摘　　要：为了防止600 MW机组锅炉启动阶段NO_(x)排放超标,降低启动成本,加快启动速度,通过提高锅炉给水温度、增加前烟道烟气流量、提前启动磨煤机及其他操作的调整,实现了非改造手段达到启动过程投脱硝的目的。In order to prevent excessive NO_(x)emissions during the start-up phase of the 600 MW unit boiler,reduce start-up costs,and speed up the start-up,by increasing the boiler feed water temperature,increasing the flue gas flow in the front flue,starting the coal mill in advance,and adjusting other operations,non-renovation methods have been achieved.The purpose of starting the process is to cast denitrification.
