Abstract

The invention provides a simple cyclical gas turbine based on rotary detonation combustion. The simple cyclical gas turbine based on the rotary detonation combustion comprises a gas compressor, a rotary detonation combustion room, a thermojet priming tube, an ejector, a mixing set, a turbine, a load and a cold source. The rotary detonation combustion room is applied to the simple cyclical gas turbine, and the mixing set is added at the tail part of the combustion room to ensure that working medium at an inlet of the turbine does not overheat. Through utilizing the pressurizing characteristic of the rotary detonation combustion room, the power capability of the working medium at an inlet of the turbine is improved, and under the conditions that the temperature, the efficiency of assembly unit, the pressure ratio of the gas compressor are uniform, the circulation heat efficiency of the gas turbine is improved 5%-10%.

Description

technical field

[0001] The invention relates to gas turbine technology, in particular to a simple cycle gas turbine based on rotating detonation combustion. Background technique

[0002] The thermal efficiency of the gas turbine cycle is the most important performance index to evaluate the technical level of the gas turbine design. The ways to improve the thermal efficiency of the gas turbine include the following points: increase the initial temperature of the gas and cooperate with the optimal pressure ratio. If the temperature is increased by 10 degrees Celsius, the increase in efficiency will become more and more limited; if the air extraction volume of the compressor is reduced, the compressed air consumed for cooling the turbine blades, cooling the disc and blade root, heat insulation of the case, and balancing the axial force will account for approximately About 20% of the air volume at the inlet of the compressor, if the exhaust air volume at the outlet of the compre...
