PROBLEM TO BE SOLVED: To provide a rotor temperature measuring method and device for a rotary machine capable of performing precise measurement of a rotor surface of the rotary machine for a long period of time when starting or a stopping the rotary machine, and to provide a steam turbine.SOLUTION: In a rotor temperature measuring method and device for a rotary machine having a rotor and a stationary body wall surface covering the periphery of the rotor, a non-contact thermometer such as a radiation thermometer is installed oppositely to the rotor surface, a stationary body thermometer such as a thermocouple is installed on the stationary body wall surface near the non-contact thermometer, a correction value for correcting the measured temperature of the non-contact thermometer is calculated using the measured temperature of the stationary body thermometer, the measured temperature of the non-contact thermometer is corrected using the corrected value, and then a rotor temperature of the rotary machine is obtained. |
