Abstract (en)
[origin: EP2180149A1] Provided is a steam turbine facility capable of suppressing the possibility of vibration occurrence and a drastic increase in facility cost, thereby realizing an increase in size of the facility, even if steam conditions of 650°C or higher are adopted. In a steam turbine facility including a high-pressure turbine, an intermediate-pressure turbine, and a low-pressure turbine, the high-pressure turbine is separated into a first high-pressure turbine part on a high-temperature and high-pressure side and a second high-pressure turbine part on a low-temperature and low-pressure side, the intermediate-pressure turbine is separated into a first intermediate-pressure turbine part on the high-temperature and high-pressure side and a second intermediate-pressure turbine part on the low-temperature and low-temperature side, the first high-pressure turbine part and the first intermediate-pressure turbine part are integrated to form a first integrated part, the second high-pressure turbine part and the second intermediate-pressure turbine part are integrated to form a second integrated part, at least any one of the rotors and casings of the turbines into which steam with a temperature of 650°C or higher is introduced are constructed by joining together a plurality of members formed from Ni-based alloy through welding.
