Abstract

Experiments were performed to investigate the characteristics of combustion of 7MW-3 air stages combustion system for a heavy oil firing boiler. Several fuel nozzles were developed for the purpose of lowering pollutions in another institute and ${\Phi}$-jet nozzle among them was equipped to the combustion system. A variety of combustion phenomena were observed as air stage ratio, air fuel ratio and load are changed for each nozzle. Main combustion characteristics are shape of flame, NOx and CO generations, smoke scale number. Through lots of adjustments, the combustion system reaches such goals as the low NOx of 160 ppm, CO of 300 ppm corrected at $O_2$ of 4% and dust of 150 mg/Sm3.
