Atmospheric pollutant emission factors from open burning of agricultural and forest biomass by wind tunnel simulations. Volume 1. Final report
Technical Report
·
OSTI ID:445837
Atmospheric pollutant emission factors were determined by wind tunnel simulations of spreading and pile fires for 8 different types of fuel including barley, rice and wheat straw, corn stover, almond and walnut tree prunings, and Douglas fir and Ponderosa pine slash. Cereal straws and stover were burned in fires spreading against an impressed wind, pile burns in wood fuels were naturally ventilaled through the side doors. Emission factors were determined for each fuel for CO, NO, NOx, SO2, total hydrocarbons, methane, nonmethane hydrocarbons, total sulfur, CO2, particulate matter, volatile organic matter (VOC), and polycyclic aromatic hydrocarbons (PAH). Elemental compositions of particulate matter were determined by size category. Bulk aerosol absorption coefficients were determined from light transmission measurements through filter samples. Emission rates were correlated against burning conditions and fuel compositions. Factor affecting the burning rates and emission factors included inlet air temperature, loading rate, and wind speed.
