This work is constituted by an experimental study contemplating the testing of diffusion flames that have been extinguished with a perpendicular jet of air. The influence on flame extinction has been analyzed considering the variation of four types of parameters: (i) propane and methane fuel, (ii) fuel-air velocity ratio, (iii) burner nozzle diameter, and, finally, (iv) axial distance between the burner outlet and the air jet location. This work has aimed to address the problem experimentally by analyzing image visualization techniques to determine the type of air-jet that has been injected and the type of extinction that has been produced by varying the aforementioned geometrical and fluid parameters.
