Default A Little Bit Of Plasma Cutting..............

today’s projects involves a little bit of plasma cutting, a little bit of welding, some mag drill work, and some geometry ciphering. I had to make a couple of burner adapters for a couple of boilers going into a sewage treat facility, up on the Canadian border.

The boiler manufacturer, made a mistake and made the front wall opening for the boiler about 3 inches too big in diameter, the mounting flange bolt center, in now inside their hole, so I had to make 2 adapters to not only be able to mount the burner on the front of the boiler, but also move the burner 1-1/2” further back from the front wall to gain some extra clearance. I started out with (2) 24” x 24” x 1/4” plate, along with (2) 11” OD x 8” H x 3/16” rolled rings, ending up with (2) 17-1/2” OD x 11-1/2” x 1/4” flange rings with the rolled rings welded to them.

I also had to make (2) 20” OD x 12” ID x 3/8” flat rings, with (12) 3/4” holes on a 17” bolt circle, to end up being welded into the roof of the boiler casing to give us not only a stack outlet flange, but also a stiffening ring to stiffen the 24” x 24” x 3/16” outlet panel. Normally the stack is supported off of the ceiling supports, but in this case the roof will support the first 15-20 feet of the 12” doubled walled stainless steel stack, before the ceiling supports can used.

Looks like you will be needing a new chart that you can read on the side of the tool box.

Yes and sort of,


Yep, one is set up to burn methane, both are capable to burn natural gas, if no methane is available, both are used to make hot water, used for building heat and also the hot water heats part the sewage treatment process

Looks nice. Did you cut the circles with some sort of guide or freehand? I have been thinking of making a circle tool for my cutter but still kinda on the fence if it is worth doing.
