In the present study, blowoff characteristics of methane-air edge flame are investigated by using the original burner. The burner can form edge flame as a hole in both stagnation flow and wall jet of an axisymmetric impinging jet. Comparisons of edge flames' shapes, blowoff processes and positions in two flow fields were performed. As the results, it is found that there are differences for edge flames' blowoff process and radial location at separation. In the stagnation flow, the separation of edge flame occurs at upward of the front edge of the porous plate for fuel ejection. On the other hand, in the wall jet, the edge flame shows separation when the edge flame is located at downward of the front edge of the porous plate. It is supposed to be that determinant factor for radial location of edge flame is important for determining edge flame's blowoff process.
