摘　　要：近几年随着火电机组年利用小时不断降低,燃煤电厂机组启停次数也在逐年增加,机组在启动阶段(并网初期)由于锅炉工况限制NOx排放量会超标。本文针对此问题进行深入研究,并提出切实可行的措施,以期达到降低机组启动阶段NOx排放的目标。With the decrease of annual utilization hours of thermal power units in recent years,the starting and stopping times of coal-fired power plants are also increasing year by year,in the start-up stage(initial stage of grid connection)NOx emission will exceed the standard due to the limitation of boiler working conditions.In this paper,in order to achieve the goal of reducing NOx emission in the startup stage of the unit,this paper makes an in-depth study on this problem and puts forward practical measures.

关 键 词：超超临界机组 NOx控制 启动过程
