemicals a plant chemist deals with on a normal basis, so when Dr. Pepple had an opportunity to explore something new, he jumped at the opportunity.

When I took him to the precipitator, he could smell the odor even before we began climbing the stairs up to the open hatchways. He described it as a sewage type of odor. Which I hadn’t really thought of before, but come to think of it, that would explain why an organic vapor filter would work on it. I suggested that the sulfur in the ash might be giving it that.

I had analyzed the chemicals that made up the coal that we received at our plant from Wyoming and I had tried to figure out how it might combine with moisture to create a new chemical. George explained that when the coal burns under such a high temperature, a lot of the chemicals are sort of encapsulated in ways that are not easily predictable.

George suggested that we approach this as a Safety issue and contact the Safety Department in Oklahoma City and have them see if they can put an analyzer in the precipitator to detect the chemical. When I contacted them, I talked with a lady called Julia Bevers (thanks Fred for reminding me of her last name). She told me to call her when the odor was strong during the next outage and she would bring some chemical detectors to the plant and I could place them in there and let them run overnight to collect samples.

Julia had said that she had heard that I was known as “Mr. Safety” at the plant. I don’t know why. Maybe it was because I was in the habit of complaining. And a number of the things I would complain about were safety issues.

Anyway, during the next outage as soon as I smelled the smell emanating from the precipitator I gave her a call and the next morning I received a call from Toby O’Brien, the Plant Engineer Extraordinaire.  He called me and told me that Julia the Safety Lady was there in his office looking for me.

Power Plant Engineer and Good Friend - Toby O'Brien

Power Plant Engineer and Good Friend – Toby O’Brien

So, I went to Toby’s office and met “The Safety Lady.” I know I didn’t look at all like she expected. I was in a worn tee-shirt, not tucked in (on purpose) and worn out steal-toed boots. When I took her out to the Precipitator, I decided to take her across the Turbine Generator room and out the Third floor to the boiler where we walked through the boiler and over to the precipitator up and down ladders.

When we walked across the Turbine Floor, I didn’t have my usual pair of ear plugs hanging around my neck (they were in my pocket — on purpose). As it was rather loud, Julia turned and said, “Shouldn’t we be wearing earplugs?” I replied, “Huh?” As if I couldn’t hear her. — I just love playing Power Plant Jokes on people that don’t even know what you’re up to… I’m sure when we were done, she went straight back to Toby and told him how shocked she was to find out how unsafe I was. — Me trying to keep a straight or even confused look on my face the entire time.

Earplugs on a cord that can be draped over your shoulders when not in use.

Earplugs on a cord that can be draped over your shoulders when not in use.

To shorten a longer story, Julia gave me some indicators that would detect two different types of chemicals that she thought may be the culprit. I left the detectors in the precipitator overnight and then sent them back to Oklahoma City for analysis. They both came back negative leaving us with a mystery chemical.

Anyway, I never did find out what was causing that strange smell….

There was another strange smell that used to pop up in the Electric Shop when I had first become an electrician, but that just turned out to be one of our fellow electricians that liked to walk up to a group of electricians standing around talking, and then let loose a “silent but deadly” and then walk away and stand from a distance to see our reaction.

I won’t mention who that was, unless someone would like to leave a comment about that below….. Anyway. we all knew who it was when that happened as the electricians would yell out his name as the crowd quickly dispersed.

I decided to take a different approach. I would stand there thinking, trying to analyze the odor to see if I could tell what exactly this person had for supper the night before. I could tell one day when I said “Beef Stroganoff” and his face turned red that I had guessed pretty close to the mark….. That was the last time this noble Power Plant Man did that to a crowd of electricians….. at least when I was standing there… I can’t attest to any other time…. as I wasn’t there.

But I suppose that is proof that even early in my career I was interested in finding the source of that “strange smell”.

Power Plant Law of the Hog

The 72nd “Rest Of” Power Plant Post

Originally posted 6/27/2014

Power Plant Men learned about the “Law of the Hog” the first day they were introduced to the new “Quality Process”. I recently wrote a post about how the Power Plant Men at the Coal-fired Power Plant in North Central Oklahoma were trained to use various tools to help them formulate ideas quality improvement ideas at the plant in June, 1993. See the post “A Chance for Power Plant Men to Show Their Quality“. Even though we were hearing about the “Law of the Hog” for the first time, I recognized it right away. I had seen it in action the previous November 3, 1992.

What better way to convince a room full of skeptical Power Plant Men that the Quality Process is about improving the conditions at the plant than by first telling them what they already know in such a way that from then on they believe you really do know what you’re talking about. — I know. That was a confusing sentence, so let me explain. The instructor told us the story about “The Law of the Hog”.

This evidently was a story that had been going around since the late 70’s. It had to do with a saw mill in Oregon. This is the story the instructor told us…

A group of quality consultants, or… I think they called themselves Leadership consultants back then were visiting the saw mill because they evidently needed some help. While the consultants were learning about how the plant operated, they talked with the workers one-on-one and asked them how things were “really” done at the saw mill. That’s when the workers told the consultant about “The Hog”.

The Hog is a grinder that takes scrap wood and grinds it up into sawdust. The consultants had asked them how they worked with supervisors when they were “lacking” in leadership skills. (I would say “evidently” again here, but I’ve already used that word three times. And the last time was just now while explaining that I would like to use that word again, but… — I’ll have to think of another word…. let’s see… oh. I know…. Apparently…). Anyway, apparently, that was when they told the consultants about The Hog that lived in the shack off to one side of the main mill.

So, what happens is that when their supervisor uses a heavy hand to try to whip the workers into shape, the Hog is used for more than just chewing up scraps. When the workers were treated with disrespect, then “The Law of the Hog” went into effect. What happened then was that the workers would throw perfectly good pieces of wood into the Hog where it would be turned to dust (saw dust that is). Since the supervisors were measured on their productivity which took a beating when good wood would be destroyed (Yeah. I couldn’t help using the words Wood and Would together… And then using “Words”, “Wood” and “Would” all together while explaining my obsession.  Sort of like “How much wood would a woodchuck chuck”). So, the workers would pay the supervisor back each time he displayed inferior leadership skills.

A byproduct of bad leadership

A byproduct of bad leadership – looks like the right side has better leadership than the left side.

Oh yeah. The Power Plant Men knew all about that. The guys at Muskogee, however, didn’t use such indirect methods. They had one Assistant Plant Manager (I won’t tell you his name but I think his initials were Morehouse. well. Something House anyway), that treated his men with a little more than disrespect. He was surprised one night when the front door to his house was blown off the hinges. He was quickly reassigned to Oklahoma City. But then I have always said that something is in the water in Muskogee. See the post “Something is in the Water at the Muskogee Power Plant“.

