Description:
The report gives results of comprehensive emission measurements and analyses for a 7.6 kg/s (60,000 lb/hr) watertube industrial boiler firing a coal/water slurry. Measurements included continuous monitoring of flue gas; quantitation of semivolatile organics and 73 trace elements; volatile organic sampling train (VOST) quantitation of volatile organic priority pollutants; EPA Method 5/8 for particulate and SOx; controlled condensation for SOx; Andersen impactors for particle size distribution; and grab samples for N sub 2 O. Emissions of NOx, SO sub 2, CO, and hydrocarbons averaged 510, 450, 285, and 1 ppm, corrected to 3% oxygen. Particulate emissions were 4.3 g/dscm, and particle size was biased to larger size fractions with over half of particulate mass at 10 micrometers or greater. Over 90% were 3 micrometers or greater. Combustible losses were high with over 40% carbon content in particulate. Total organic emissions were 15 to 17 mg/dscm with half in the C1 to C6 range. Naphthalene was the only semivolatile detected.
