Dear Stovers We all seek to minimize fuel consumption for a given task, and that in effect means maximizing the efficiency, probably under varying heat output conditions.
I have seen little consideration of the fact that nitrogen in the air goes along for a free ride, but reduces the efficiency because you have to heat up the free rider along with everything else. It is for this reason that the Excess Air Ratio tells you so much - it tells you if you have enough air to combust properly, and not too much to waste heat on nitrogen (and other inerts in the atmosphere like argon and CO2). You can gain quite a lot in efficiency if you control the excess air as the fuel is consumed in a normal batch burn, and once you have learned how to control it you can find ways to implement that control - which is the really exciting part of stove design.