When the Quality instructor was telling us the story about the “Law of the Hog” a few examples immediately entered my head. Well, one was the Six Hour Rule. I mentioned this in an earlier post where there was a complicated rule about how an employee could collect “black time” and double time when they were called out at night. As management tried to manipulate the rule to the detriment of the employee, the opposite effect actually happened. After trying to skimp on paying the double time the employee was accustomed to, that was the time when I made the most money from that rule. See the post “Power Plant Black Time and Six Hour Rules“.

This leads us to a dark and stormy day at the Power Plant…. November 3, 1992. The story actually begins the day before. Unit 2 had been offline for a “more than” minor overhaul (I believe it was a six week overhaul instead of the usual 4 weeks). I was the acting foreman for the crew that was working on the precipitator. Terry Blevins normally was in charge of the Unit 2 Precipitator, but for this overhaul, Scott Hubbard and I were assigned to make all the necessary precipitator repairs. The main reason was that new rapper controls were being installed, and Scott had a lot of experience doing this since he had installed them on Unit 1 already.

Scott Hubbard

Scott Hubbard

At that time, Scott and I were like twin brothers. Whatever he was doing… I had to be there to help. Scott would work on the roof of the precipitator generally, while I worked inside. We had been given some operators to help us along with a few contract workers to do the “grunt” work. That is, when you would ask them to do something, they would usually reply with a low moaning grunty sort of sound (I just made up that word…. grunty. It seemed to fit.  Feel free to use it).

Needless to say (but I’ll say it anyway just in case any “Non-Precipitator Gurus” are reading this)…. in order to install the new digital rapper controls, a lot of wire had to be pulled and laid down on terminal blocks from some rapper cabinets to other cabinets across the precipitator. When I say a lot, I mean somewhere over 10 miles of wire. 15 feet at at time. — I was sure glad Scott was doing that while I was strolling away inside the precipitator quietly looking for plates out of alignment and broken wires dressed in my space suit. For a better understanding of what a precipitator does, see the post “Moon Walk in A Power Plant Precipitator“.

I was not inside the precipitator on November 3, 1992, however, I had already finished up inside the precipitator by that time and I was working on the roof in cabinet 2G1 (on the southeast corner) on that day. We had the radio on and I was sitting on my bucket listening to Rush Limbaugh throwing a fit (as he has been known to do from time-to-time). None of our help was doing any work that day. The “Law of the Hog” had come into play and a day of rest had been declared by the helpers.

I was working away laying down the wires on the terminal blocks inside the rapper cabinet while the rest of the crew (minus Scott Hubbard who was on the far side of the precipitator roof working in another cabinet) was sitting around dangling their feet from the walkway near my cabinet. Merl Wright and Jim Kanelakos (two operators) were there along with three contract help. During that day I spent a lot of time running back and forth between the office area and the precipitator roof.

Here is what happened:

On November 2, 1992, just before every one left for the day, the word came down that in the morning everyone was supposed to report to work at the usual 7:00 time. We were scheduled to work until 7:00 in the evening. A full 12 hour day, except for the 30 minutes for lunch (and three breaks). The reason we had to be told to show up at seven o’clock in the morning was because November 3rd was election day.

It was the normal practice to let the Power Plant Men vote before they came to work in the morning. We were being told that we were not supposed to vote in the morning and that we could leave early in the evening to go vote instead of voting in the morning. We were told in no uncertain terms that if we went to vote in the morning, then the amount of time we were late getting to work would be the amount of time we would have to leave at the end of a normal working day.

Let me try to explain what this meant, because on the surface, it looks fairly reasonable. Since the polls closed at seven in the evening when we would be leaving work, we could leave as early as we wanted in the evening to go vote in order to arrive in time before the polls closed. There were two things fundamentally wrong with this solution from a Power Plant Man point of view, though from a Plant Manager point of view, it looked quite reasonable.

The first problem was that this was the election between George Herbert Walker Bush and Bill Clinton (Now you know why Rush Limbaugh was throwing a fit). A very large turnout was expected, and a majority of the workers wanted to make sure and go to the polls to vote that day. With that said, it would be hard to determine what would be a good time to leave the plant to go vote in order to stand in line and cast a vote before the polls closed. Up to that time, polls had not been kept open later than their designated closing time, except to let people who were already waiting in line by the time the closing bell rang.

The second problem and the main problem was this….. Suppose a person did go vote in the morning…. It was a typical practice for the company to cover that person’s time and pay what was called “Black Time” while they went to vote in the morning. In this case, the plant manager was telling us that we basically couldn’t go vote in the morning without being “punished”. If the person waited and voted in the evening, they would lose their overtime which directly affects the bottom line on the home front.

Here is how the punishment would be administered…. If a person went to vote in the morning and was an hour late, and came in, say at eight o’clock instead of seven. Then they would have to leave when they had completed a regular eight hour day. That is, they would not receive any overtime that day.

Well. this didn’t effect me, because I had already early voted a couple of weeks earlier. I think Scott did too, when we realized we were going to be on overhaul working 12 hour days. Scott Hubbard and I carpooled together, so we were always careful to coordinate our efforts.

So, guess what happened…. Yeah. You guessed it…. especially if you knew Jim Kanelakos. He knew an “injustice” when he saw it, and so, he wasn’t going to let this one slide. He made sure to go vote the first thing in the morning, just like he had ever since he was old enough to vote. He arrived at the plant around 9 o’clock.

When he arrived on the Precipitator roof he told me that he had voted that morning and that the line at the polls where he voted was down the block 15 minutes before they opened. He said he didn’t care what anyone said, he was going to work until 7:00 that evening. He said, “Just let anyone try to send me home early,” with a big grin on his face and his pipe hanging from the corner of his mouth…. Oh. Let me remind you what Jim looked like:

This picture reminds me of Jim Kanelakos

This picture reminds me of Jim Kanelakos

This is a picture I found a few years ago on Google Images. It looked like Jim, so I copied it. Since then I have received a picture of the crew Jim was working on, so you can see an actual photo:

Jim Kanelakos in in the middle in the back (third from the left) with the red plaid shirt standing behind Vonzell Lynn

Well… When Tom Gibson, the Electric Supervisor came around asking if anyone had arrived late that morning, as acting foreman, what could I say? I told him that Jim Kanelakos had come in two hours late. Tom told me to send Jim home at 4:30. He would get his black time for voting early, but he would not receive any overtime for the day. I told Tom I would tell Jim. I also told him that Jim had already said that he was going to stay until 7:00 and expected to receive the normal pay that he would have received if he had worked the entire day.

This sent Tom into a rage. He wanted Jim taken off our crew and sent back to Operations right then and there. He said that he disobeyed orders and if it was up to him, he would fire him. I told Tom that we had a ton of work to do and that we needed everyone we could have until the overhaul was over. If we sent Jim back to Operations for the remainder of the overhaul, we might not be able to finish our work. We were working on a very tight schedule as it was.

I told Jim that Tom had told me to tell him to go home at 4:30 in the afternoon. Jim just laughed. He said he was going to go home at his regular time…. 7:00 pm. I said, “Ok. I am just telling you what Tom said. I’m going to have to tell him your reply.” Jim, who was my friend, said, “I know. Do what you have to do.”

