摘　　要：控制电力生产过程中NOx生成量的方法主要是分级燃烧.选择国内具有代表性的300 MW燃煤电站锅炉为对象,对锅炉不进行改造,在不同负荷条件下,利用分级燃烧原理,通过炉内优化分级燃烧试验,得出了降低炉内NOx生成的控制参数.额定负荷时,炉内NOx排放浓度在原有基础上降低了22.45%,有效地控制了NOx的排放.There are many adopted. A typical coal-fired methods to control NOx 300 MW utility boiler is in which air-staged combustion is popularly chosen, with structure unchanged different loads, Using staged-combustion principle, through optimized staged . Under the -combustion experiment, control parameters to reduce NO, formation are obtained, Under the rated load, NOx emission is decreased by 22.45 percent. NOx emission is controlled effectively.
