Ways of improving burners of two-staged combustion chambers

Abstract

This article contains materials about defect of two-stage combustion chamber gas turbine engine occurring by high temperatures. The design of basic burner with blade swirler is shown. Improvement of burner by using of the minimum of design changes is required. Ways by absence overheating of elements homogeneous burners combustion chambers is developed. Six variants of burners were selected for their studying. They were made by machining bush of basic burner. This machining bush consists of increasing diameter of inner center hole. It is having variant complete deleting bush and his changing on groove nozzle. Data of experimental works to determine capacity eight types of burners as function of air pressure and formatting field of pressure on edge of burner is presented. The research result of two types burner with groove nozzle for search new ways to solve task of increasing reliability burners is shown. Optimal method tweaking burners for absence overheating swirler was selected.
