摘要
简述了燃烧过程中NOx的生成途径、NOx生成与排放的影响因素,介绍了电站锅炉常用的空气分级燃烧、燃料分级燃烧及烟气再循环三种主要的低氮燃烧技术原理,分析了提高NOx控制效果的主要因素,讨论了提高NOx降低率的技术参数的最佳范围。
The routes of NO_x composing in combustion,the factors influencing the NO_x producing and emission as well as the development of low NO_x emission combustion technology are described.Three kinds of combustion technologies decreasing NO_x such as air-staged,fuel-staged combustion and flue gas recirculation are introduced in detail.The analyses on impact factors and options of their parameters are discussed.
