This is a video of how to make a wood gas stove. A wood gas stove uses to stages of combustion. Stage 1 converts the wood to a gas, and stage 2 combustion the gas with the help of addition high temperature oxygen (or air) inlet near the gas combustion zone. The gas combustion zone is above the wood combustion zone.

Note, in the video, the two sets of vent holes—one set at the bottom of the outer (bean) can and one set at the top of the inner (soup) can. The bottom vent holes inlet air for both stages of combustion; a fraction of the inlet air passes directly into the bottom of the inner can and is used for combustion of the wood (stage 1), while the reaming fraction of the inlet air is heated as it passes up between the walls of inner and out cans, and finally through the top vent hole of the inner can. This is the high temperature air is what drives the stage 2 combustion process.

Some models use a small fan to “force” inlet air. Wood-gasification is one of the cleanest forms of combustion because it not only combusts the wood, but it subsequently combusts the gas produced from the initial combustion of the wood. This gas usually contains several pollutants, so when the gas is combusted, many of the pollutants get destroyed. Also, these stoves produce extremely high temperatures and are therefore very efficient.

Commonly referred to as wood gasifiers or wood-gas stoves.
