摘要： According to one embodiment, there is provided a single-flow turbine using CO2 as a working fluid. The turbine includes a balance piston portion configured to optimize an axial load of a rotor on a bearing with a fluid having a temperature lower than a temperature of the working fluid introduced into the turbine, wherein a flow path in which at least a part of the fluid passing through the balance piston portion is extracted from a middle part of the passing, and in which at least a part of the extracted fluid is urged to flow to a middle part of a passage where the working fluid passes and where rotor blades at a plurality of stages are provided, is formed at the turbine.

摘要： 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.
