摘　　要：随着中国现代工业的大规模发展和城市化进程的加快,工业锅炉、电站锅炉和民用锅炉的使用量随之增加,特别是工业锅炉的数量逐年增多且传统锅炉逐步更新换代为集成化数字智能化控制的新一代锅炉,随着各类燃烧锅炉数量的增多,锅炉燃烧排放烟气中N、S元素污染物对大气环境的污染问题逐渐凸显。介绍从源头控制降低锅炉烟气排放中氮氧化物(NO_(x))的方法,兼顾提高锅炉的热效率,使锅炉燃烧排放系统在最少的燃料及最低源头控制降低NO_(x)排放状态下得到最高的热能利用效率,达到节能减排目的。With the development of modern industry and the acceleration of urbanization in China,the use of industrial,power station,and domestic boilers has increased accordingly.Especially,the number of industrial boilers has been growing year by year,and traditional boilers are gradually being replaced by a new generation of integrated,digital,and intelligent control systems.As the number of combustion boilers increases,the pollution of atmospheric environment by N and S element pollutants in the flue gas emissions from boiler combustion has become increasingly prominent and cannot be ignored.This paper introduces the method to control and reduce NO_(x) emissions from boiler flue gas at the source,and to improve the thermal efficiency of the boiler.This approach aims to achieve the highest thermal energy utilization efficiency with the least fuel consumption and the lowest NO_(x) emission reduction at the source,thereby achieving the goal of energy saving and emission reduction.
