<p>Turbine, especially a gas turbine, comprises along a rotatably mounted rotational-symmetrical rotor (2) a compressor, a combustion chamber (5) and a turbine part consisting of several turbine stages (15). Each turbine stage has interacting rotating blades (17) and guide blades (16) which are surrounded by hot working medium (13). The turbine also comprises a cooling fluid produced by the compressor for cooling the blades, which flows in a channel along the rotor from the compressor to the turbine part and in which a liquid is introduced for cooling. The channel extends outside the rotor and the liquid is introduced into a region in the channel near the compressor. An Independent claim is also included for a gas turbine (1) comprising the above turbine. Preferred Features: The channel runs along the rotor and the rotor is cooled by cooling fluid. The channel is an annular channel (20) formed coaxially to the rotor and containing cooling fluid.</p> |
