  • For a kind of gas burner, the appropriate size of the combustion chamber is selected to match, and then a complete calculation area was formed. Natural gas fuel and combustion air were injected into the combustion chamber through the gas burner to realize the complete combustion process. By simplifying the gas burner to complete geometric modeling, heat flow and combustion analysis software were used for numerical simulation of the calculation area, and the Realizable k-ε turbulence model, ED combustion model, DO radiation model and thermal NOx generation model were selected to explore the influence of excess air coefficient α on the combustion process of the gas burner. The cloud image and distribution of temperature field and NOx concentration field were obtained and analyzed. When the excess air coefficient α = 1.1, the NOx concentration reached the maximum. The research results can provide reference for relevant research experiments and design of low NOx burners.
