Description:
The paper provides information useful for woodstove designers concerned with reducing emissions. A dual-chamber woodstove was modified to induce secondary combustion by utilizing an ignition source and forced flow of secondary air. The ignition source was an electric glow plug installed in the secondary chamber. Secondary airflow was maintained at a preset flow rate and supply temperature. Wood was burned in the stove in a laboratory following a standard protocol, and the stack emissions were monitored continuously. The modified stove generally emitted less pollution than the same stove did prior to modification. Emission levels generally declined as the flow rate of secondary air and the supply air temperature were increased. Incorporating these modifications into a woodstove, with appropriate controls, represents an effective emission control technology.
