摘　　要：为解决W火焰锅炉炉膛温度高、NOx排放量非常大等问题,通过数值模拟等方法,对W火焰锅炉的低氮燃烧、SNCR、SCR宽负荷联合脱硝改造方案的可行性进行了论证,并将改造方案应用于湖南大唐某电厂600MW锅炉机组。改造效果表明,低氮燃烧、SNCR、SCR联合脱硝技术结合了LNB、SNCR、SCR各自的优点,在保证烟气中NOx排放达标的前提下,能尽可能地提高经济性。故它非常适用于W火焰锅炉机组。Due to the high NOxemission of W-shaped flame boiler,which is caused by the high furnace temperature.The feasibility of the joint denitration retrofit scheme of low nitrogen combustion,SNCR and SCR wide load for W-flame boilers is demonstrated by the numerical simulation method,and the reconstruction scheme for a 600 MW boiler in a power plant in Hunan Datang.Results show that the denitrification technology combined LNB,SNCR and SCR,which combined the advantages of these three technologies,can reduce the denitrification system＇s operation cost while the emission limits is met,and is very suitable for application in W-flame furnace.
