zak54 Posted January 20, 2019 Share Posted January 20, 2019 Hi Guys, In the process of converting a 20lb propane cylinder into a forge. The dimensions before Kaowool are 9" by 12". Allowing for 2" Kaowool I worked the volume out to be 8"x9" = 452.39 cu inches. How will a single burner perform in a forge of this volume? I've read that there should be one 3/4" burner per 350 cu inches so I fall short....will just the one burner have a significant difference on my forging ability? Not into forge welding at this stage. Any help would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
VainEnd84 Posted January 21, 2019 Share Posted January 21, 2019 There is a pinned post that I believe answers this Also what about refractory coatings? Ceramic fibre blanket with out ridgidizer or a castable is a big no for safety, there is a pinned post about that as well. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted January 21, 2019 Share Posted January 21, 2019 It depends partly on the burner, but any 3/4" burner, running reasonably well, should do just fine in that size forge, so long as you follow all the recommendations about insulation, finish coatings, exhaust openings, and limiting secondary air; just simple common sense about forge construction.
