Abstract
A combustion chamber may include an upper and a lower chamber. The chambers may be separable to aid in loading fuel and removing spent fuel. The cross-section of the upper combustion chamber may be less than the cross-section of the lower section. Charcoal or other biomass fuel may be added into the lower combustion chamber and may be supported by a grate. Oxygen may be fed into the combustion chamber through a plurality of apertures that may be substantially shielded from direct line of site of the fuel bed. The upper combustion chamber may further include an annular constriction, to aid in constricting the view factor between the cooking vessel and the fuel bed. The constriction may also aid in radiating energy back to the fuel bed.
