As a result of the climate crisis caused by energy efficiency and post-combustion emissions, the importance of studies on alternative fuels and combustion processes has also increased. In this study, the effect of dilution effect on flame temperature, brightness and flue gas emission values was investigated by adding CO2 gas to a pure methane flame at constant thermal power in a swirl supported and premixed burner. The thermal power of the burner was determined as 5 kW and the equivalence ratio was fixed at 0.9. While the burner outlet temperature of the pure methane flame was 1058 K under the specified conditions, it decreased to 1032 K with the addition of 30% CO2. With the decrease in the combustion temperature, the NOx value measured at 17 ppm in the pure methane flame was reduced to 13 ppm as a result of 30% CO2 dilution. On the other hand, as a result of the addition of CO2 under the same conditions, CO emissions increased from 303 ppm to 1687 ppm.
