Whats the point of fans in stoves?
Combustion requires a few key elements: 1. fuel (provided by wood, which is evaporated into gases (‘wood gas’) during combustion); 2: heat (initially provided by a spark or match, and subsequently by combustion itself), and 3: oxygen. Open fires are innefficient because they are oxygen starved just where all the fuel and heat is. Fan- and convection-assisted gasifier stoves inject warm air into the heart of the combustion, so giving the wood gas an opportunity to fully combust.
