PURPOSE:To form opposing flames at a right angle with a flat surface to a flame port and to form stable flames without change by a method wherein a side wall provided on the flame port is opposed by a fixed distance through an air cap and the side wall is projected from the flame port part. CONSTITUTION:Flame ports 8, 9 are opposed with an air gas 16 between them are premixing gas is ejected from the opposed flame, ports to collide in the air gap. The premixing gas ejected from the opposed flame ports 8, 9 to a combustion chamber is ignited and the opposing flames 17 is formed, at this time, the stable opposing flames are formed in case the premixing gas 12, 13 are laminar flow. A stagnation point 20 between two flame surfaces of the opposing flame is formed, flow speed at the stagnation point is zero in ideal, the flow speed is small in this neighboring. The stagnation thereof may be contributed to the stable opposing flame 17.
