Emission Factors for Abrasive Materials
PMresp. metal concentrations and for developing the emission factors. The emission factors for Cr, Mn, Ni, and Pb were calculated using Equation 1. Equation 1 EFi = ER/m = [(Vi * Ci) /10 3]/ m where: EFi = emissions factor of metal pollutant i associated with PMresp., mg/kg-abr. ER = emission rate, mg/min Vi = air flow rate, m3/min

2. An “S” accompanying an emission factor means that this factor is the weighted average sulfur content of the fuel burned, expressed as a percent. See, for example, SCC 1-01-004-01 on page 14.A-3. If the weighed average sulfur content of the Grade 6 oil burned were three percent (3%), then the SOx emission factor would become 157 x 3,
