In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Twin Boilers - One Pipe Steam System
Out with the old, in with the new. We'll be staging on temperature and pressure. The original 5" header was kept in tact, and only modified for the new drop-in boiler risers. The old boiler water line was about 12" taller than the new boilers, leaving all of the wet returns exposed to steam, so we had to choose between stacking the boilers on top of 5 cinder blocks, or creating a false water line...we chose the false water line.
You'll notice the Knucklehead Inc. piping job on the boiler. They went from 4" at the boiler, down to 2-1/2", then back to 5" at the header. STEAM SYPHON!
Here are some photos of the first day.
