摘要：
The effect of hydrogen doping ratio on the flow and temperature fields in the combustor and the emission of the main pollutants (CO and NOx) for a constant excess air coefficient, a constant gas turbine power and different hydrogen doping ratios has been analyzed through numerical simulations for the application of natural gas blended hydrogen combustion technology in a 100 kW micro gas turbine. The combustion reaction principle used in the study is a simplified version of the GRI-Mech 3.0 mechanism, which includes 17 species and a total of 24 radical reactions. The simulation results show that the maximum temperature in the primary combustion zone of the combustor decreases as the hydrogen doping ratio gradually increases, the temperature distribution of the gas exiting the combustor becomes more uniform, and the gas gradually improves. The concentration and total emission of major pollutants gradually decrease.
