I've put in an embarrassing number of cash and hours trying to build my own
furnace. At this point it's an obsession and if anyone here can help I'd be
so very appreciative. I'm quite sure I'll be leaving out critical details
but having blown my whole weekend on a new design that was yet another
failure I fear a full description might end up in a rant! Let me know any
specific info you'd need.
I have a high pressure manual regulator rigged to a burner based on this
I've used every combination of upwind/downwind and pipe size combo's you can
imagine. And read many web sites, many. The part that feeds the furnace
(end of the pipe) is 3/4" metal blackpipe angled offcenter, etc. The outlet
hole in the lid is about 1.5" across. The issue is that as soon as I place
the lid on, the flame either goes out or comes out the top creating a very
dangerous gas buildup in the furnace so that when I remove the lid, POOF
major dangerous flamage.
Can you not cover a propane furnace? If I rig the same burner config to a
3/4 to 1 flare it works great and in the open oven just fine.....but I can't
get this thing anywhere near hot enough to melt silver and (LOL) have burned
up almost a whole tank of propane with failed designs.
Any help is appreciated.
