| Abstract: | The impacts of the abnormality in vacuum system on large steam turbine unit are analyzed with examples, such as the flaw in joint face of turbine LP cylinder, exhaust hinder of vacuum pump, air leakage of condenser, steam leakage through the gland sealing system of steam turbine and feed-water pump turbine etc. The methods of solving these problems are introduced. Some suggestions on technology management of power plant are proposed. |
