Problems solved by technology

[0005] In order to solve the problems that occur after the pulse detonation combustion chamber is replaced by the isobaric combustion chamber in the power generation power plant such as a ground gas turbine, such as the low conversion efficiency of detonation gas energy, the reverse transmission of detonation combustion wave pressure affecting the operation of the compressor, etc., the present invention Propose a gas turbine power generation device using the viscous force of pulse detonation gas to do work
Since the Tesla turbine does not have any blade structure, compared with the axial flow and centripetal turbines used in the existing power plant, the unsteady pulse detonation gas can be adaptively generated in the Tesla turbine in a transient viscous Energy conversion by means of force action, solving the problem of low energy conversion efficiency of axial flow and centripetal turbines for pulse detonation gas
At the same time, the present invention aims at the working characteristics of the pulse detonation combustion chamber, and proposes a pneumatic valve structure that can adaptively follow the change of the working frequency of the pulse detonation combustion chamber. By using the pressure difference between the intake air and the detonation combustion wave back-transmission pressure difference, the automatic Open and close the pneumatic valve to solve the problem of detonation combustion wave pressure back propagation affecting the operation of the compressor

Description

Technical field [0001] The invention relates to a gas turbine, in particular to a gas turbine power generation device that utilizes the viscous force of pulse detonation gas to perform work, and is applied to convert low-quality fuel heat release internal energy into high-quality electric energy. Background technique [0002] Slow-burning combustion is a combustion method that heats the combustible mixture through heat conduction, thermal diffusion, and thermal radiation and causes a chemical reaction. The flame propagation speed is small, often less than 1m / s. At present, power plants such as ground gas turbines, naval gas turbines, aero engines, and missile engines often use isobaric combustion chambers based on the slow combustion method. During the fuel combustion process, the gas pressure in the combustion chamber is basically unchanged or slightly reduced, and the performance of this type of power plant has developed to a relatively mature stage. The ideal cycle thermal ef...
