摘　　要：文中通过对309台燃气锅炉的烟气初始排放数据进行统计分析,结果表明:燃气锅炉NO_(x)平均排放浓度为98.6mg/m^(3),NO_(x)合格率为91.91%;为降低氮氧化物的生成与排放,建议采用低氮燃烧器、空气分级燃烧、全预混表面燃烧、烟气再循环及增设尾部脱硝装置等措施。Through the statistical analysis of the initial flue gas emission data of 309 gas-fired boilers,the results show that the average NO_(x)emission concentration of gas-fired boilers is 98.6mg/m^(3) and the qualified rate of NO_(x) is 91.91%.In order to reduce the generation and emission of nitrogen oxides,measures such as low nitrogen burner,air staged combustion,fully premixed surface combustion,flue gas recirculation and tail denitration device are recommended.
