Abstract

The invention relates to a blade wheel pressurized rotor jet turbine, with high working efficiency. Wherein, said invention comprises: an air compressor (1), a fuel gas mixing and transmitting unit (2), a burning work unit (3), a main axle (4), a front axle box (5), and a back axle box (6); it is characterized in that: the fuel mixed gas of burning work unit (3) will pass through the ignition reflective column (30) at the front of rotor (25), and the three-grade active wheel at the front of ignition reflective column (30); and it arranges cycle channel for cooling oil inside each element of burning work unit, to cool the elements effectively; the fuel gas will be ignited at the instant that ejected from the guide blade of rotor in high speed; the high-temperature high-pressure high-speed airflow will function on the active wheel and rotor to work; the kinetic energy generated by burning process can be fully utilized, to improve the efficiency.

Description

technical field [0001] The invention relates to a gas turbine. Background technique [0002] During the working process of a traditional gas turbine, the combustible gas is burned in a fixed combustion chamber, and the high-temperature and high-pressure gas generated is sprayed from the fixed nozzle to the blades at high speed, and the blades drive the impeller to rotate, and then complete the work process. In this process, the work flow The kinetic energy of the steam turbine has not been fully utilized, so there is a problem of low working efficiency of the steam turbine. Contents of the invention [0003] In order to solve the problem that the kinetic energy of the working air flow in the working process of the prior art is not fully utilized, and the existing steam turbine has low working efficiency, a kind of impeller pressurized rotor injection gas turbine is provided, and the combustible gas flows from the guide vanes of the rotor The moment of high-speed ejection ...
