摘　　要：详细分析了煤粉燃烧的特点及其燃烧产物NOx的生成机理,从实用性与高效性上,对各种目前研究与应用的控制切圆煤粉燃烧锅炉的低NOx排放技术,如低NOx直流煤粉燃烧器、空气分级、再燃和尾部烟气脱硝等进行了介绍,联系运行的实际情况进行比较分析。The combustion during combustion were disc but also high efficiency, the characteristics of pulverized coal and the formation mechanism of NOx ussed in this paper. From the point of view of not only real application low NOx emission technologies apllied on the tangential firing pulverized coal combustion boiler, such as low NOx emission direct-flow burner, air staging, reburning and flue gas removal etc. were introduced connected with their experience.
