Patent number: 10550698Abstract: A turbine 10 includes: a turbine rotor having a rotor main body including a hollow part into which a cooling fluid flows, and a plurality of rotor wheels arranged in an axial direction of the rotor main body and protruding from the rotor main body. A cooling-fluid introducing passage extending from the hollow part in a direction intersecting with the axial direction of the rotor main body is formed in the rotor main body so as to allow the cooling fluid in the hollow part to flow through the cooling-fluid introducing passage and then to flow around the rotor wheel to be conducted to the working-fluid flow passage. A flow-rate control plug regulating a flow rate of the cooling fluid flowing through the cooling-fluid introducing passage is disposed in the cooling-fluid introducing passage.Type: GrantFiled: September 8, 2016Date of Patent: February 4, 2020Assignee: Toshiba Energy Systems & Solutions CorporationInventors: Asako Inomata, Iwataro Sato, Hideyuki Maeda, Satoru Sekine, Kazutaka Tsuruta, Takeo Suga
