摘　　要：论述了燃煤电站锅炉低NOx燃烧技术的原理,系统介绍了电厂大机组锅炉所采用的低NOx燃烧系统,比较了现有的低NOx控制技术方法及其应用情况,为低NOx燃烧设备的选择提供参考。1 000 MW燃煤电站锅炉烟气脱氮系统运行结果表明,从燃烧过程中控制NOx的生成量,有利于实现NOx的达标排放,能大幅度降低电站锅炉烟气脱硝系统的投资和运行费用。The basic principle of low NOx combustion technology was first discussed. Then the low NOx combustion equipment used in big thermal power unit boilers is introduced. The technology of low NOx combustion and its application in the practical projects were compared in detail, which can provide a reference for choosing this kind of equipment. The data of flue gas De-NOx system running in 1 000 MW thermal power unit boilers show it is not only benefit to realize NOx zero discharge at emission control regulations but also largely reduce investment and running cost of flue gas De-NOx system in power boilers that controlling NOx output in combustion process.
