1. steam/air cooling system that is combined into one that is used to have the combustion gas turbine of turbine spindle comprises:

  • The rotating turbine stage of a pair of axially spaced-apart, each grade has the turbines blade in some gas flows that are disposed at the described turbine of flowing through and has and be positioned at the impeller that is used to install described turbine blade around the described axle, respectively has at least one internal channel to the described blade of small part;

    Also has the gas compressor that is arranged at spacing means, firing chamber, the firing chamber controller that also therewith rotates between the turbine stage and has porting;

    Nozzle level between described turbine stage comprises somely, is disposed at the nozzle blade in the gas flow of the described turbine of flowing through;

    Has at least one internal channel to the described nozzle blade of small part;

    It is characterized in that;

    Cooling air is supplied with described internal channel by described blade and the nozzle level device with the described turbine of air cooling;

    Steam is supplied with described internal channel by described blade and the nozzle level device with the described turbine of steam cooling;

    Described steam supplier comprises the passage that is positioned within the turbine, as the stream passageway that a described turbine blade and nozzle level are communicated with other turbine blade and nozzle level,Be used to coordinate described cooling air supplier and steam supplier, to realize the conditioning unit of transition between described turbine of air cooling and the described turbine of steam cooling.
