PURPOSE: To cause efficient combustion and to improve a combustion rate by suppressing the heat radiation quantity of a catalyst and increasing the contact area of gaseous fuel with the catalyst at the time of utilizing the heat obtd. by bringing the liquefied gaseous fuel into catalyst combustion for an iron.
CONSTITUTION: The liquefied gaseous fuel is evaporated from a fuel tank 3 disposed in an iron body 1 and is ejected from a nozzle 4. The gaseous mixture with air is supplied to a combustion chamber 6. Fins are projected to the inside surface side of the combustion chamber 6 and the catalyst 8 is arranged in the combustion chamber 6 to cover the fins. A base 10 is heated by the generated combustion heat generated by the combustion using the catalyst 8. At this time, a space part is formed between the catalyst 8 and the fins 7, by which the radiation quantity of the combustion heat from the catalyst 8 to the fins 7 is suppressed and the high catalyst temp. is maintained.
