When the quantity of petroleum fuel resources is decreasing, substitutes for conventional petroleum fuel are needed. Therefore, there are various species of renewable fuel such as residual fuel of emission from the fuel cell and biomass gas. Now, there are assignments that the low-calorie fuel and the biomass gas are utilized for renewable energy. Various species of renewable fuel such as biomass gas which includes mainly methane are widely used for substitute fuel. Holding the flame is an important pole in the burning technique for taking out the energy effectively. It is found that the parameters for holding the diffusion flame are fuel velocity, co-flowing velocity, nozzle diameter (curvature), type of burner nozzle and condense of the fuel. The objective of the present study is to get further understanding of lifting/blow-off in the radial horizontal jet diffusion flame. The radial horizontal jet diffusion flame is formed by using slit type of nozzle. The simulation of the numerical computation by using PHOENICS is compared with experimental data for the flame structure on which flame holding of the horizontal jet diffusion flame depend. It is to make clear of the behaviors and the stability limit of the horizontal jet radial diffusion flame.
