Title:
GAS TURBINE INCLUDING COOLING SYSTEM PROVIDED WITH COOL-AIR SUPPLY PATH DETOURING TO OUTER CASING
Document Type and Number:
WIPO Patent Application WO/2017/010627
Kind Code:
A1
Abstract:
The present invention relates to a gas turbine that includes a cooling system provided with a cool-air supply path detouring to an outer casing and, more specifically, to a gas turbine that includes a cooling system and a cooling method in which a cool-air supply path is not provided in the central shaft of the rotor of the gas turbine, but is configured to detour to the outer casing of the gas turbine to supply cool air to a plurality of turbine blades and other devices provided within the gas turbine, thereby exhibiting an effect of raising the aerodynamic efficiency of a compressor and the turbine. Thanks to the structure and method, the cool-air supply path can be configured to detour to the outer casing of the gas turbine, instead of being provided in the central shaft of the rotor of the gas turbine. In conclusion, this may help to raise the aerodynamic efficiency of the compressor and the turbine.
