Gas turbine generator and control method

Abstract

The invention relates to a gas turbine generator. The gas turbine generator comprises a rotating shaft, a first radial bearing, a motor, a second radial bearing, a Tesla compressor, a combustion chamber, a Tesla turbine and a third radial bearing; the rotating shaft sequentially passes through the first radial bearing, the motor, the second radial bearing, the Tesla compressor, the Tesla turbine and the third radial bearing; a gas inlet of the Tesla compressor is communicated with the outside; an exhaust outlet is communicated with a gas inlet of the combustion chamber; an exhaust outlet of the combustion chamber is communicated with a gas inlet of the Tesla turbine; an exhaust outlet of the Tesla turbine is communicated with the outside; and the first radial bearing, the second radial bearing and the third radial bearing are non-contact bearings. The equipment adopts the Tesla compressor and the Tesla turbine, and a rotor system is supported by the non-contact bearings, so that the integrated efficiency of the gas turbine generator is improved.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a gas turbine generator and a control method thereof. Background technique [0002] A Tesla turbine is a bladeless turbine driven by the shear force of a fluid, it is called a bladeless turbine. The Tesla turbine applies the boundary layer effect. The fluid is affected by the viscous force, and a thin boundary layer will be formed on the edge of the pipe wall or other objects. In the boundary layer, the flow velocity of the fixed surface is zero, and the farther away from the surface The greater the speed. Using this effect, a group of discs can be driven by the high-speed moving fluid to rotate. Tesla turbines can be up to 95 percent efficient, much higher than ordinary bladed turbines. Although the Tesla turbine has the advantage of high efficiency, due to the low torque of the Tesla turbine and its high sensitivity to mechanical friction, the existing Tesla turbine...

Problems solved by technology

However, such a structure is not a gas turbine in the true sense. Compared with traditional gas turbines, the efficiency is still low

At the same time, if the existing technology is directly improved and the combustion chamber is added, the high temperature in the combustion chamber will cause damage to the generator. Therefore, there is no real gas turbine using a Tesla turbine as a compressor and a turbine.
