摘　　要：北京京能热电股份有限公司4号锅炉大修后采用燃尽风(OFA)与水平浓淡低NOx燃烧器相结合的低NOx燃烧系统。改造后氮氧化物(NOx)排放浓度有明显改善,下降幅度达45%～60%;并有效减少炉膛出口烟温偏差,将其控制在50℃范围内;在NOx排放量得到大幅度降低的同时,燃烧效率提高1%左右。Beijing Jingneng Thermal Power Co. Ltd. g boiler 4 adopted OFA and low NOx horizontal bias combustion burner after boiler overhaul. After rebuilt the NOx emission was lowered by 45% to 60% , the flue gas temperature deviation at the exit can be maintained below 50℃. The burning efficiency went up 1% while NOx emission got lowered a great deal.