I went back to the electric shop and when I walked in the shop Denise Anson, the receptionist paged me on the Gray Phone. She said I had a call. I told her to send it to the electric shop office. I was surprised when I answered the phone and Charles Campbell was on the other end of the line. News travels fast…. He was an attorney in Stillwater. He had heard that there was something going on at the plant that might have something to do with vote tampering.

I told him in detail what I knew about Jim Kanelakos and how he had went to vote in the morning after being told that he had to wait until the evening to vote, or he would be docked pay by missing out on scheduled overtime. I knew that Charles Campbell, unlike some attorneys, was an upstanding citizen in the community and was in no way an ambulance chaser, but when he heard this, I could immediately hear the eagerness in his voice.

I had the impression by his remarks that if this panned out the right (I mean “the wrong”) way, he might be able to retire early. We ended the conversation by him saying, “Let me know if you hear about anyone that doesn’t get to vote that wanted to because they left work too late.” He was in total disbelief that the plant had made that policy.

Well, I found Tom Gibson in his office and I told him what Jim had replied to me. Tom became even more furious. (I only saw him this mad or his ears this red one other time… but that is another story – See the post “Power Plant Customer Service Team Gone Wild“). He repeated that he was going to try to have Jim fired for being insubordinate. This seemed to me to be unlike Tom who was always a very reasonable person. I don’t think it was anything personal against Jim, I think there was just something about someone who blatantly (in his mind) had ignored a policy that had been clearly given to him the evening before.

I ended up in the Plant Manager, Ron Kilman’s office. Ron, who took ultimate responsibility for the decision to tell the employees to not vote in the morning listened to Tom tell him what he thought about the whole thing. I had been in Ron’s office not too long before this incident to tell him that someone had been hacking through our phone system and it surprised me that Ron wanted to find a way to resolve the issue without raising a ruckus or harming anyone, even the perpetrator. See the post “Turning the Tables on a Power Plant Telephone Interloper“. When Ron was questioning me about the issue about what to do with Jim, I could tell that Ron really wanted to resolve this issue with as little conflict as possible.

I told Ron that I had talked to my attorney in Stillwater about what was happening and that he was very anxious to find out if anyone either lost any money because they voted early, or they were not able to vote at the end of the day. Ron said, “Well. We made this decision yesterday afternoon without really thinking it through. When the idea was suggested, it sounded like a good plan at the time. Then today I went and checked to see what we have done in the past, and we have always let people go vote in the morning.” Ron’s final decision was to let Jim continue working until seven o’clock and receive the proper black time for voting in the morning. I let Jim know.

Everything would have been all right except for one thing….. The Law of the Hog. You see, I had spent considerable time going back and forth throughout the day between the precipitator roof and the office area discussing this topic with both parties involved. The entire precipitator crew with the exception of Scott Hubbard, did absolutely no work the entire day. They kept waiting to see what was going to happen. We were now one day behind schedule.

    I knew Jim well, and after his service to our country in Vietnam, no one or entity was going to stop him from voting, at whatever time he chose to vote, and all the years i worked with and knew Jim , he never missed an election and pointed out to me once that when I did not vote, how he had fought and served for our right to vote and that I should never miss again, one time I was real sick and a single guy Jim shows up prepares me some hot chicken soup.  Jim was all about justice and expected intelligence and light in all things and was a truth seeker.  He had his faults.  Who doesn’t?  But he was a good friend to me.

A Chance for Power Plant Men to Show Their Quality

The 71st “Rest Of” Power Plant Post

Originally posted June 21, 2014.

I don’t know if anyone of us knew what to expect Wednesday morning January 13 , 1993 when we were told to go to a meeting in the break room that was going to take all day.  We were supposed to be in some kind of training.  Everyone at the plant was going to have to go through whatever training we were having.  Training like this always seemed funny to me for some reason.  I think it was because the hodgepodge of welders, mechanics, machinists, electricians and Instrument and Controls guys seemed so out of place in their coal-stained worn out old jeans and tee shirts.

I remember walking into the break room and sitting down across the table from Paul Mullon.  He was a new chemist at the time.  He had just started work that day.  We became friends right away.  Scott Hubbard, Paul and I were carpooling buddies.  He always looked a lot younger than he really was:

Paul Mullon when he was 90 years old

My favorite picture of Paul Mullon when he was 90 years old

See how much younger he looks?  — Oh.  That’s what I would always say about Gene Day because he was always as old as dirt.  Even when he was young.  Paul is only four years older than I am, but he still looks like he’s a lot younger than 70.

Even his great great grand daughter is saluting him in this photo.  Actually.  I love Paul Mullon as if he was my own brother.  He still looks younger than my younger brother who is four years younger than I am.  People used to think that Paul was his own daughter’s boyfriend.

When our training began, the plant manager at the coal-fired power plant in North Central Oklahoma, Ron Kilman came in and told us that we were going to learn about the “Quality Process”.  He explained that the Quality Process was a “Process”, not a “Program” like the “We’ve Got The Power Program” we had a few years earlier.  This meant that it wasn’t a one time thing that would be over any time soon.  The Quality Process was something that we will be able to use the rest of our lives.

At this point they handed out a blue binder to each of us.  The title on the front said, “QuickStart – Foundations of Team Development”.  A person from a company called “The Praxis Group”, Rick Olson from Utah (when I originally posted this last year, I couldn’t remember his name.  Then I found my Quality book and it had Rick’s name in it).  I had looked Rick Olson up to see if he was a member of CompuServe and there was Rick Olson from Ogden, Utah.  When I asked him if he was from Ogden, he told me he was from Provo, Utah.

One of the first things Rick asked us to do was to break up into teams of four or five and we were asked to come up with 3 facts about ourselves.  Two of which were true and one that was false.  Then our team mates were asked to vote on which fact they thought was the false one.

The only one I remember from that game was that Ben Brandt had dinner with the Bill Clinton on one occasion when he was Governor of Arkansas.  — At least, I think that was what it was…  Maybe that was the fact that was false.

The purpose of this game was to get to know each other….  Well….  We had all been working with each other for the past 15 years, so we all knew each other pretty good by that time.  Except for someone new like Paul.

I think my false fact was that I had hitchhiked from Columbia, Missouri to New Orleans when I was in college.  — That was an easy one.  Everyone knew that I had hitchhiked to Holly Springs National Forest in Mississippi, not New Orleans.

Anyway, after we knew each other better, we learned about the different roles that members of our teams would have.  Our “Quality” teams were going to be our own crews.  Each team was going to have a Leader, a Facilitator, a Recorder, and if needed (though we never really needed one), a Logistics person.  The Logistics person was just someone that found a place where the team could meet.  We always just met in the Electric Shop office.  I wanted to be “Facilitator”.

