I had built one of those forges just for Bill's use and some of you saw the info I brought to the event on construction, costs, and propane. Since several of these forges will soon be built by our members, I want to do everything I can to make sure that those uninitiated in the use of Propane fuel understand clearly how to use it safely. I tossed it into the air expecting to see it float away on the cold winter breeze, but instead it fell promptly to the ground. Facts about Propane 1.
Propane is a liquid in the cylinder, but is burned as a gas.
Propane gas must be tapped from the top of the cylinder. As the liquid propane cools, the pressure of the vapor above it drops. Overheating liquid propane will cause dramatic, and potentially catastrophic, increase in the pressure of the vapor above it. Most commercial cylinders have a pressure relief device. If this opens the cylinder will not explode, but it could vent the entire contents of the cylinder.
