I've been back in the States for just under a week, and finally have the gumption to write the last post for the most recent trip to Germany. I must say that coming home to see family once again was met with great anticipation, two sleepless nights, and a wonderful smooch from my wife at the airport. I sure do appreciate the fact that she came to DIA in order to meet me after a long trip and a late flight (we didn't land until midnight). Seeing her and the kids is my secular Christmas. The last time I came home at the end of November 2011, I was greeted with the following: Alan Jackson singing "Remember When," (one of my favorite songs about the future (hopefully)) and this ~
It sure made the pain of being away intensify and quickly melt away. Sure made things seem to be more worth it. I guess that is what made leaving for Germany at the start of January so tough. That and the fact that I was going to be returning to Germany in short order after getting back. Supposed to be going back to Niederaußem this Saturday, BUT it turns out that I've been redirected to Texas next week. Then I am off to Rizhao, China and Yeoungheung-do, South Korea. For those of you jonesing for posts from the "other side of the sandbox," your wish is my command. Thank you to Will Kent for showing me how to get around the Chinese censors.
So, visits to Niederaußem and Neurath generating stations finished up the last trip. Four boilers in three days. Noooo problem, right? Riiight?!? Shit no. At least the drive into these places was nice, Neurath is to the right and Niederaußem is to the left:
Neurath turned out to be a fairy easy visit. Had to field-repair the temperature controller in the MDC, align some sensor heads, and diagnose a failed sensor head. Please check out the posts on Keystone, if you haven't the foggiest notion what I am talking about and your interest is piqued. Moderate troubleshooting at Niederaußem Unit G and a rather easy walkabout around Niederaußem K were the "highlights," of our visit to Niederaußem. However, Unit D was a whole new beast. My hard hat is off to the install team. Not sure how they did it, but they did. Amazing work by Scott and Glen. Allow me to elaborate...
There are these thingies at German power plants called overfired air ducts. True, these things are at American plants, but they are different in Germany. Think of this system as the EGR system on a car: Exhaust gas is redirected into the combustion zone for better combustion and improved emissions out the exhaust (allegedly). Here is a picture of what is inside of these pipes:
The protective glass is broken, so you can see the 2000+ F "air," glowing orange-hot inside this pipe. The pipe has a wall thickness of maybe a foot, so it is radiating much heat. In order to get to three of our pitch sensors, one has to climb up, over, around, and through scaffolding, pieces of scaffolding, these hot pipes, a buckstay (I-Beam), and wooden planks. Not much fun to say the least. I thought I had slayed the fear of confined spaces. Turns out not so much. I actually had to ask Glen to move out of my way in order to get myself under control. Nearly freaked out. Here is where I was standing when I did:
I'm standing at sensor 3, and had to move between the boiler wall (left), overfired air (right), and an I-Beam to get to sensor 4. The width was about half my body's width, and I would have had to Army crawl under that I-Beam to get to #4 (which you can kinda see in the background). Needless to say, the walls closed in quickly, with the accompanying tightness in the chest, racing heartbeats, and major pucker factor happening you know where. Glen was kind enough to move when I said that I needed to get out. After spending a few minutes outside to get myself under control again, I made a second attempt at getting to #4. This time I looked for a way to get there from the other side, by #6. This is where the over, under, and around trek takes place. I counted 8 sequences of going up and down in order to reach #4 and #5 sensors. Twasn't much fun, even after the 8th trip. Here is a picture of Glen working on sensor #4:
The round pipe to the left is the overfired air duct. Being away from family is very difficult, and working in these conditions amplifies it even more. Let's see, we work in other tight places: There's the "Tunnel of Love," at Ottumwa, "Frying Pan," at Amos, "Hell," at Cane Run, and "The Pits," at Clay Boswell. I'll try to get pictures of these places the next time I'm there. I guess we can call the front wall of Niederaußem Unit D "WTF???" As in what were they thinking??? I guess we'll go anywhere to get our job done, all in the name of customer satisfaction.
Talk to you later from Texas.
Thank you for reading,
Kevin
