COOK STOVE ASSEMBLY

摘要

A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum.

主权项

1. A portable biomass stove comprising:
a main body including;
a shell, with a plurality of handles;an inner chamber forming a combustion chamber, said combustion chamber including;a lower combustion chamber for at least partially containing the biomass fuel and including at least one inlet for the passage of at least air into the combustion chamber, andan upper combustion chamber having at least one outlet for venting at least part of any combustion byproducts away from said lower combustion chamber; andat least one annular constriction positioned in said upper combustion chamber, said constriction defining an aperture through which combustion byproducts flow, and through which an open flame may extend, said annular constriction to redirect at least a portion of any combustion byproducts upstream of said annular constriction back into the open flame combustion, and to create a recirculation zone downstream of said annular constriction to increase residence time of said combustion byproducts and to redirect at least a portion of said combustion byproducts back into the open flame combustion extending through said annular constriction.