We learned about the importance of creating Ground Rules for our Quality Meetings.  One of the Ground rules we had was to be courteous to each other.  Another was to “Be willing to change” (I didn’t think this really belonged as a “Ground Rule”.  I thought of it more as a “Nice to have” given the present company).

Another Ground Rule was to “Discuss – Don’t Lecture”.  One that I thought was pretty important was about “Confidentiality”.  We had a ground rule that essentially said, “What happens in a team meeting… Stays in the team meeting.”

I recently found a list of the Quality teams that were formed at our plant.  Here is a list of the more interesting names and which team it was:  Barrier Reliefs (that was our team — Andy Tubbs team).  Rolaids (Ted Holdges team).  Elmore and the Problem Solvers (Stanley Elmore’s team… of course).  Spit and Whittle (Gerald Ferguson’s Team).  Foster’s Mission (Charles Foster’s team).  Sooner Elite (Engineer’s team).  Boiler Pukes (Cleve’s Smith’s Welding crew I believe).  Quality Trek (Alan Kramer’s Team).  Designing Women (Linda Dallas’s Team).  There were many more.

I think all the Power Plant Quality Teams had the same “Mission Statement”.  It was “To Meet or Exceed our Customer’s Expectations”.  I remember that the person that was teaching all this stuff to us was really good at motivating us to be successful.

As we stepped through the “QuickStart” training manual, the Power Plant He-men were beginning to see the benefit of the tools we were learning.  There were those that would have nothing to do with anything called “Quality”, just because… well…. it was a matter of principle to be against things that was not their own idea.

Later they gave us a the main Quality binder that we used for our team meetings:

Our Quality Manual

Our Quality Manual

When we began learning about the different quality tools that we could use to solve problems, I recognized them right away.  I hadn’t learned any “Quality Process” like Six Sigma at that time, but I was about to graduate from Loyola University in New Orleans in a couple of months with a Masters of Religious Education (MRE) where I had focused my courses on Adult Education.  Half of my classes were about Religious topics, and the other half was about how to teach adults.  The same methods  were used that we learned about in this training.

It just happened that I had spent the previous three years learning the same various quality tools that the Power Plant Men were being taught.  We were learning how to identify barriers to helping our customers and breaking them down one step at at time.  We also learned how to prioritize our efforts to break down the barriers by looking at where we had control and who we were trying to serve… such as ourselves or others.  I remember we tried to stay away from things that were “Self Serving.”

We learned how to do something called a “Barrier Walk”.  This was where we would walk around the plant almost as if we were looking at it for the first time to find barriers we hadn’t noticed before.  We also learned how to brainstorm ideas by just saying whatever came to our minds no matter how silly they may sound without anyone putting anyone down for a dumb idea.  Rick called each barrier that your customer encountered a “SPLAT”.  Our goal was to reduce “SPLAT”s.  I think at one point we even discussed having stickers that said “SPLAT” on them that we could put on barriers when we located them.

When we implemented a quality idea, we were taught to do a “Things Gone Right, Things Gone Wrong” exercise so that we could improve future projects.  This had two columns.  On one side you listed all the good things (which was generally fairly long), and on the other, all the things that went wrong (which was a much shorter list).  This was done so that we could consider how to avoid the things that didn’t work well.

We learned how to make proposals and turn them into a team called “The Action Team”.  I was on this team as the Facilitator for the first 6 months.  Sue Schritter started out as our Action Team Leader.  The other Action team members in the beginning were:  Richard Allen, John Brien, Jim Cave, Robert Grover, Phil Harden, Alan Hetherington, Louise Kalicki, Bruce Klein, Johnnie Keys, Kerry Lewallen, Ron Luckey and George Pepple.

The Power Plant Men learned that there were five S’s that would cause a proposal to fail.

One of those was “Secrecy”.  If you are going to propose something that affects others, then you have to include them in the decision making up front or else even if you think it’s a great idea, others may have legitimate reasons for not implementing it, and you would have wasted your time.

The second was “Simplicity”.  It follows along with Secrecy in that if you just threw the idea together without considering all the others that will be affected by the change, then the proposal would be sent back to you for further study.

The third was “Subjectivity”.  This happens when something just sounds like a good idea.  All the facts aren’t considered.  The solutions you may be proposing may not be the best, or may not even really deal with the root of a problem.  You might even be trying to solve a problem that doesn’t really exist, or is such a small problem that it isn’t worth the effort.

The fourth was “Superficiality”.  This happens when the outcomes from the proposal are not carefully considered.  Things like, what are the long term effects.  Or, What is the best and worst case of this proposal…  Those kind of things are not considered.

The last one is “Self-Serving”.  If you are doing this just because it benefits only your own team and no one else, then you aren’t really doing much to help your customers.  Most likely it may even be causing others an inconvenience for your own benefit.

I know this is becoming boring as I list the different things we learned that week in 1993.  Sorry about that.  I will cut it short by not talking about the “Empowerment Tool” that we learned about, or even the importance of Control Charts and go right to the best tool of them all.  One that Power Plant Men all over can relate to.  It is called the “Fishbone Diagram”.

Fishbone Diagram

Fishbone Diagram

There are few things that Power Plant Men like better than Fishing, so when we began to learn about the Fishbone diagram I could see that even some of the most stubborn skeptics couldn’t bring themselves to say something bad about the Fishbone diagram.  Some were even so enthusiastic that they were over-inflating the importance (and size) of their Fishbone diagrams!  — This along with the Cause and Effect chart were very useful tools in finding the root cause of a problem (or “barrier” as we referred to them).

All in all, this was terrific training.  A lot of good things were done as a result to make things more efficient at the plant because of it.  For the next year, the culture at the plant was being molded into a quality oriented team.  This worked well at our particular plant because the Power Plant Men employed there already took great pride in their work.  So, the majority of the crews fell in behind the effort.  I know of only one team at the coal yard where the entire team decided to have nothing to do with it.

When training was done, I told Rick that I thought that his company would really benefit by having a presence on the Internet.  As I mentioned in last week’s post “Turning the Tables on a Power Plant Interloper”  During this time the World Wide Web did not have browsers and modems did not have the bandwidth at this point, so CompuServe was the only service available for accessing the Internet for the regular population.

I asked Rick if he had heard about CompuServe.  He said he had not heard of it.  I told him that I thought the Internet was going to be the place where training would be available for everyone eventually and he would really benefit by starting a “Quality” Forum on CompuServe, because there wasn’t anything like that on the Internet at the time.  I remember the puzzled look he gave me as he was leaving.  I realized he didn’t have a clue what I was talking about.  Few people knew about the Internet in those days….

I have a number of stories about how the Quality Process thrived at the Power Plant over the next year that I will share.  I promise those stories will not be as boring as this one.

Turning the Tables on a Power Plant Telephone Interloper

The 70th “Rest Of” Power Plant Post

Originally posted June 13, 2014:

When discussing Telephones at the Coal-Fired Power Plant in North Central Oklahoma, I have to remember that some of my readers have a completely different perspective of telephones than me. My children grew up probably never seeing a real rotary dial phone except in movies or old TV shows. It might be a little hard for them to imagine a telephone being a possible murder weapon. Telephones have come a long way since I grew up in the 1960’s and 70’s.

