600MW机组单台一次风机带磨运行的探讨

Operation of 600 MW Power Generator Set with Single Primary Fan Running with a Coal Grinder

１台一次风机发生事故时，整台机组需停止运行。但在一次冷热风道各增设１个风门后，在不停机的情况下，单台一次风机可以带磨煤机运行，不需要换机，有很大经济效益。

The failure of a single primary fan may cause the stoppage of the whole power generating set, but the addition of a ventilation door each in the cold and hot pipelines makes it possible for the single primary fan to run with the coal grinder while the whole power generating set is operating non-stop with considerable economic results.
