WIPO Patent Application WO/2016/143103
Kind Code:
A1
Abstract:
A turbine (10) is provided with: a turbine rotor (40) having a rotor body (41) having a cavity (42) into which cooling fluid (cf) flows, the turbine rotor (40) also having a plurality of rotor wheels (46) arranged in the axial direction (ad) of the rotor body and protruding from the rotor body; and a plurality of impeller blade rows (50) each supported by a corresponding one of the rotor wheels, the plurality of impeller blade rows being driven by working fluid (wf) flowing through a working fluid flow passage (wp). The rotor body has formed therein a cooling fluid introduction passage (60) extending from the cavity in the direction intersecting the axial direction of the rotor body. The cooling fluid in the cavity flows around the rotor wheels and/or between two adjacent rotor wheels after flowing through the cooling fluid introduction passage and is conducted to the working fluid flow passage. A flow rate adjustment plug (70) for restricting the flow rate of the cooling fluid flowing through the cooling fluid introduction passage is disposed in the cooling fluid introduction passage.
