摘　　要：介绍了几种低NO_X燃烧器的技术特点以及炉内空气分级燃烧的机理及其影响因素，为修改制定大型贫煤锅炉NO_X排放标准及大型锅炉优化设计与运行提供了科学依据。On the basis of NO_X formation mechanisn．low－NO_X burners and air stage combustion are discussed．The optimization of low NO_X emission combustion measures in a 300 MW lean coal furnace are carried out firstly by using the numerical simulation methodand an optimum air ratevelocity and position for the OFA are obtainedThereafter a new NO_X emission control regulations and combustion modification measures with high efficiency and low NO_X emission for the large utility-type lean coal boilers are put forward．
