abstract = {In order to study the changes of combustion characteristics of domestic gas stoves after mixing natural gas with hydrogen, numerical simulation and thermal experiment research are carried out on the application of natural gas hydrogen-mixing combustion technology in household swirl gas stoves. First, the detailed mechanism GRI-Mech 3.0 is simplified. Through comparison and verification, the error between the simplified mechanism and the original mechanism is less than 1%. Secondly, using simplified mechanism for numerical simulation of pure methane gas stove, the numerical simulation and thermal experimental calculation results are compared and verified. It is found that the maximum error of the average temperature of the combustion zone does not exceed 12%, which confirms the feasibility of the simulation. Finally, a numerical simulation study of methane hydrogen mixing conditions is carried out. The calculation results show that the primary air coefficient of domestic gas stoves gradually increases with the increase of the hydrogen mixing ratio, which has a great influence on the combustion characteristics. After adding 15% of the volume of hydrogen, CO emissions are reduced by about 9%; and the temperature remains basically stable, which confirms the effectiveness of methane hydrogenation technology. The research results have reference value for the popularization and application of natural gas mixed with hydrogen in the combustion of gas stoves.}
