摘要
目前火力发电仍然占据我国电力生产的主导位置,而火力发电厂的燃煤锅炉带来的环境危害已经日益严峻。文章主要论述了氮氧化物的产生机理以及危害,并且结合燃煤锅炉的特点介绍了几种低NO_x燃烧技术,经过对比分析可知,优化燃烧装置,提高工艺能效将成为燃煤电厂实现低NO_x排放的关键。
At present,thermal power still occupy the dominant position of China＇s power production,and the environmental hazards which coal-fired boilers of thermal power plant produce have become increasingly serious. This paper mainly discusses the generate mechanism and harm of nitrogen oxides,and introduces several low NOxcombustion technologies in combination with the characteristics of coal-fired boilers. Through comparative analysis,it can be seen that optimizing the combustion device and improving the process efficiency will be the key to achieve low NOxemission in coal-fired power plants.
