Title:
タービン
Document Type and Number:
Japanese Patent JP4467949
Kind Code:
B2
Abstract:
Turbine comprises a rotatably mounted rotational-symmetrical rotor (2) having rotating blades (17) on its outer periphery toward which a working medium is directed, a cooling fluid produced by a compressor for cooling the guide blades (16) interacting with the rotating blades, and a channel connected to the rotor for cooling fluid. The cooling fluid in the channel is cooled by evaporating a liquid. An Independent claim is also included for a gas turbine (1) comprising the above turbine. Preferred Features: The channel runs along the rotor and is connected to the rotor so that the rotor is also cooled by the cooling fluid. The channel is an annular channel (20) formed coaxially to the rotor and having an inner side formed by the rotor surface.
