PURPOSE:To enable a stable vaporization combustion to be continued even in case of a substantial combustion or a slight combustion by a method wherein a circulating action of mixture gas is forcedly restricted in the midway of its transmittance and the mixture gas is injected from each of the gas passage and the gas injection passage under its equal volume and correctly and ignited. CONSTITUTION:A plurality of mixture gas flow prevention means 24 are radially spaced apart relation in the midway of the gas passage 4 to partition off the midway and to form a plurality of linear gas passages 25. Therefore, the mixture gas forcedly entered into the gas passage 4 from the vaporization condition is restricted when it passes through circulation preventing means 24, and passes in the linear gas passage 25, thereafter an equal volume of gas is injected continuously under an annular form from the discharging part of the gas passage 4 in a forward direction. In turn, the circulating action of the mixture gas is forcedly restricted by the circulation preventing means 24, so that the annular combustion flame continuously injected from the gas injection passage 15 and ignited is also injected forwardly while being kept substantially in a linear line condition, resulting in that an occurrence of rich and lean combustion flames and a partial red combustion loss accident at the outer combustion cylinder 1 and the inner combustion cylinder 3 can be prevented. |
