Problems solved by technology

At present, when the fuel and air are mixed in the gas turbine, the swirler and the injection structure are buckled together, that is, the swirler and the fuel injection structure are two independent parts, which are designed and processed separately during manufacture. and then assembled together, which makes the processing high and the equipment more bulky

Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] In order to facilitate the understanding of the swirler assembly provided by the embodiment of the present invention, its application scene is firstly described, and the swirler assembly is specifically applied in a combustion chamber. The combustion chamber is specifically a combustion chamber in gas turbine equipment and other equipment that requires mixed combustion of fuel and combustion-supporting gas to generate energy. Wherein, the combustion-supporting gas may be oxygen, and the fuel may specifically be combustible substances such as hydrogen and methane. In application, the swirler assembly is assembled on the inlet of the flame tube in the combustion chamber, so that the combustion-supporting gas and fuel that are about to enter the flame tube ar...

Abstract

The invention provides a swirler assembly, a combustion chamber and a gas turbine. The swirler assembly comprises a swirler, and the swirler comprises a first support part and a second support part opposite to each other, and a plurality of swirler vanes arranged between the first support part and the second support part in a clamped mode. The swirler assembly further comprises a plurality of fuelinjection vanes arranged between the first support part and the second support part in a clamping mode. Each swirler vane and the first support part are of an integral structure, each fuel injectionvane and the first support part are of an integral structure, and at least one fuel injection hole is formed in each fuel injection vane. The swirler assembly further comprises a fuel inlet communicated with each of the at least one fuel injection hole. In the above solution, through arranging the fuel injection vanes and the first support part on the swirler as an integral structure without the need of buckling the swirler and a fuel injection structure together, the fuel injection vanes are convenient to arrange, processing and assembly difficulties are simplified, and the weight is reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a swirler assembly, a combustion chamber and a gas turbine. Background technique [0002] Micro gas turbines have the characteristics of compact structure, light weight, and low maintenance costs, and can be widely used in the field of distributed power generation. The combustion chamber is one of the three major components of the micro gas turbine, and the overall performance of the combustion chamber directly affects the overall performance of the micro gas turbine. At present, government departments have increasingly stringent requirements on the discharge of pollutants generated by combustion. In order to reduce the emission of pollutants in the combustion chamber, the mainstream design concept in the world is premixed combustion, and the combustion temperature is controlled at 1600K-1900K. Premixed combustion is to mix fuel and air before combustion, and then the mixture e...
