Evaluation of Methods for Physical Characterization of the Fine Particle Emissions from Two Residential Wood Combustion Appliances
KINSEY, J. S., P. KARIHER, AND Y. DONG. Evaluation of Methods for Physical Characterization of the Fine Particle Emissions from Two Residential Wood Combustion Appliances. ATMOSPHERIC ENVIRONMENT. Elsevier Science Ltd, New York, NY, 43(32):4959-4967, (2009).
The fine particulate matter (PM) emissions from a U. S. certified non-catalytic wood stove and a zero clearance fireplace burning Quercus rubra L. (northern red oak) and Pseudotsuga menziesii (Douglas fir) cordwood each at two different moisture levels were determined. Emission testing was performed using both time-integrated and continuous instrumentation for total PM mass, PM number, particle size distribution, and fixed combustion gases using an atmospheric wind tunnel, full-flow laboratory dilution tunnel, and dilution stack sampler. A comparison made was made between the three dilution systems and two sampling filter types. The total PM mass emission factors for Teflon filter sampling of stove emissions in the wind tunnel varied from –2 to 8 g kg–1 of dry fuel depending on wood species whereas the equivalent fireplace wind tunnel emissions averaged 11 g kg–1 for the burning of wet oak. Important differences in emission factors were also observed between the three dilution systems and two filter types evaluated. A substantial number of ultra fine particles in the accumulation size range were observed during all tests with PM–2.5 (particles.≤ 2.5 μ m in aerodynamic diameter) fractions ranging from 93-98% (mass) depending on appliance type. An empirical relationship was also developed for all appliances and fuels which predict the total PM emissions based on combustion efficiency and fuel moisture.
