Prediction of a Diffusion Flame Characteristics with the Influence of Repulsive Electromagnetic Fields

This paper describes an experimental study of influence of magnetic field on diffusion flame in the counter burner. Diffusion flames for different LPG gas flow rates propagating in counter burner of a different magnetic field intensities 1000 to 5000 gauss have been experimentally investigated. An influence of the changing fuel gas flow rate, magnetic force on the flame structure, combustion velocity and flame temperature has been determined. In the present work, the diffusion flame recording images was used to analyze the effect of changing magnetic field intensity on the flame disc diameter. Significant results were obtained in the area of counter flame. Flame disc diameter in the counter burner depend basically on the velocity of fuel and air. Flame diameters are almost the same for top and bottom flame disc and decreased with increasing the magnetic field intensity. At the fuel flow rate values (Re = 22, 31), the values of combustion velocity were increased with increasing magnetic intensity, and this behavior due to probably caused by effect magnetic force on oxygen zone.
