| Abstract: | The abnormal shut- off of main steam valve for subcritical 600 MW steam turbines threatens safe operation of the unit, being a difficult problem harassing every related power generation company. According to the severity, the abnormal shut- off of main steam valves has been classified. By analysing structural features of the main steam valves and the stress of their key parts, an approach to the causes resulting in various kinds of abnormal shut - off for main steam valves has been made, and measures for solving the said problem being put forward. |
| Keywords: | sub- critical 600 MW steam turbine main steam valve abnormal shut- off |
