なく炎を有効に利用出来る。The present invention utilizes a fuel gas injection energy to increase the speed of the primary mixed gas at a mixing ratio smaller than that of the ordinary air, thereby making the combustion plate having a slope at the opening of the injector tube. Spray the flame so that it hits the tip of. The injected mixed gas hits the combustion plate to flatten the shape of the mixed gas to increase the contact area with the secondary air, and ignite the secondary air in a state in which the secondary air is taken in more than the entire upper and lower portions of the flame. Since the flame hits the combustion plate, the flame rises rapidly and ignites well, and unburned gas is not generated. Therefore, generation of carbon monoxide can be prevented, and at the same time, extinguishing can be prevented. The primary mixed gas has a small amount of air to increase the speed, and the secondary mixing mixes the air with the gas having a high speed in the secondary mixing, so that the flame length is short and a high temperature can be generated, so that the calorie is high. When incorporated in a kitchen, the flame concentrates on the combustion plate and the flame can be used effectively without heating unnecessary parts of the kitchen.
