Thirty-Day Field Tests of Industrial Boilers: Site 5 - Gas-Fired Low-NOx Burner

摘要

This is a final report on a test program to evaluate the long-term effectiveness of combustion modifications on industrial boilers. During previous programs, short-term tests were performed on industrial boilers to determine the effect of combustion modifications on air pollutant emissions such as NOx, SOx, CO, HC, and particulates. The objective of this program was to determine if the combustion modification techniques which were effective for short-duration tests are feasible for a longer period. The report gives results of a 30-day field test of a 24.9 MW (85,000 lb steam/hr) water tube boiler with low-NOx burners. The 30-day test was conducted with the unit firing natural gas. The mean NO emission level was 33 ng/J with a geometric dispersion of 1.12 at the high load condition.
