INFLUENCE OF THE OIL SECONDARY AIR ON THE FLOW AND COMBUSTION CHARACTERISTICS IN A 300 MWE DOWN-FIRED BOILER
IntroductionAt present, down-fired combustion technology is one of the techniques applied for burning this fuel. However, practical down fired boiler operation suffers from problems of high carbon content in the fly ash and high Nox emissions. It is difficult to maintain a stable flame, especially when the load is low.1 Up to the 1960s, down-fired boilers were used to burn low-grade coal in Spain.2 Burdett carried out industrial tests to investigate the effects of air staging on Nox emissions from a 500-Mwe down-fired boiler unit.3 Fan et al. And Liang et al. Carried out numerical research into Nox formation in the furnace of down-fired boilers.4. However, up to now, in down-fired boilers, no measurements of gas temperature and gas species concentrations at several ports of the furnace have been reported.
