    Patent number: 10646824
    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.