A Rotary Dial Telephone

A Rotary Dial Telephone

When you turned the dial on a Rotary phone you put your finger in the hole on the number you want to dial and then you swing it around until your finger bumps up against the metal bracket. When you pull your finger out of the hole, the phone sends a rapid succession of pulses to the telephone company telling them what number you just dialed. It was very… well…. tedious and manual…. and not even electronic. It was electric signals and switches. “Mechanical” is the word I think I’m trying to say.

Even the way you received a dial tone was by sending something called a “Ring-to-ground” signal to the telephone company. That would happen when you would lift the receiver off the hook. There are only two wires used to communicate in an old phone and only one of those had voltage on it. when you ground that wire (called the “Ring”) momentarily, the phone company would then send a dial tone to your phone.

You could actually do this on a dead phone line at times when the phone company had shut off your service. On an old pay phone, when the proper coin was inserted in the phone, the coin itself was used to ground the ring wire, thus telling the telephone company to send the dial tone, allowing you to use the phone. In 1983 there was a movie called “Wargames”.

Wargames Starring Matthew Broderick and Ally Sheedy

Wargames Starring Matthew Broderick and Ally Sheedy

I had learned about how these telephones worked from Bill Rivers just before going to watch this movie. During the movie Matthew Broderick’s character needed to make a phone call at a pay phone but didn’t have a coin. By taking the mouthpiece off of the transmitter, and using a metal pop top he found on the ground, he was able to ground the “ring” wire to the pay phone, and he received a dial tone. There was a good ol’ boy sitting behind me in the movie theater that said, “You can’t do that!” — Being the newly educated smart (-alec) guy I was, I turned around and said, “Yeah. You really can.”

Anyway. This isn’t a story so much about how old phones work. I just wanted to bring the younger readers back-to-date on phones since now they don’t really call them telephones anymore. It is more like, “Smart Phone” and “Cell Phone”, “Mobile Phone” or just “Phone”. The phone in the house isn’t even referred to as a telephone. We now call them “Home Phone” to distinguish them from the actual phones that we use.

Anyway, when I joined the electric shop in 1983, I learned about the phone system. We didn’t use the older Rotary Dial phones at the plant. We were one step up. We had “Touch Tone” Phones.

A Power Plant Touch Tone Phone

As I have mentioned in previous posts, we had our own telephone computer at the Power Plant. It was called a ROLM phone system. See the post “A Slap In the Face at a Gas-fired Power Plant“.

A ROLM Phone Computer

A ROLM Phone Computer – I like showing this picture of the Phone computer

To give you an idea of the technology used by this phone system, you connected to it using a “teletype” terminal that you connected to a telephone by clipping the receiver in a cradle. Then you dialed the phone computer. When you connected, it was at 300 Baud. Think of 300 bytes per second, only using audio…. like a fax machine. — It was like connecting using a modem. 300 baud meant that when it typed out the results on the paper that scrolled out the top, you could watch it as it slowly printed out each line. The maximum speed of the terminal was 300 baud.

 

This is the TI Silent 700 Terminal. We used this exact model of Teletype terminal at the Power Plant

In this picture you can see the cradle in the back where the phone receiver would fit in those two rubber cups.

After many years of going to the lab to connect to the telephone computer to make changes and to monitor the telephone traffic, in 1992 I decided to bring my 8088 computer to work and set it on the desk in the electric shop. We didn’t have our own computer yet. At that time the only people that had computers were office workers and the Shift Supervisor. We had started a computer club and having a computer in the shop was a big help. I had just replaced this computer at home with a 486.

This is a Leading Edge computer. My father had this one. An earlier version than the 8088 that I was using.

I had a modem on my computer, so I tried connecting to the telephone computer, and it worked! So, sometimes during lunch when Charles Foster and I were sitting there talking about movies we had seen while eating vegetables from his garden, I would connect to the ROLM computer and just watch the call log. I could see whenever someone was dialing in and out of the plant.

We had a special call in number into the plant that allowed you to make “trunk” calls. This is another term you don’t hear much anymore. You see….. for the younger readers (again)…. long distant calls used to cost a lot of money. You would be charged by how many minutes you were on the call. During the day, it could be as high as $3.00 a minute to call across the country. Amazing huh? Because today, most of you with cell phones and even your land lines (which are rarely real land lines anymore) long distant phone calls are now free with your phone plan.

Yeah, if you wanted to call someone in the next town over, you would have to pay a fee for every minute you were on the call…. That was when AT&T had a monopoly on the phone lines in the United States. Sure, you only payed $7.00 each month for your phone, but you could only call people in your immediate area or you would be charged extra.

A Trunk line gave you access to a much wider area. The Electric company had a trunk line that gave them access to most of Oklahoma. You could dial into a local number that would connect you to the company phone system. Then after entering the correct password number, you could dial access numbers that would take you to another office location in the electric company. Once on that phone system, you could dial to get an outside line, and then dial a local number in that area.

Our plant had three access numbers that allowed you to dial out locally to Stillwater, Ponca City and Pawnee. This was useful when a foreman needed to call people out to work. They could dial into the plant, then back out to one of these other towns and then dial the local phone number of the crew member they were trying to reach without incurring a personal charge on their phone line.

So, here I was in 1992 during lunch watching the phone traffic in and out of the plant (not exactly NSA style, but sort of), when I saw something unexpected. A long string of numbers showed up. Someone had dialed in on the Stillwater trunk, then dialed out to the Corporate Headquarters trunk, then out to Oklahoma City and from there they placed a long distance call to a phone number in the same area code. The prefix on the phone number was familiar to me. It was a Ponca City phone number. I had lived in Ponca City for three years when I had just been married, from 1986 to 1989. I knew a Ponca City phone number when I saw one.

I thought this was odd, because it wouldn’t be normal for someone to dial from Stillwater through our plant to Oklahoma City only to call a Ponca City phone number when they could have dialed the local Ponca City access code. Then they wouldn’t have had to make a long distance call which bypassed our trunk call system causing the electric company to be billed for the long distance telephone call.

At the time I was a CompuServe user. This was when the World Wide Web was in it’s infancy. I was still using a DOS computer. When I connected to the Internet, it was either by using my dad’s Internet account from Oklahoma State University where I would use Telnet to access a bunch of mainframe computers all over the country, or I would use the DOS-based version of CompuServe. CompuServe was the king of Internet access before America Online came around and seemingly overnight made CompuServe obsolete.

In 1992, CompuServe had a service where you could look up phone numbers and find out whose number it was. Imagine that! Yeah. That was one of the neatest features on CompuServe! That and getting stock quotes. — Like I said…. There was no “www.whitepages.com” online. The only catch to using the reverse phone number feature, was that it was like making a long distance call. It cost money. You were charged by the minute for using the CompuServe reverse telephone number service, with the least amount being a dollar.

