Abstract:

Abstract:Taking the 670 MW supercritical coalfired unit of a company as example, the reason of high fault rate of steam turbine pneumatic drain valve was analyzed.The targeted fault treatment method was given, and preventive measures were proposed. Originally, the faults occurred 16 times in unit startstopduration in average.After the treatment measures were implemented, the faults occurred 2. 5 times in unit startstop durationin average. The treatment result is favorable.
