ANSYS-Fluent was applied to simulate diffusion combustion flame in a two-dimensional (2D) industrial burner to determine the contours of the mass fraction of gas emissions, ve-locity, and combustion temperature. The effects of the boundary conditions, including momentum, thermal, and species (inlet air, inlet fuel, and outlet pressure) on combustion temperature and mass fraction (gas emissions), were analyzed in the designed burner. The present study focused on using and analyzing the volumetric reaction and the turbu-lence-chemistry interaction of the eddy dissipation model for the diffusion flame model of kerosene in the field of combustion. The simulation used the discrete ordinate model and p1 for radiation and the k-e model for turbulence with enhanced wall treatment. Fuel con-sumption reduction was the main positive consequence of using this burner. Based on the results, the magnitude velocities of air and fuel, inlet temperature, and mass fraction of oxygen and inert gas can influence the parameters of flame temperature and gas emissions in the industrial burner. The inlet temperature provided a similar trend for the selected ra-dial positions. Adding the inlet temperature to the combustion chamber can increase flame temperature distributions. By varying the inlet temperature and oxygen mass fraction, the flame configurations on temperature, CO2, and H2O form a symmetry flame. The tempera-ture distribution resulted in the centerline being hotter than other radial positions for all the inlet temperatures. The emissions of CO2 and H2O generally rise with the addition of the oxygen mass fraction.