So, I bit the bullet and accessed the Phone Number lookup section of CompuServe. I quickly typed in the number. When the name and address of the user popped up, I quickly hit “Print Screen”, and then exited the service. My fee came to $1.00, but at least I knew what number had been dialed in Ponca City.

Charles, Scott Hubbard and I were a little excited by the time Terry Blevins walked into the electric shop office after lunch was over, I told him what I had seen.

When I told Terry the name of the person that had received the long distance call, he recognized the name right away. When I gave him the address, he was sure he knew who it was. The phone number belonged to the Music Director at the Ponca City High School. His son was attending college in Stillwater, Oklahoma.

Well, that sort of cinched it. We had a pretty good idea who had made the call. It was a college student calling home, who had been given the phone number most likely by a fellow student who knew the code to call home in Oklahoma City. So, the only local access code this guy knew was how to dial through our plant to Oklahoma City and back out where he was free (but it was not free for us) to make a long distance call home.

Armed with this knowledge, I headed up to the front office. I went straight to the Plant Manager, Ron Kilman’s office. I told Ron what I had found. I explained in detail how the person had dialed from Stillwater into our plant and then to Oklahoma City and out and then placed a long distance call to Ponca City leaving us with the phone bill. Since it was the middle of the day, the cost of a long distance call was not cheap.

I told Ron that I had used CompuServe to lookup the phone number and that Terry had said that it belonged to the Music Director at the Ponca City High School and that he had a son in college in Stillwater. I was all ready to pounce on this guy. This was a fraudulent use of the telephone service and there were some pretty strict laws then about stealing long distance from someone else.

Ron, being the more level-headed of the two of us thought about it for a minute and said, “What would be the best way to stop this from happening?” — Oh. Well.  I was so intent on catching the culprit, I hadn’t thought about that angle…. “Well….” I said, “We could change the pass code used to log into our phone system. We would just have to tell our supervisors what the new number is.”

Ron asked me what it would take to do that. I told him I could do it in two minutes. We quickly settled on a new 4 digit pass code and I left his office and returned to the electric shop and made the change essentially turning the tables on the Telephone Interloper. I suppose the college student in Stillwater was lucky that our plant manager at the time was the type to forgive and forget.

Three years later the entire electric company phone system was replaced by a new AT&T computer which was managed by AT&T. As you can tell… Technology just keeps moving forward making seemingly really neat new inventions quickly obsolete.

Early Morning Power Plant Wake Up Call

The 69th “Rest Of” Power Plant Post

Originally posted May 30, 2014:

Unlike the story I told a few weeks ago about Jim Padgett, this is not a story about being called to work in the middle of the night by a true Power Plant Man (See post: “Making A Friends from Foes – A Tale of Power Plant Woes“) or even like the story that explained the “Power Plant Black Time and the Six Hour Rule“. No. This is a quick story about a sobering slap in the face I encountered when walking into the electric shop one morning at the Coal-fired Power Plant in North Central Oklahoma.

I think this must have been when I was on someone’s short list for a “Power Plant Joke”, or maybe I just hadn’t been paying attention a month earlier when Bill Bennett may have informed me that this morning was coming. Either way, I was totally taken off guard when I entered the shop that morning with Scott Hubbard, my Carpooling buddy.

The first indication that something was up was that there were three contract hands standing there dressed in their worn clothing indicating that they had been hired to do some kind of “manual” activity. Yep. Worn jeans with holes. Shirts slightly ripped. One guy missing the sleeves on his shirt. I think one of them had accidentally taken a shower before he showed up.  He may have mixed up his Mondays and Saturdays and woke up grumpy on Saturday and took a shower on Monday.

None of the contract hands had thought about shaving for the past week or so. So, they definitely looked out of place in the shop usually occupied by professional Power Plant Electricians, who liked to keep themselves clean and generally followed good hygiene practices.

My first thought was, “Hmm…. Looks like there is some dirty job someone has to do in the shop today. I wonder what it is.” I walked into the electric shop office to wait until 8:00 to come around. Bill Bennett was leaning against one of the desks talking to Charles Foster. I asked Bill, “What’s up with the Contractors?”

Bill replied, “They are here to help you.” “What am I going to be doing?” I asked curiously. “You know. Pulling wire from the Vital Service Panel to the Telephone Room in the main office.” “Oh. That.” I replied trying to remember if I could recall ever being told that I was supposed to be inheriting this particular job.

The last time I had felt like this was when I was in High School and our American History teacher, Mr. Wright told us that the semester class projects were due tomorrow and he continued to explain that we would be presenting the projects in alphabetical order. “Which means that Kevin Breazile. You will be going first.”

Side Story Time:

Class Project? Oh No! I had forgotten all about it! I was supposed to write a paper about the Roadway system in the United States, including how we were preparing to go to the Metric System.” (Like that ever happened… This was in 1976).

So, after school I went straight home and told my mom that I needed to go to the Public Library to prepare for a class project that needed to be done tomorrow. At the library I quickly grabbed a bunch of facts out of encyclopedias. I made up a few statistics about how many miles of roads there were in the United States.

Then once I was back at home, I thought about the roads in the U.S. Well, there were dirt roads, gravel roads, asphalt roads, and roads made of concrete. So. I filled a jar with dirt. One with some rocks I found out in the street. I found a piece of asphalt that had worked itself loose at the intersection by my house. I also found a chunk of concrete under our deck in the backyard where we had busted up our patio once to pour a new one…. These were my props for my presentation.

I remembered that on the way from Kansas City To Columbia Missouri along Highway 70, there was a sign that said, 100 Miles or 160 Kilometers to Columbia. There was also one just outside Saint Louis going to Columbia that said the same thing. So, I added that to my presentation. This met the requirement of how the roadways were moving to the metric system.

When the presentation began, I began handing the jars to someone in the front row to pass around the class….. Yeah. A jar of dirt. A jar of rocks, and a piece of asphalt and the chunk of concrete. I remember our teacher, Mr. Wright grabbed the chunk of Concrete when I gave it to the guy in the front row and looking it over, then pointing to a spot on it and saying, “I can see the skid marks here where I almost hit you!”

Anyway. I ended the presentation by taking the chunk of concrete after it had been passed around the class and holding it up and saying that if we continued to create roads at the same pace that we have over the last 60 years, by the year 2076 the world will look like this…. And I held up the chunk of concrete. — Of course.. I had totally made that statistic up out of thin air. — I got an A+ for that project which was worth 1/3 of our grade for the semester.

End of side story.

So, here I was again, fourteen years later, and I was being told that I had a crew of guys standing out in the shop waiting for directions on how to pull cable from the Logic room just below the control room, across the T-G building and into the middle of the Office building on the top floor. Even though the Office was on the 3rd floor, it was equivalent to the 6th floor of an office building.

