Cause analysis of large pressure loss in main steam valve system of 600MW steam turbine
Turbine valve discharge characteristic was tested to resolve the problem of high heat-consumption in one 600MW power plant and the result indicated that pressure loss between front and back main steam valve groups was too large.Loose valve seat of adjusting valve
too small flow area between valve seat and valve head
poor aerodynamic performance of main steam valve groups were main factors responsible for large damper loss.In the end
