Description:
The report gives results of a project, in support of the intergared Air Cancer Project (IACP), to provide data on the specific effects of appliance type and operating variables on woodstove emissions. samples of particulate material and volatile organic compounds (VOCs) were collected. Particulate samples were analyzed for different organic fractions including specific polynuclear aromatic hydrocarbon (PAH) compounds. Inorgatiic matter on the filters was also analyzed. Results were calculated for pollutant concentrations, emission rates, and emission factors. Twelve test runs were conducted on a conventional stove, and two on a catalyst equipped stove. Operating variables included fuel type (oak and pine), altitude (80 and 800 m), and burn rate (high and low). Test data were analyzed using analysis of variance and linear regression procedures. Although the data do not show strong statistical significance due to variability of results, some general trends do appear to be present, and conclusions can be drawn as to the effects of various operating variables on woodstove emissions. At the 99% confidence bound (CB), oak fuel reduced emissions of total PAH compounds relative to pine fuel. Emissions of carbon monoxide (CO) showed a significant decrease from low to high burn rates, and a small decrease when oak, rather than pine, is used.