From experience, I knew that the cable would have to be pulled from the logic room down to the cable spreading room below the main Switchgear, through two manholes, then up through conduit to the office area above the break room kitchen and over to the Telephone room.

I had done nothing to prepare for this. I hadn’t looked through the blueprints to find the best route. I hadn’t even seen the large spool of wire on the pallet in the Main Switchgear waiting to be used. I hadn’t even prepared myself by looking confident like I knew what I was doing….

Bill walked out the door leaving me in the office with Charles. I wasn’t sure if Charles could tell that I was completely blind-sided by this job or not. But he did give me a quick “leg up”. He said, “Seems to me that there is already power going from the VSP (for Vital Services Panel) to the Telephone room.”

Well. I already knew that I was really lucky. Especially when I asked Saint Anthony to help me find a solution to a problem. So, I quickly glanced over in the corner where Saint Anthony liked to lean against the wall while he waited for me to come to my senses and have some faith. In my mind I could see Anthony shrug like, “sounds like you might give it a try.”

So, I walked… no… I strolled out into the shop like I belonged there….. — Oh… yeah. I did. But at that particular moment I didn’t feel like it, so I thought maybe if I walked like I did, it would help me feel that way.

I asked Scott Hubbard if he could help me check to see if we had power in the Telephone Room from the Vital Services Panel. He said he would be glad to help (this was Scott’s usual response. — A True Power Plant Man Response).

I asked him to go the Telephone room while I went to the Vital Service Panel for Unit 1 in the Logic Room. Scott took his handy Dandy Voltage Checking Tool and headed off toward the Office area.

I headed for the Logic Room with a pair of Fuse Pullers:

The Vital Service Panel is mounted on the wall next to the UPS (Uninterruptible Power Supply). I opened it and read the labels inside of the cover. After scanning the list of locations that were fed from this panel I found one that could have been the one circuit I was looking for.

It was cryptically labelled in pencil “Telephone Room”. Hmmm…. I wonder if this is it… My mind had quick as a snap decrypted this entry and came up with “Telephone room”. — That sure sounds like this would provide power to the Telephone room. Let’s just hope that it is labelled correctly.

I waited until Scott called me on the gray phone to tell me that he was in place by the Telephone room. He had checked all of the receptacles (plug ins) in the room, and they all had power on them.

I told him that I would remove the fuse to the circuit that looked like it provided power to the telephone room, so in about 15 seconds, he could check to see if any of the receptacles was dead. So, we did just that. I removed the fuse….. — My first thought was…. Good. I didn’t trip the unit. I would have known that right away. — You never know… pulling a fuse out of a panel labelled “Vital Services Panel” kind of leaves you to believe that the stuff in this panel is really really important.

I went back to the gray phone and waited for Scott to get back on the phone. About 15 more seconds and Scott returned. He told me that the power had turned off on one of the receptacles on the wall. I told him I was going to put the fuse back in and head up to the telephone room so that he could show me where it was.

Literally 20 minutes after I had been jolted awake by the revelation that I was supposed to lead a crew of contractors on a wire pull that I had not prepared for, I had found out that the wire was already there. No wire pull was necessary.

Scott showed me where the receptacle was, and we walked back to the electric shop. Bill Bennett was standing in the shop wondering where I had disappeared to (oops. ended the sentence with a preposition. I should know better than that. I should have said, “….where I went.” or “…why I had disappeared”).

I was still wondering in the back of my head if I had just completely forgot that Bill had ever told me about this, or maybe he had forgotten to mention it in the first place, or he had not told me on purpose just to see how I would react to the sudden revelation that I had a semi-difficult job with no time to prepare for it.

I waited for Bill to follow me into the electric shop office. Which he did. Standing there with as straight of a face as I could muster, I looked at Bill as he asked me when I was going to start pulling the wire. The Contractors are just standing around doing nothing.

I said, “The job is already done. The wire has already been pulled.” “What do you mean? It’s still in the switchgear on the pallet.” Bill responded. I shrugged and said, “We don’t need to pull wire from the Vital Services Panel. There is already a circuit from that panel to the telephone room.” I looked over at Charles and smiled. Charles smiled back. Bill said something like, “Oh… Then I wonder what we are going to do with these contractors. We have them for three days.” Then he left the office.

I thought that somehow Charles knew something about my being “setup for some kind of failure” and had this up his sleeve all along so that it would backfire. — Just my luck. With three of my best friends standing there, how could I fail…. Charles Foster, Scott Hubbard and Saint Anthony.

We had the contractors sweep out switchgears for the next 3 days.

Doing Dew Point Tests and Lowering Expectations

The 68th “Rest Of” Power Plant Post

Originally posted May 9, 2014:

There were times when I was working at the Coal-Fired Power Plant in North Central Oklahoma when I wondered if there was anything that we couldn’t do. Surrounded by True Power Plant Men I found that when we were facing a seemingly impossible task, a Power Plant Man would come up with an extremely creative solution to the problem.

One such example was during the “We’ve Got The Power” program. I talked about this program in an early post called “Power Plant We’ve Got the Power Program” so I won’t go into detail here about the program itself. I will just say that we broke out into teams to find creative ways to operate more efficiently, and to cut costs.

I was a team leader of our team, and looking back I must have had two criteria in mind when I picked the team members that would be on my team. The first would have been that they were True Power Plant Men (and woman) with a higher than average intelligence. The second criteria would have been that they were friends of mine. I say this, because everyone on my team fit the bill.

During out team meetings, Terry Blevins would often say some bombastic statement that the average person may be inclined to dismiss immediately as being absurd. I say that because I remember more than once thinking that what Terry had just said wouldn’t amount to much. As it turned out, our biggest money saving ideas were those truly bombastic statements that Terry was making. One such idea had to do with the heaters on the precipitators that kept the hoppers and the insulators on the roof too hot to collect moisture.

The Precipitator is a very large box that takes the ash out of the exhaust before it goes out of the smoke stack (how many times have I made that statement in the last two years?). Anyway, the exhaust from the boiler after the coal has been turned to ash in the fireball in the boiler contains a large amount of moisture. The last thing you want to happen is for the temperature of the flue gas to fall below the dew point. When that happens, moisture collects on the structure in a form of… well… of Acid Rain. Basically eating away the precipitator and the duct work from the inside.

Somewhere along the line, it had been determined that the dewpoint of the flue gas was not higher than 250 degrees. So, as long as the structure was at least 250 degrees, no moisture would be collected. Four heaters were mounted on each of the 84 hoppers (on each of the two precipitators) and heaters were mounted on the roof around each of the insulators that held up the wire racks on both ends.

When Terry walked into the office to attend one of our first “We’ve Got The Power” team meetings, he said, I think we could save a lot of money if we did something about the heaters on the precipitator. — He may remember being greeted with blank stares (at least from me). Um. Ok. Heaters on the precipitator. I knew they were everywhere, but I never gave them much thought.

