适用循环流化床锅炉的脱硝技术

The denitrification technology for circulating fluidized bed boiler

循环流化床锅炉由于低排放在我国应用十分广泛,但如果不采取措施已不能满足目前的环保要求。介绍了NOx的产生机理,通过几种脱硝技术的对比,指出循环流化床采用低氮燃烧+SNCR脱硝技术是很好的选择。

Circulating fluidized bed boilers are widely used in our country due to its low pollution emission.The quality of flue gas cannot meet the current emission limit if there are no environmental protection facilities. The mechanism of NOXformation is briefly introduced in this article.Through the comparison of several denitrification technologies, it shows that the low NOXcombustion ＋SNCR technology is a better choice for the circulating fluidized bed boilers.
