Embodiment Construction
[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered below.
[0029] refer to figure 2 , the preferred embodiment of the present invention provides a gas turbine fuel pipeline structure, including: a fuel manifold extending along the fuel delivery direction, and a fuel nozzle 10 for spraying and atomizing the fuel delivered by the fuel manifold outwards. The fuel inlet end of the fuel main pipe is communicated with the pipeline for supplying fuel. The fuel nozzles 10 are arranged at intervals along the extending direction of the fuel manifold, and each fuel nozzle 10 is integrally arranged with the fuel manifold to deliver fuel as part of the fuel manifold, while spraying and atomizing the delivered fuel portion outward.
[0030] Compared with the prior art structure in which the fuel manifold and the fuel nozzle...

The invention discloses a fuel oil main pipe extending in the fuel oil conveying direction and a fuel oil nozzle used for spraying and atomizing fuel oil conveyed by the fuel oil main pipe outwards. The oil inlet end of the fuel oil main pipe is communicated with a pipeline used for supplying fuel oil. The fuel nozzles are sequentially arranged at intervals in the extending direction of the fuel main pipe, and all the fuel nozzles and the fuel main pipe are integrally arranged so as to serve as part of the fuel main pipe to convey fuel, and meanwhile the conveyed fuel is sprayed outwards to be atomized. According to the integrated structure of the fuel oil main pipe and the fuel oil nozzles, metal branch pipe structures are reduced, meanwhile, the number of outer sleeve nuts is reduced, and therefore the structure of a fuel oil pipeline is greatly simplified, the weight of the fuel oil pipeline structure is reduced, and the manufacturing cost is effectively reduced; and the risk of oil leakage at the joint of the fuel header pipe and the fuel nozzle is effectively reduced, the number of pipeline joints is reduced, and the working reliability of the fuel pipeline is greatly improved.
Description
technical field [0001] The present invention relates to the technical field of gas turbines, and in particular, to a fuel pipeline structure of a gas turbine. Background technique [0002] The fuel manifold is one of the key components of the gas turbine fuel system. Functionally, the fuel manifold mainly plays the role of transporting fuel. The fuel is transported to the fuel nozzles through the fuel manifold, and then supplies fuel to the combustion chamber; in the working environment, the fuel manifold Working in a high temperature area for a long time, the temperature and pressure of the fuel transmitted inside are high, so there are higher requirements for the sealing and reliability of the fuel manifold. The function of the fuel nozzle is mainly to atomize the fuel delivered by the fuel manifold. . [0003] Common fuel mains are divided into non-metallic hoses and metal hard pipes. At present, some gas turbines use the structural form of metal hard pipes. For fuel ma...