I think Terry could tell right away that I hadn’t taken his idea seriously. I don’t know. Maybe he was bothered by the sound of my eyeballs rolling around in circles as if someone has conked me on the head. So, he explained his idea further. He pointed out that the roof heaters on just one of the precipitators used about 211 kilowatt-hours and the hopper heaters used about 345 kilowatt-hours. Together it is more than half a Megawatt of power. — This definitely caught our attention. That meant that between both of the Precipitators (since we had two boilers at our plant), we could possibly save over a Megawatt of electricity every hour we could shut down the heaters.

The plant has a similar electrostatic precipitator, only it is twice as long

The plant has a similar electrostatic precipitator, only ours is twice as long

After discussing all the aspects of the idea, we decided that in order for the idea to have any merit, we had to know if the dew point really was around 250 degrees, or was it possibly a lot lower. 250 degrees seemed high to begin with since the boiling point of water is 212 degrees. If lower, then we could have a workable idea. Originally, I wanted to tackle the task of finding the dew point. So, I went about it in a Science Experiment sort of way.

I figured that if we were able to lower the temperature of the flue gas to a known temperature below the dewpoint, and by knowing the volume of the gas, and the amount of liquid we could condense out of it, we could determine (possibly) the dew point. So, I brought my Graham Condenser to work, and Scott Hubbard and I went up to the 250 foot landing on the smoke stack with the intent of sucking a known amount of exhaust from the smoke stack while the unit was at full load.

We would run it through the condenser while running cool water through it to lower the temperature.

I could measure the output of the vacuum pump by filling up an inverted Erlemeyer flask with water and then letting the flue gas displace the water. — I always loved doing experiments like this in the 9th grade science glass with Mr. Godfrey our Physical Science Teacher (Donna Westhoff, who may sometimes read this blog was in my class and sat right behind me).

Ok. Side Story, since I mentioned Donna Westhoff from the 9th grade 1974-75 school year.

I knew that Donna’s father was a fire fighter, because one day during a special outing when we were with a group of bicycling Junior High School students and a teacher, we stopped at Donna Westhoff’s house to get a drink of water. On the walls in her house were different types of fire fighting treasures. Donna explained that her father was a fire fighter… That was the Spring of 1975 in Columbia, Missouri

Fast forward 16 years later (1991) at the Power Plant in the middle of nowhere in North Central Oklahoma. Just about a year after the story I’m telling now…. I left the logic room and went to catch the elevator to the Control room. When the doors opened, Tony Mena was in there with a bunch of college age students giving them a tour of the plant. I entered the elevator and turned around to face the door as it closed.

As I was standing there, I suddenly became aware that the person standing next to me was staring right at me. So, I turned to see who it was. Standing next to me was someone that looked very familiar wearing a big grin as if she knew who I was. I recognized her, and while my mind was going through filing cabinets of memories trying to index this particular person, I asked her, “Don’t I know you?” She shook her head and said, “I’m Donna Westhoff!”

As the elevator door opened and we stepped out, Donna and I began talking about what we were both doing there. She was surprised to find that I had become an electrician at a power plant instead of some kind of scientist in a lab somewhere. Donna was going to school in Stillwater where one of the best Fire Fighting Schools in the country is found.  Following in her father’s footsteps, I thought.

After a while I could tell that Tony was getting a little perturbed that the wisdom he was imparting about the fire protection system on the Turbine Generator wasn’t being absorbed by Donna, so I cut our conversation short. It turned out that a very good friend of hers lived just two houses from where we lived, and her friend’s mother was my landlord. Peggy Pickens (perfect name for a landlord).

Ok. End of the side story, and another example of how I occasionally run into friends from my childhood in the most unexpected places (see the post: “Relay Tests and Radio Quizzes with Ben Davis“).

So. Scott Hubbard and I tried using the Graham Condenser and the Erlenmeyer Flask, but we quickly found out that this wasn’t big enough, to capture a large enough quantity. So, we increased the size of the condenser by winding a garden hose around inside of a water bucket and filling it with ice. Then we captured all the water that condensed in the hose.

When it finally came down to it. Even though it was fun trying to do this experiment halfway up the 500 foot smoke stack, I never was able to figure out how to calculate the dew point given the data I had collected.

That’s when we decided to look at dew point sensors in the parts catalogs. If we could stick a probe down into the precipitator and measure the dew point directly in the flue gas, that would be best. After looking at a few in the catalog, Terry Blevins said he thought he could make one. So, he went to work.

The next day he came in with an inch and a half conduit with hoses hanging out the back and a homemade sensor on the other end. I won’t go into detail how the sensor was built because some day Terry may want to patent this thing because, as it turned out, it was so sensitive that it could detect my breathe from about a foot away. If I breathed out of my mouth toward the sensor, it would detect the moisture in my breath. This was perfect!

We went to work on the roof of the precipitator sticking the probe down into different sections of the precipitator. It not only measured the moisture, it also had thermocouples on it that we used to accurately measure the temperature of the sensor as we varied the temperature by blowing cold air through the conduit using the same ice bucket and hose from before.

I could go into a lot of detail about how we performed our experiments, but it would only excite me and bore you. So, let me just say that we came up with two very important results. First of all, at full load when the humidity outside was at 100% the dew point was around 150 degrees! A full 100 degrees below what the plant had originally assumed. This was very important, because a lot of energy was spent trying to keep the flue gas above 250 degrees, and just by lowering it down to 210 degrees, still a safe amount above the dew point, that extra energy could be used to create electricity.

The second thing that we discovered was that the middle sections of the precipitator was a lot cooler inside than the outer fields. We realized that this was caused by the air preheater coils that rotated between the flue gas and the Primary Air intake duct. This took the last amount of heat possible from the exhaust and transferred it to the air going into the boiler so that it was already hot when it was used to burn the coal. Because of the way the air preheater coils rotated, the part of the duct toward the middle of the precipitator was a lot cooler than the air on the outside.

Diagram of a boiler

Diagram of a boiler. See the Air Preheater? Flue Gas on one side and ambient air on the other

Lower temperatures in the precipitator increased the performance, so we decided that if we could mix the air around as it was going into the precipitator so that the outer edges were cooler, then it would increase the overall performance. One suggestion was to put a mobile home in the duct work because in Oklahoma it was a known fact that mobile homes attracted tornadoes and it would probably cause a tornadic reaction that would mix up the flue gases. — We just couldn’t figure out how to convince management to put a mobile home in the duct between the economizer and the precipitator.

Thanks to Terry’s handy dandy Dew Point Sensor, we were able to prove that the hopper and roof heaters could be lowered to where we set the thermostat at 180 degrees. At that setting the heaters that used to always run at 250 degrees would remain off anytime the ambient temperature was above 45 degrees. In Oklahoma, that is most of the year. This turned out to save over $350,000 per year in energy savings at a cost of about 1.5 cents per kilowatt-hour. Not to mention the unknown savings from being able to lower the flue gas temperature by 40 degrees.
