摘　　要：为了降低超超临界机组的厂用电能消耗,从锅炉冷一次风母管将冷一次风通过DN450管道接入原有的微油助燃系统中,同时将原来微油助燃风机出口DN450的管道增加止回阀。一般情况下,冷一次风供风可满足锅炉要求,原微油助燃系统可退出作为备用,在夏季磨煤机全部开启或煤种质量较差时,一次风量不足,可启动原微油助燃系统。改造后的助燃系统能够实现安全运行,达到降低电能损耗的目的。In order to reduce the auxiliary power consumption of ultra supercritical units,the cold primary air is connected to the original micro oil combustion supporting system through the DN450 pipe from the main cold primary air pipe of the boiler,and a check valve is added to the DN450 pipe at the outlet of the original micro oil combustion supporting fan.The reformed combustion supporting system can realize safe operation and reduce power loss.
