Fuel gas turbine

Abstract

The invention discloses a fuel gas turbine. The fuel gas turbine comprises a power system and a pressurizing system, wherein the power system comprises a main machine shell, the main machine shell is coaxially provided with an impeller, the impeller is provided with a power output shaft, and the edge of the impeller is provided with blades, the periphery of the main machine shell is provided with an annular sealing region, the blades are arranged in the annular sealing region, and the annular sealing region is at least provided with a work-doing region for causing fuel gas to push the blades to work; one side of the annular sealing region is a non-work-doing region which is provided with a waste gas outlet, and the outer edge of the work-doing region is provided with a cylinder end for generating the fuel gas; and the pressurizing system is used for providing compressed gas for the cylinder end, and the pressurizing system comprises a turbocharger, a pressurizing machine and a startup pressurizing device. The fuel gas turbine provided by the invention has the advantages that the structure is simple, the maintenance is convenient, the power property is better, and the heat utilization ratio is high.

Description

technical field [0001] The invention relates to a gas turbine. [0002] Background technique [0003] Most of the traditional internal combustion engines are piston-type, and the piston is driven to do work by igniting the mixture of compressed air and fuel. Due to the discontinuity of its work (four strokes do work once), there is a problem that vibration will occur. In addition, the self-ignition air-breathing type The engine is destined to burn insufficiently. If the compressed air is used to make it burn fully, it will generate a high temperature, which will put forward higher requirements for the cylinder block, piston and lubrication system, and their requirements for fuel are also relatively simple. Different machines only Suitable fuel can be used. At present, gas turbines use gas to pass through the turbine, so that the turbine rotates to drive the rotor to rotate and work. Its characteristic is that the fuel volume must be large enough to provide sufficient power...

[0003] Most of the traditional internal combustion engines are piston-type, and the piston is driven to do work by igniting the mixture of compressed air and fuel. Due to the discontinuity of its work (four strokes do work once), there is a problem that vibration will occur. In addition, the self-ignition air-breathing type The engine is destined to burn insufficiently. If the compressed air is used to make it burn fully, it will generate a high temperature, which will put forward higher requirements for the cylinder block, piston and lubrication system, and their requirements for fuel are also relatively simple. Different machines only Ability to use fuel suitable for it

However, the structure of the device provided by this patent is relatively complicated, and high-temperature gas is used as the power source, which has high requirements for bearings and sealing devices
