Title:
COOLING DEVICE, GAS TURBINE INSTALLATION PROVIDED WITH SAME, AND METHOD FOR OPERATING COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/178418
Kind Code:
A1
Abstract:
A cooling device (60) is provided with a high-temperature-component cooling system (70) for guiding air to a high-temperature component (41) of a gas turbine (10). The high-temperature-component cooling system (70) has a compressor (77) capable of operating independently of the gas turbine (10), and air inside a cylinder (16) of the gas turbine (10) is guided to the high-temperature component (41) after being extracted from the cylinder (16) and pressurized by the compressor (77). The cooling device (60) is also provided with a rotor cooling system (80) for extracting the air in the cylinder (16) out from the cylinder (16) and guiding the air to a turbine rotor (51), and a connecting system (90) for guiding the air pressurized by the compressor (77) to the rotor cooling system (80) while fuel supply to the gas turbine (10) has stopped.
