Propane Evaporator Build
Hi all,thought I would post a bit about my DIY propane evaporator build (be nice now because I am not a fabricator by any means).
SS Propane Evap 1.jpg
Found this SS cart of sorts at a local auction during the summer and brought it home. I don't have a clue as to what it was used for. It's about 2'6" wide 5'6" long each of the squares you see are 2'x2'.

I put a couple of wheels on one end and a couple of rubber adjustable feet on the other for levelling the monster. The I cut one end open and stuck 3 propane weed burners in (each burner is advertised as going to 250,000 BTU) that's a total of 0 to 750,000 of adjustable BTU (insert Tim the Tool Man grunt here). Also built a gas manifold assembly everything hooks up to. While doing this work I found a couple of boxes of 24" W x 2" thick Ceramic Fibre insulation so I bought them and installed some into the interior.

Using a 2'x2' pan and a 1'xx2' pan (also auction finds) I did a proof of concept boil to see if it even would work. Low and behold we boiled water.
More to show but enough typing for the night
