Multi-layer flow guide lining of combustion chamber of gas turbine

Abstract

The invention discloses a multi-layer flow guide lining of a combustion chamber of a gas turbine. The multi-layer flow guide lining comprises a flow guide lining outer body, wherein a connecting end cover is arranged on the outer surface of one end of the flow guide lining outer body, and a fuel nozzle is arranged on the outer surface of one end of the connecting end cover. According to the multi-layer flow guide lining of the combustion chamber of the gas turbine, when the lining is used, air can better enter a flame tube to be combusted, the combustion effect can be better when the lining isused, and waste caused by insufficient combustion of fuel can be avoided; when a heat conduction piece is used, the temperature generated in the flow guide lining outer body can be rapidly volatilized; when the lining is used, heat is conducted, so that the heat is volatilized through the heat conduction piece; and when a drainage piece is used, the air can be guided, the air can be more sufficient when the drainage piece is used, the air and the fuel can be mixed and combusted more rapidly, the working efficiency can be improved when the lining is used, and the selectivity is high when the lining is used.

Description

technical field [0001] The invention relates to the field of gas turbine equipment, in particular to a multilayer diversion bushing for a combustion chamber of a gas turbine. Background technique [0002] The gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at high speed, and converts the energy of the fuel into useful work. It is a rotating impeller heat engine. The working process of the gas turbine is that the compressor ) continuously inhales air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel and burns to become high-temperature gas, which then flows into the gas turbine to expand and do work, pushing the turbine impeller to drive the compressor The impeller rotates together; the working ability of the heated high-temperature gas is significantly improved, so when the gas turbine drives the compressor, there is s...

Problems solved by technology

[0003] However, there are certain inconveniences in the use of the existing diversion bushings. The existing diversion bushes cannot guide the air very well during use, and the flow direction of the air is prone to confusion during use. Moreover, the heat dissipation effect of the existing diversion bushing is relatively general during use, and it is easy to accelerate the aging speed during long-term use. The existing diversion bushing is not strong when used, and is prone to deformation and damage
