How come the portable stove article mentions nothing about pumping up the pressure in the stove with the little rod pump thing? Rmhermen 16:45 2 Jun 2003 (UTC)

I was just trying to get the heat transfer mechanism right. I think using a pump on a stove is a dangerous way to start it and the pump is one more thing to pack. (I'm a weakling.) Rich J 23:43 2 Jun 2003 (UTC)

I don't get it. You need pressure in the fuel canister to force the fuel out into the burner. With liquid fuel, you need to use a pump to generate this air pressure. -Smack 19:38, 30 Jul 2003 (UTC)
A pump is one way to do it. What you have to get up to the burner is flammable vapor (liquid would quench the flame). This may be done by filling the trench at the bottom of the burner neck with gas, lighting that and judiciously opening the valve. The trench flame heats the burner which heats the neck. When you open the valve the chimney effect takes over. If you filled the stove properly (ever wonder why the fuel port is not at the high point?) there is a lot of vapor just waiting to rise. This vapor is ignited by the flame from the trench. The plate on the top of the burner captures part of the heat, returns it via the burner to the neck and everything rolls along merrily (until you let it burn at high heat too long and the stove explodes).
