sfDuck Posted March 30, 2009 Share Posted March 30, 2009 Hi fellas, I have this idea for a new, cheaper, gas forge. Instead of propane or natural gas, Methane ! I know, this is going to STINK ! But not if the gas burns with a hundred percent effeciency. The oriface size of the burners will have to be changed from propane to nat. gas, because propane uses to much pressure, and this will be a low pressure forge to be safer. The only drawback is that it needs two people to run it. But because of the low cost of fuel it will be most effecient. Of course the fuel lines can still be soft copper, with brass Flare fittings as they are the safest to date. A pezzo lighter for the main burners is a must though. And from my research it shows that Methane burns HOTTER than Propane, so the heating up period is a lot less. Anyway here is a drawing of the mock up, take a look and see if you can come up with any improvements. I'm sure there will be plenty so thanks in advance for all your suggestions. -----Duck Quote Link to comment Share on other sites More sharing options...
viking-sword Posted March 30, 2009 Share Posted March 30, 2009 Excuse me, but(no pun intended), a good propane burner will run on only 3 to 5 pounds of pressure, and I "Know" most of us here can muster up way more than that, and I'll bet a sizable amount of forging can be done before the fuel supply runs out.:):) Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 30, 2009 Share Posted March 30, 2009 Also, the proper ratio for air:methane is 10:1 so pressure is a lot less important. I think you're a natural for this Duck. Frosty Quote Link to comment Share on other sites More sharing options...
