Abstract

PURPOSE: To automatically and accurately warm up a turbine by repeating, until the temperature at a high-pressure steam conducting part reaches a target value, intermittent switching movements of a high-pressure emergency stop valve and a drain exhaust valve while a high-pressure main steam control valve is closed.
CONSTITUTION: A high-pressure emergency stop valve 51 and a high-pressure main steam control valve 77 are provided in a high-pressure steam system, and a low- pressure emergencey stop valve 27 and a low-pressure main steam control valve 15 are provided in a low-pressure system, and also, a thermocouple 88 is provided at a high-pressure steam conducting part. The high-pressure emergencey stop valve 51 and the drain exhaust valve 82 are switched at a certain intervals while the high-pressure steam contrl valve 77 is closed to warm up the high-pressure steam part and to exhaust drain. These movements are repeated until the measured temperature of the thermocouple reaches a target value. By such constitution, a steam turbine can be automatically and accurately warmed up.
