Among the efforts to reduce carbon footprint, testing low-carbon fuel blends is an important one. For this purpose, burning ammonia (NH3) gas in a mixture with different fuels stands out. In this study, analyses of methane/ammonia mixtures under oxy-fuel combustion conditions were carried out in a model gas turbine burner. During the analyses, the thermal power was kept constant at 3 kW, while the equivalence ratio was set at 0.7 and the swirl number at 1. The air inlet temperature was kept constant at 300 K and the gauge pressure at 1 Bar. In addition, a premixed and swirl-supported burner was used as the burner. Laminar and turbulent flame speeds, Damkohler number, flame temperature and pollutant emission values were determined in the study. The results showed that the addition of ammonia increased the turbulence intensity of the flame. While the addition of ammonia reduced the flame temperature, it also reduced CO emissions. In addition, the increase in the NH3 ratio in the fuel mixture at high O2 ratios also increased NOX emissions. Another result of the study is that the flame length and thickness decrease as the ammonia addition rate in the methane/ammonia mixture increases. On the other hand, due to the increased flame speed at high O2 ratios, an increase in flame thickness and length was observed under the conditions of 10% NH3 addition.
