Abstract
A catalytic cookstove, for use in cooking, heating, and lighting, is disclosed for reducing particulate matter and carbon monoxide emissions. A non-platinum group metal catalyst promotes oxidation of particulate matter and carbon monoxide to produce carbon dioxide. Additionally, a passive damper automatically adjusts the fuel-to-air ratio based upon the size of fuel fed to the stove to ensure catalyst light off.
Claims24
A solid-fuel burning stove comprising:
- a stove body defining a combustion chamber;
- the stove body comprising an inlet adapted to receive solid fuel, the inlet being disposed substantially at a base of the combustion chamber and the inlet defining a passage for the intake of air and fuel into the chimney;
- and
- a catalyst coated substrate comprising a PGM-free, catalytic compound and adapted to permit the flow of exhaust gases therethrough and to expose the catalytic compound to the exhaust gases, the catalyst coated substrate being disposed substantially across the width of the combustion chamber.
