Ammonia is a potential CO2 zero emission energy substitute,therefore in-depth research on its combustioncharacteristics is of great significance for optimizing the combustion process and reducing environ-mental pollution.This study used Chemkin software to simulate and explore the combustion characteristics of NH3/CH4 gas mixtures.By comparing the heating value,flame propagation speed,and nitrogen oxide emission content during the combustion process of NH3/CH4 with different mixing ratios.The simulation results show that under different mixing ratios,the combustion rate of NH3/CH4 is the fastest under stoichiometry,but it al-so produces more nitrogen oxides.In practical applications,multiple factors should be comprehensively consid-ered to achieve the highest combustion efficiency and the lowest environmental pollution.
