Dilution is an effective process in reducing NO X emission, since diluents cause an increase in the mass flow of the fuel, and consequently the temperature in the combustion chamber and NO X emission decreases. We measured NO X emission and temperature for a wide range of dilution and equivalence ratios. The results show that nitrogen dilution is more effective than argon dilution in reducing NO X emission. In addition, both dilutions caused the yellow color of the non-premixed flame to turn blue, which indicates more complete combustion and better mixing of fuel and oxidant.
