COOLING SYSTEM FOR GAS TURBINE, GAS TURBINE EQUIPMENT PROVIDED WITH SAME, AND COMPONENT COOLING METHOD FOR GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2016/121684
Kind Code:
A1
Abstract:
A cooling system (60) is provided with a high-pressure bleed line (61) for bleeding high-pressure compressed air (A1) from a first bleed position (Pb1) of a compressor (10) and sending the air to a first high-temperature component (44a), a low-pressure bleed line (64) for bleeding low-pressure compressed air (A2) from a second bleed position (Pb2) of the compressor (10) and sending the air to a second high-temperature component (54b), an orifice (65) provided to the low-pressure bleed line (64), a connecting line (66) connecting the high-pressure bleed line (61) and the low-pressure bleed line (64), a first valve (67) provided to the connecting line (66), a bypass line (68) connecting the connecting line (66) and the low-pressure bleed line (64), and a second valve (69) provided to the bypass line (68).
