□(1) A temperature detector installed in the low-pressure exhaust chamber of the steam turbine detects that the temperature of the low-pressure exhaust chamber has become higher than the upper limit predetermined temperature T1°C, and the low-pressure exhaust chamber spray valve receives the detection signal. The temperature sensor detects that the temperature in the low-pressure exhaust chamber has become lower than the lower limit predetermined temperature T2°C, and upon receiving the detection signal, the temperature controller closes the low-pressure exhaust chamber spray valve. In a low pressure exhaust chamber spray device equipped with a mechanism, an upper predetermined temperature T. The circuit that opens the low pressure spray when the temperature is higher than ℃ is provided with a timer that operates to keep the low pressure exhaust chamber spray valve open for a predetermined period of time even if the temperature of the exhaust chamber becomes lower than the lower limit predetermined temperature T2''C. A low-pressure exhaust chamber spray device characterized by: (2) Timer setting time c-i 1o~
The low-pressure exhaust chamber spray device according to claim 1, characterized in that the spraying time is 30 minutes.
