摘要
为满足国家环保对火电厂氮氧化物排放要求,以及在运机组采用"先降后脱"的脱硝指导思想,利用3号机组大修,完成了低氮燃烧器改造。通过主喷嘴局部改造,增加燃尽喷嘴;可以有效降低N0x排放,保证锅炉效率。
To fulfill the national requirement of nitrogen oxides emission and the denitration guidelines, the low NOx combustion of NO. 3 units had been reformed. Through the regional reformation of main nozzle and the adding of burnout nuzzle, the NOx emission had been decreased effectively, which ensured the efficiency of boilers.
