Title:
GAS TURBINE AND COMPONENT-TEMPERATURE ADJUSTMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/090709
Kind Code:
A1
Abstract:
A gas turbine (1) is provided with a compressor (10), a turbine (30), a bleed line (61), and a component introducing line (66). The bleed line (61) extracts, as bleed air, compressed air from an intermediate compression stage (19a) of the compressor (10) and guides the bleed air to a first component (44) that constitutes part of a turbine casing (41). The component introducing line (66) guides the bleed air that has passed through the first component (44) to a second component that is a component constituting the turbine (30). The second component is a low-pressure component (47) that is disposed in a lower-pressure environment than the pressure of the compressed air at an outlet port of the intermediate compression stage (19a).
