Abstract
The invention discloses an ejection intercooling gas turbine. The ejection intercooling gas turbine comprises a gas compressor shell, multistage compressors, an RSS steady-flow combustor, a turbofan shell and multistage turbofans. The ejection intercooling gas turbine is divided into four portions, i.e. a first portion, a second portion, a third portion and a fourth portion which are in end-to-end connection communication, and are of bilateral symmetry through taking the same straight line as the axis; the first portion consists of a first section of the gas compressor shell, a first group of multistage compressor (3) and an ejector (1); the second portion consists of a second section of the gas compressor shell and a second group of multistage compressor (4); the third portion consists of the RSS steady-flow combustor (5); and the fourth portion consists of the turbofan shell and a group of multistage turbofan (6). According to the ejection-intercooling gas turbine, under the flowing ejection action of multistage compressed air, cold air enters an air inlet passage by passing through the ejectors, so as to be mixed with the compressed air and cool the compressed air, and then the highest combustion temperature is reduced, so that the compression pressure can be further increased, and the heat conversion efficiency is improved.
Description
Technical field
The invention belongs to gas turbine technology field is and in particular to cold gas turbine in a kind of injection.
Background technology
What compressor compression traditional gas turbine inlet air passes through, and intake air temperature rises, by turbofan, fuel gas temperature limited, after compressor, air pressure can not be too high, thus limiting the indoor thermal transition efficiency of burning.
Content of the invention
The purpose of the present invention limits burning Indoor Thermal transformation efficiency precisely in order to solving the problems, such as that intake air temperature is high, and proposes cold gas turbine in a kind of injection.
Technical scheme：
Cold gas turbine in a kind of injection, including compressor casing, multi-stage compression, RSS steady-flow combustion device, turbofan casing, multistage turbofan, is divided into four parts communicating that join end to end, each several part is all with same straight line as axle, symmetrical；
Part I, is made up of first paragraph compressor casing, first group of multi-stage compression, the first injector, second injector；First group of multi-stage compression is located in first paragraph compressor casing, and the injector of more than 2 is distributed in outside first paragraph compressor casing；This multi-stage compression front end and contact air to be compressed, first injector, the second injector front end are connected with cold air, the rear end of this multi-stage compression is connected with the rear end of the first injector, the second injector, forms air intake duct, and air intake duct is connected with Part II；
Part II, is made up of second segment compressor casing, second group of multi-stage compression；Second group of multi-stage compression is located in second segment compressor casing；This multi-stage compression front end is connected with Part I rear end, and rear end is connected with RSS steady-flow combustion device front end；
