PURPOSE:To realize high load combustion by a method wherein a recess portion having a tip end section which the tip is bent sharply at the both side thereof, is formed along the longitudinal direction of a flame port portion and the many flame ports of a slit type or round hole type are arranged. CONSTITUTION:Fuel, injected from a nozzle toward the primary air port 1 at high speed, absorbs the primary air by ejector effect, becomes mixture at a mixing pipe 2 while it is adjusted to the uniform flow velocity at an equalization portion 3 and is supplied to the flame port section 4. Premixture is injected from a flame port 7 along an inner wall due to the sharp bending of the tip end section 6, and a fish tail flame (a) is formed. The flame is separated to large two parts due to the two tip ends 6 and the fish tail flame is formed, therefore, the secondary air is supplied enough, even when the amount of the combustion is increased, the flame length does not become large. According to this method, the high load combustion may be achieved.
