摘要:
A steam turbine of an opposed-current single-casing type has a high pressure turbine part and an intermediate-pressure turbine part housed in a single casing. A dummy ring partitions the high-pressure turbine part and the intermediate-pressure part, and a cooling steam supply path and a cooling steam discharge path are formed in the dummy ring in the radial direction. Extraction steam or discharge steam of the high-pressure turbine part, whose temperature is not less than that of the steam having passed through a first-stage stator blade, is supplied to the cooling steam supply path. The cooling steam is fed throughout the clearance to improve the cooling effect of the dummy ring and a turbine rotor. The cooling steam is then discharged through a cooling steam discharge path to a discharge steam pipe which supplies the steam to a subsequent steam turbine.

In a steam turbine 40 of opposed-current single-casing type in which a high pressure turbine part 31a and an intermediate-pressure turbine part 32a are housed in a single casing, a dummy ring 10 partitions the high-pressure turbine part 31a and the intermediate-pressure part 32a and a cooling steam supply path 101 and a cooling steam discharge path 103 are formed in the dummy ring 10 in the radial direction. Extraction steam or discharge steam s1 of the high-pressure turbine part 31a whose temperature is not less than that of the steam having passed through a first-stage stator blade 8a1, is supplied to the cooling steam supply path 101. The cooling steam s1 is fed throughout the clearance 721 and 723 to improve the cooling effect of the dummy ring 10 and a turbine rotor 7. The cooling steam s1 is then discharged through the cooling steam discharge path 103 to a discharge steam pipe 44 which supplies the steam to a subsequent steam turbine.
