Embodiment Construction
[0020] An injection intercooled gas turbine, including a compressor casing, multi-stage compression, RSS steady-flow burner, turbofan casing, and multi-stage turbofan, is divided into four parts connected end to end, and each part is formed by the same straight line Axis, left and right symmetrical;
[0021] The first part is composed of the first stage compressor casing, the first group of multi-stage compression, the first ejector, and the second ejector; the first group of multi-stage compression is located in the first stage compressor casing, and more than 2 The ejectors are distributed outside the compressor shell of the first stage; the front end of the multi-stage compression is connected with the air to be compressed, the front ends of the first ejector and the second ejector are connected with the cold air, and the rear end of the multi-stage compression The end communicates with the rear end of the first ejector and the second ejector to form an air inlet, and the a...

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 [0001] The invention belongs to the technical field of gas turbines, and in particular relates to an ejector intercooled gas turbine. Background technique [0002] The air intake of a traditional gas turbine is compressed by several stages of compressors, and the intake temperature rises. Due to the limitation of the gas temperature by the turbofan, the air pressure after the compressor cannot be too high, thus limiting the heat conversion efficiency in the combustion chamber. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the high intake air temperature limits the heat conversion efficiency in the combustion chamber, and proposes an ejector intercooled gas turbine. [0004] Technical scheme of the present invention: [0005] An injection intercooled gas turbine, including a compressor casing, multi-stage compression, RSS steady-flow burner, turbofan casing, and multi-stage turbofan, is divided into fou...
