摘要： It is possible to easily and rapidly slot a blade root of a final (last) turbine rotor blade into a blade groove on a turbine disc even when the plan-view shape of a shroud of the turbine rotor blade is complex. A turbine rotor blade (1) that is provided with a blade root (3) that is slotted into a blade groove formed on a circumferential portion of the turbine disc to hold the whole blade, a blade portion (4) that is exposed to high-temperature gas, a platform (5) that supports this blade portion (4), a shank (6) that connects the blade root (3) and the platform (5), and a shroud (7) that extends along the circumferential direction from the end of the blade portion (4) has a cut-out portion (8) cut out to a predetermined depth, either at the leading-edge or the trailing-edge of the blade root (3), along the lengthwise direction thereof from the end of the blade root (3) to an intermediate part of the shank (6).

摘要： 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.
