[摘 要]
为响应国家环保政策,莱城发电厂对#3锅炉进行了低氮燃烧改造,以实现氮氧化物排放浓度降低的目标.炉前脱硝技术（LNB)有多种,但目前普遍采用的只有一种——空气分级燃烧技术.在锅炉实际运行过程中,其低负荷稳燃、烟温调整、结焦状况等与配风有极大关联.

In response to the state environmental protection policy,lae of # 3 boiler of power plant low nitrogen combustion,to achieve the goal of nox emission concentration is lower.Before the furnace denitration technology (LNB) there are many,but there is only one widely used at present,the air gradation combustion technology.In the process of boiler operation,the steady combustion under low load,the smoke temperature adjusting,the condition of coking is strongly associated with air distribution.
