| Abstract: | Aiming at the problem of No.6 steam turbine over speed in a power plant,analyzes theaccident and finds out the reason. The analysis result shows that high temperature oxidiztion skinproduced between intermediate pressure regulating valve bush and valve cylinder to influence theregulating valve automatic close is the main reason of the steam turbine over speed. |
