In the present work, a numerical analysis has been presented to show the variations in flame structure, flame radiation, and formations of soot and NO in methane-air laminar nonpremixed flames with different dilutions of fuel. It is observed that the flame length reduces as the dilution of the fuel stream by increases while maintaining constant fuel jet velocity at the burner tip. However, the flame length remains almost unchanged with different blends of and if the burner loading (i.e., fuel flow value of fuel) is kept constant. Both soot and NO formations decrease monotonically when the fraction in the fuel is increased. The radiation from the flame also decreases when dilution of the fuel is increased, particularly, when the fuel jet velocity is maintained constant.
