Ralph is right. They work much like a Coleman stove. We had one of these when I was a kid. Ours was designed to use gasoline, preferably white gas, but we always used regular gasoline. You would fill the tank, and pressurize it with the built in pump. Ours had a screw on the underside of the burner that you loosened to let raw gas drip into the pan under the burner. When the pan was almost full, you closed the screw and set the pan on fire. When the gas in the pan was almost completely burned you would open the burner valve. The burner assembly would be then be hot enough to vaporize the gasoline coming through the burner. BT

Here in the Ozarks, we still have the remnants of the charcoal making industry. The kilns in this area look like concrete Quonset huts with large steel doors on the end. Several truck loads of cordwood, mostly oak and hickory, are loaded into the kiln and set on fire. The doors are closed and sealed with mud. There is a small vent in the top of the kiln to let the gas escape. The fire will burn for several days and take several days to cool. Several years ago, during a particularly dry summer, a trucker was hauling a load of fresh charcoal from a kiln to a briquet factory. The load hadn't completely cooled yet. When the trucker took off, the load caught fire, spewing burning charcoal and starting fires along a 10 mile stretch of country backroads. BT
