Abstract

The invention relates to the technical field of gas turbines, and discloses a gas turbine system. The gas turbine system involves a gas turbine and a supercharging unit; the gas turbine comprises a first gas compressor, a combustion chamber and a turbine assembly, wherein the combustion chamber is provided with an air inlet, a gas inlet and an exhaust port, a gas outlet of the first gas compressorcommunicates with the air inlet, a gas outlet of the supercharging unit communicates with the gas inlet, the exhaust port of the combustion chamber is provided with an exhaust pipeline, and the turbine assembly is arranged on the exhaust pipeline and comprises at least two stages of turbines arranged in the flowing direction of gas in the exhaust pipeline; and the pressurizing unit comprises a second air compressor and a pressurizing driving turbine used for driving the second air compressor to act, and an air inlet of the supercharging driving turbine communicates with a part between two adjacent stages of turbines in the turbine assembly through a drainage branch. According to the gas turbine system, the problems that an existing gas turbine usually adopts a system configuration mode of"gas compressor and gas turbine", so that the occupied area is large, and the cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a gas turbine system. Background technique [0002] There are a lot of low-pressure or normal-pressure gas in production and life, such as: biomass gasification synthesis gas, coal gas, biogas, gas, etc., using this kind of low-pressure low-calorific value gas as fuel for power generation and heating is an important aspect of micro gas turbines. application market. The gas turbine system requires the inlet pressure to meet specific requirements. For example, the gas inlet pressure of a micro gas turbine is usually in the range of 6-15bar. Therefore, if a micro gas turbine uses low-pressure gas as fuel, the gas must be increased. pressure. [0003] In the prior art, the system configuration of "gas compressor + gas turbine" is usually adopted, that is, the gas compressor is used to pressurize the low-pressure gas. However, the price of a gas compressor usually accounts for...
