Dear Lanny >...I have made a new burner for the camp stove... >...to bring 6 liters of 60 degF water to a boil While it is hard to see it from here, I think you would benefit in system efficiency from a reduction in the fuel burn rate, so my calculator says. If you can get the amount of wood burned per minute cut in half I think the efficiency will rise. It depends a bit on the pot. Is it shrouded and how big is it? Shrouded, you might see a reduction in fuel used to boil 6 litres on the order of 30% which is a lot.
