Formula
Notes Units are lb of pollutant/ton of wood waste burned. Emission factors are based on wet, as-fired wood waste with average properties of 50 weight% moisture and 4500 Btu/lb higher heating value. Emission factor represents measurements from wood waste combustors equipped with PM controls (i.e., fabric filters, multi-cyclones, ESP, and wet scrubbers). Emission factor is for total dioxins, not toxic equivalents. Excludes data from the combustion of salt-laden wood. For salt laden wood, the emission factor is 1.300E-6 lb/ton with a ""D""rating.
