低NOx燃烧控制在超超临界锅炉中的应用

Application of Low NOx Emissions in Combustion Control in Ultra-supercritical Boiler

阐述了酸雨的危害及产生的原因,结合发电厂超超临界燃煤锅炉燃烧系统的特点及机组168 h调试结果,说明通过将煤粉进行分段燃烧,以达到降低燃烧时锅炉NOx的排放;并着重介绍了其具体的实现控制方法和采用这种方法所最终达到的低NOx排放的燃烧效果。

This paper first explains the harm of acid rain and the causes, combine with the characteristics of ultra supercritical boiler burning system and 168 h commission results of unit,indicating the staged combustion pulverized coal to the boiler combustion to reduce NOx emissions; and highlights the specific method to achieve control and using this method to achieve the ultimate low NOx emission combustion.
