The report gives results of field measurements made on a 200,000 lb/hr spreader stoker boiler. The effect of various parameters on boiler emissions and efficiency was studied. Parameters studied included overfire air, flyash reinjection, excess air, boiler load, and fuel properties. Measurements included gaseous emissions, particulate emissions, particle size distribution of the flyash, and combustible content of the ash. Gaseous emissions measured were O2, CO2, CO, NO, SO2, and SO3 in the flue gas. Sample locations included the boiler outlet, multiclone outlet, and electrostatic precipitator outlet. In addition to test results and observations, the report describes the facility tested, coals fired, test equipment, and procedures. Increasing the overfire air flow was found to reduce particulate emissions by 25%. Overfire air flow did not significantly affect NO emissions. A 30% reduction in flyash reinjection reduced particulate loading at the boiler outlet 40%, and reduced boiler efficiency 1.3%. At design capacity, the boiler emitted between 12.7 and 15.8 lb/million Btu particulate matter and 225-315 ppm NO at the boiler outlet.
