Abstract

The invention relates to a high-efficiency and low-pollution core engine, and relates to a gas turbine. The high-efficiency and low-pollution core engine is provided with a wave rotor, a pipeline, a fuel inlet and a flameless combustion chamber, wherein the wave rotor comprises a rotor, an air inlet end port plate and an outlet end port plate; the air inlet end port plate and the air outlet end port plate are correspondingly arranged at two sides of the rotor; parallel air channels are arranged in a circle on the rotor; a wave rotor air inlet and a reflowing smoke inlet are formed in the air inlet end port plate; a high-temperature low-oxygen mixed gas outlet and a smoke outlet are formed in the air outlet end port plate; the wave rotor air inlet, the reflowing smoke inlet, the high-temperature low-oxygen mixed gas outlet and the smoke outlet are used as inlets and outlets of gas medium; the rotor is rotated relative to the air inlet end port plate and the air outlet end port plate so as to regularly open and close an inlet and an outlet of a rotor channel; the pipeline is connected with the wave rotor and the flameless combustion chamber to form a flowing channel through which the reflowing smoke entering the pipeline can be mixed with air to generate high-temperature low-oxygen mixed gas; the fuel inlet is formed in the pipeline or / and the flameless combustion chamber.

Description

technical field [0001] The invention relates to a gas turbine, in particular to a high-efficiency and low-pollution core engine. Background technique [0002] As the "power source" of modern manufacturing industry, the gas turbine is continuously optimized with the needs of technological development, and a new type of wave rotor technology has been born. The wave rotor can replace the original high-pressure compressor, high-pressure turbine and shaft in the gas turbine, and has the advantages of reducing fuel consumption, increasing unit power, improving thermal efficiency and reducing weight, and does not require major changes to the original gas turbine. The development pointed out a new way. The operation of the wave rotor requires complete separation of the air and the combustion products, but in actual operation there will inevitably be mixing, which reduces the working efficiency of the wave rotor. [0003] As countries around the world pay more and more attention to...
