I thought you used a Remington kiln gun and MasterBlaster ammo for that job?
I used to work in a power generating plant, coal-fired. It wasn't bad 95% of the time. But to clean the boilers out when they are offline usually involved huge heavy denim monkey suits with face masks. It involved climbing into small holes barely as big as the distance from the inside of my elbow to my wrist. Very tight fit. Dragging an air hose with a three foot nozzle on the end. Oh, and a drop light, because it's completely pitch black.
Once inside, one tried not to get stuck, break the light, and run the nozzle between the water pipes to blow slag off that gets stuck on them. OH, did I mention the huge induced draft fans are on? To suck the debris out, of course, but there ya are in a wind tunnel, I'm guessing 40 mph air roaring through. This would break the light occasionally, as it floated around in there. The only communication with coworkers was tugging on the airhose.
This takes about an hour or so. Then one tries to wriggle back out, backwards. Then you roll over, and go back in to do the other side.
This took all morning. That took care of one access hole. There are several. Per boiler. It's a good thing I wasn't claustrophobic.
Washing soot out of your hair took four or five shampoo/lather/rinse cycles.
But I understand why so many of the maintenance people went out of their way to put on weight. They'd get too fat to fit.
I've done that too!
