The experimental investigation on blowout characteristics have been made for a swirl-stabilized premixed oxyfuel flame at different swirl-conditions. Being compared to a conventional air-fuel flame, a CH₄/O₂/CO₂ oxyfuel flame is expected to easily blowout due to its slower chemical kinetics, mainly induced by high CO₂ concentration in the reactant gases. Experimental results, from this study, confirm the above theoretical expectation; blowout of oxyfuel flames occurred at higher flame temperature condition, being compared with the air-fuel flame results. From the experimental results, at different swirl condition, it can also be reveled that the swirl intensity has strong effect on the blowout characteristics; at higher swirl number, strong recirculation is introduced, consequently flame easily becomes unstable due to higher CO₂ concentration.
The results has also been compared with the mathematical modeling data; the data are obtained from literature. As a result, the mathematical model can predicts the blowout characteristics of the oxyfuel flame with acceptable error range; however further consideration should be made to improve predictability.
