Abstract:

The process and features of startup through intermediate pressure(IP)cylinder of two 600MW units in some power plant project phase I were presented.The faults occurred in the process of startup through IP cylinder were analyzed in detail, and the relevant treatment measures were proposed. At last, it was pointed out that the tartup through IP cylinder is a safer and more economic way for unit startup.
