摘　　要：煤炭的高效洁净燃烧是实现洁净煤发电的一个重要领域,是洁净煤发电技术的核心。而循环流化床燃烧技术是一种新型的煤燃烧与发电技术,不仅可以大幅度减少NOx排放,易于脱除SO2的技术优势,而且具有煤种适应面广、高燃烧效率以及炉内脱硫脱氮的特点而得到推广。分析了循环流化床锅炉NOx的危害、生成机理及影响因素,在此基础上探讨了其控制措施,并提出未来烟气净化的方向。High-efficiency clean coal combustion is the key technology for clean coal power generation. The circulating fluidized bed （CFB） is a new type of coal combustion and power generation technology. Using this technology, NOx emissions can be reduced significantly, and SO2 emissions can also be controlled easily. The CFB can adapt to a wide range of coal and operate with a high combustion efficiency. In addition, furnace desulfurization and denitrification can be realized by the CFB. This paper analyzed the NOx formation mechanism and influencing factors on the circulating fluidized bed boiler. The NOx control measures and the future direction of flue gas purification were discussed.
