Title:
BIAXIAL GAS TURBINE AND COOLING AIR SUPPLY METHOD FOR BIAXIAL GAS TURBINE
Document Type and Number:
Japanese Patent JP2005076569
Kind Code:
A
Abstract:
To provide a biaxial gas turbine capable of reducing thrust force working on a low-pressure turbine rotor of the biaxial gas turbine and to provide a cooling air supply method for the biaxial gas turbine.
In the biaxial gas turbine, equipped with the low-pressure turbine rotor and a high-pressure turbine rotor, there is provided a partition member for partitioning the low-pressure turbine rotor and the high-pressure turbine rotor in the rotor shaft direction. A space is formed between the low-pressure turbine rotor and the partition member, and the space is divided into at least two portions by a seal member in the radial direction of the rotor shaft. A passage for supplying air to the divided inner-periphery space is also provided .
