This report is a final one for a test program to evaluate the long-term effectiveness of combustion modifications on industrial boilers. Previous short-term tests had been performed on industrial boilers to determine the effect of combustion modifications on such air pollutant emissions as NOx, SOx, CO, HC, and particulate. The objective of this program was to determine if the combustion modification techniques which were effective for the short-term tests are feasible for longer periods. The report gives results of a 30-day field test of a 26.4 MW output (90,000 lb steam/hr) residual-oil-fired boiler using staged combustion air and low excess air to control NOx emissions. Results indicate that these combustion modifications are effective long-term NOx controls for this type of residual-oil-fired boiler. The as-found NOx concentration was 158 ng/J (281 ppm at 3% O2, dry). With staged combustion and low excess air firing, the mean NOx emission level was 110 ng/J (196 ppm at 3% O2, dry). Boiler efficiency increased by 0.7% under low NOx firing conditions.
