The paper discusses laboratory tests of a modified, popular dual-chamber woodstove to determine its ability to reduce emissions. In dual-chamber stoves, the primary chamber is for fuel volatilization, and the secondary chamber is for combustion. The original stove was first operated at low, medium, and high burn rates to establish baseline performance. The stove was then modified to include an electrical igniter and a controlled flow of air to the secondary chamber and was tested again under the same conditions. Variables measured included gas stream temperatures upstream and downstream of the secondary chamber (which indicate secondary combustion) and exhaust stream concentrations of carbon monoxide and unburned hydrocarbons (which indicate emissions). The paper discusses the effectiveness of these modifications in sustaining secondary combustion and reducing emissions.
