Title:
GAS TURBINE WITH GAS SEAL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2023/134177
Kind Code:
A1
Abstract:
A gas turbine with a gas seal component (200), comprising a rotating shaft (100), a gas compressor (800), a turbine (300), and a combustion chamber (400). The gas compressor (800) and the turbine (300) are sleeved on the rotating shaft (100). An exhaust end of the gas compressor (800) is communicated with an inlet end of the combustion chamber (400). A guide vane assembly (700) is provided at an outlet end of the combustion chamber (400). A gas seal component (200) is provided between the guide vane assembly (700) and the turbine (300), and the gas seal component (200) is in airtight connection with the guide vane assembly (700). A first air hole (210) is formed on the gas seal component (200). An air inlet of the first air hole (210) is connected to an air source, and an air outlet of the first air hole (210) faces the turbine (300). Air from the air source is sprayed to a corresponding receiving surface on the turbine (300) via the first air hole (210), so as to form an air curtain sealing between the gas seal component (200) and the turbine (300) around the rotating shaft (100). The first air hole (210) may be a stepped hole, and the small-aperture end of the stepped hole faces the turbine (300). According to the gas turbine, the gas seal component (200) is provided between the guide vane assembly (700) and the turbine (300), such that high-temperature fuel gas of the combustion chamber is prevented from entering the gas turbine, and stable operation of the gas turbine is facilitated.
