Description:
The paper gives results of work to develop and demonstrate, in the laboratory, NOx reduction techniques that would be suited to petroleum refinery CO boilers. (Note: Most refineries have one or more CO boilers to incinerate off-gases from catalytic cracking. These devices constitute a significant fraction of total refinery NOx emissions. Methods used to reduce NOx emissions from conventional boilers either are not applicable or have performed poorly when applied to refinery CO boilers.) The program had three major objectives: (1) to simulate in the laboratory a full-scale refinery CO boiler, (2) to investigate the effects of operational variables on NOx formation in the boiler furnace, and (3) to evaluate combustion modification techniques to reduce the NOx emissions.
