Description
Technical Field
The invention relates to the field of combustion of gas turbines, in particular to a special-shaped mixing hole mechanism and method for a combustor flame tube for adjusting mixing air quantity.
Background
The development of modern gas turbines towards high temperature rises has led to increasingly high outlet temperatures of the combustion chamber, i.e. the inlet temperature of the turbine is increasing. The outlet temperature is one of important performance indexes of the combustion chamber, and directly influences the service life and the reliability of the first-stage turbine guide vanes and the working vanes, so that the regulation and control of a high-quality outlet temperature field becomes a research focus and a difficulty of the combustion chamber of the current gas turbine. After the combustion and air cooling requirements are met, the remaining air and the combustion products are blended in the blending zone to provide an exit gas stream that can be taken up by the turbine. The air entering the combustion chamber from the mixing hole jet flow plays an important role in regulating the temperature distribution of the outlet of the combustion chamber. If the mixing area is not designed reasonably, the nonuniformity of the outlet temperature is increased, local hot spots are generated, the turbine efficiency is reduced, the heat load of the turbine movable blades is increased, the turbine blades are heated unevenly, and the blade cascade is locally overheated or even ablated.
Different working conditions have different requirements on the blending gas amount, and in order to obtain good outlet temperature distribution, higher blending gas amount is generally required under the condition of high oil-gas ratio and large working conditions, and higher blending gas amount is generally not required under the condition of low oil-gas ratio and small working conditions. After the structure of the mixing section is determined, the gas distribution of each part of the combustion chamber is certain under different working conditions, and the depth of the mixing jet flow is relatively kept unchanged. When the outlet temperature distribution of the combustion chamber is not uniform and unreasonable under a certain working condition, the mixing section structure is further optimized for debugging the quality of the outlet temperature field, and a large amount of time, financial resources and material resources are consumed.
