Research on the Thermo-Kinetics Mechanism of CH4/DME High Pressure Premixed Combustion in Air/CO2 Atmosphere

Abstract:
Through the analysis of fuel composition and oxidant atmosphere, the premixed combustion characteristics of gas turbine are studied, and the application of binary fuel mixed with DME and CH4 in power system is explored. This paper research on the problems of CH4/DME in premixed combustion of gas turbine, including: the calculation of experimental data mostly focuses on the combustion stability, flame characteristics and pollutant emission under atmospheric pressure. Through CH4/DME premixed Air/CO2 high pressure combustion, the experiment of thermochemistry and reaction kinetics mechanism is established, and the numerical simulation research is established to deeply explore the combustion performance, combustion emission and their balance relationship of premixed combustion. It provides a further theoretical basis for the high-pressure combustion of non-standard fuels in industry.
