摘　　要：介绍了三菱公司新研发的M-PM超低氮燃烧器在珠海电厂2×700 MW亚临界锅炉的应用。M-PM燃烧器是在A-PM低氮燃烧器的基础上研发的,具有更好的着火和稳燃性能,降氮效果更佳。锅炉采用M-PM燃烧器改造后,在燃用神华煤满负荷运行时氮氧化物排放浓度由360 mg/m3降低到136 mg/m3,比改造前降低62%,同时解决了锅炉汽温偏低、烟气热偏差大和燃烧器摆角过高的问题,锅炉效率有所提高。The applications of Mitsubishi ultra-low NOx burner （the M-PM burner） in two 700-MW subcritical boilers in Zhuhai Power Plant are introduced in this paper. The M-PM burner is newly developed based on the A-PM low NOx burner by Mitsubishi, which is characterized as better ignitability, flame holding performance and impressive effect on NOx emission reduction. After boiler burner retrofitting, while the Shenhua coal is burned in the boiler, the concentration of NOx emission is reduced from 360 mg/m^3 to 136 mg/m^3, about 62% less than before. In addition, the problems of low boiler steam temperature, large heat deviation of flue gas and high operating angle of burner are solved, and the boiler efficiency is also improved slightly.
