Thank Nolbert. The matter is quite important. When designing a stove, the average moisture content of the fuel actually used means the design must consider how to deal with it.
Generally speaking, the provision of preheating of secondary and even primary air is required as the moisture level goes up. If the wood is very dry, the preheating must be limited or eliminated to prevent excessive production of volatiles. The wood in the video seemed to be quite high in moisture content, looking at the flames and smoke arising. If you can get some samples weighed and dried (at about 105 C in a warming drawer of an electric oven) it would be helpful for everyone to know what people actually put into the stoves. Regards Crispin Crispin, Am not sure of the exact moisture content but from experience and making a wild guess its between 10 - 15%. For example women can go to the forest 1-2 days after it rained, pick wood and use it that same day! There are those that keep the wood above the fire place for some days (mostly those with a better income though).
