This volume describes emission results from sampling of flue gas from a firetube boiler burning a coal/oil/water (COW) mixture and COW with soda ash added (COW+SA) to control SO2 emissions. Measurements included: continuous monitoring of flue gas emissions; source assessment sampling system (SASS) sampling of the flue gas with subsequent laboratory analysis of the samples to give total flue gas organics in two boiling point ranges, specific quantitation of the semivolatile organic priority pollutant species, and flue gas concentrations of 73 trace elements; Method 5 sampling for total particulate; and controlled condensation system sampling for SO2 and SO3 emissions. Flue gas SO2 emissions decreased almost 99% with soda ash addition from 1,089 to 13.6 ppm (3% O2). NOx emissions decreased slightly from 477 to 427 ppm, while CO emissions increased significantly from an average of 25 to 426 ppm (all at 3% O2). Particulate loading at the boiler outlet almost doubled (from 1,970 to 3,715 pg/dscm) with the additive. The size distribution of particulate also shifted to a much smaller mean diameter. Total organic emissions increased from 6.7 to 13.1 mg/dscm; most of the increase were nonvolatile (C16+) organics. Of the semivolatile organic priority pollutant species, only fluoranthene and phenanthrene were detected with the COW fuel, and phenanthrene with the COW+SA fuel.
