Abstract

Abstract: A new syngas combustion chamber of micro gas turbine is designed. The basic geometric dimensions of the combustion chamber, the location and area of the secondary air and the mixing cooling hole, as well as the structure of the swirl burner, are determined based on the results of the thermal calculation and related standards. Additionally, the performance of the designed combustion chamber, such as the cold and hot flow fields, the combustion stability and efficiency and the pressure losses, is studied with the computation fluid dynamics (CFD） software. Numerical calculation results show that the flow field of the designed combustion chamber is reasonable and the combustion is stable with high efficiency and low pressure losses. All these indicate that the design requirements are satisfied.

Key words: micro gas turbine, combustion chamber, hydrogen-rich syngas, numerical calculation
