Abstract: Disclosed herein are systems and devices that aid in reducing particulate emissions from biomass stoves, for example by the use of gases injected in or near the oxidation zone of a combustion chamber. Also disclosed are systems and devices providing electricity to a pump or blower that aids in injecting the gas and/or collecting exhaust gases. In some embodiments the device providing electricity is a thermoelectric generator that may also be used to power other devices. In many embodiments, the systems and devices inject a gas at or near the oxidation zone in the combustion chamber of a biomass stove. The gas injected into the zone may be fresh air, exhaust from combustion or combinations thereof. The gas can be forced into the to combustion chamber with the aid of a pump or blower that may also aid in drawing in exhaust gas.

Abstract: The present disclosure is directed to new ferritic alloys comprising iron, chromium, and silicon. The novel alloys have surprisingly enhanced corrosion resistant properties, with excellent workability, strength, and ductility. The disclosed alloys, and products made therefrom are useful in making low cost, efficient, and clean biomass stove combustors, as well as other devices for use with biomass fuel.

Abstract: 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.
