Combustion chamber for charcoal stove

摘要

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.

1. A biomass combustion chamber comprising;
an upper combustion chamber; a lower combustion chamber, wherein
the lower combustion chamber includesa grate for supporting a fuel bed, said fuel bed for accepting a solid fuel,a plurality of air flow apertures for allowing oxygen into the combustion chamber, wherein the apertures are substantially shielded from the direct line of site of the fuel bed, andthe cross-section of the upper combustion chamber is less than the cross section of the lower combustion chamber; and a slab and a slab cap, wherein the slab cap further comprises a lip and flange for aiding in shielding the apertures from direct view of fuel positioned in the fuel bed, wherein the upper combustion chamber and lower combustion chambers are separably engaged at a respective lower rim and upper rim; and the upper combustion chamber further defining a cone shaped funnel structure in direct line of site of the fuel bed.
