PURPOSE:To prevent the production of unburnt gas and to prevent an offensive ordor by a method wherein an oxidation catalyst is placed in a cleanrance of the combustion cylinder. CONSTITUTION:A small hole 2 for providing an instanteneous fire distinguishing is prepared at the side wall of the core storing cylinder 1. In the core storing cylinder 1 is stored a combustion core 3 being closely contacted to the side wall of the cylinder, and the combustion core 3 is moved up and down with a core lifting knob 4 so as to adjust a thermal power. In case of an automatic instanteneous fire distinguishing, combined with a sensing unit, the small hole 2 of the core storing cylinder 1 is located higher than the upper end of the combustion core 3. Further, an oxidation catalyst 11 is placed in the clearance 10 of the combustion cylinder formed by the chimney inner flame cylinder 8 and the outer flame cylinder 9. Then, the gasified petroleum is completely oxidised in case of fire distinguishing and accordingly the production of an offensive odor may be prevented. |
