Title:
VENTILATION CONTROL SYSTEM OF ROTOR SUPERCHARGED GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2024/001147
Kind Code:
A1
Abstract:
A ventilation control system of a rotor supercharged gas turbine, the ventilation control system comprising an air compressor (8), a rotor housing (23), a rotor (48) in the rotor housing, and a turbine (9), wherein the rotor housing is provided with a ventilation inlet (24), a ventilation outlet (28), and gas outlets leading to the turbine; a bypass pipe (15) with intermediate cooler branches from an air delivery pipeline (11) connected to an air output end of the air compressor, and is in communication with a pre-ventilation inlet in front of the ventilation inlet; the ventilation outlet leads to the turbine via an air output and delivery pipe (31); and a low-temperature sensor (45) is mounted on an auxiliary air output pipe (44) of a low-temperature air outlet (40) on the rear side of the ventilation outlet. When the ventilation speed in a combustion chamber slows down to allow the medium-temperature working gas to be also discharged through the low-temperature air outlet, the low-temperature sensor will send out a signal to allow a normally closed venting valve (35) on a venting pipe connected to the air output and delivery pipe for venting accordingly, so that the ventilation speed in the combustion chamber returns to normal.
