PURPOSE:To flame up vaporizing combustion flame in a stable condition from the beginning of the combustion, by warming a blast shell and a combustion shell with a part of generated combustion heat. CONSTITUTION:The fuel fed to the surface of a fuel diffusion unit 23 is turned into vaporized gas rapidly while the fuel is spread in a thin film form along a vaporizing shell 11 inside, and simultaneously during the flowing, the fuel is mixed with air for combustion to be perfect vaporized gas to be pressed into a gas chamber 5. The pressed-in gas is jetted through a slot 4 for gas jet created on a combustion board 3 and is flamed by combustion flame, and whole vaporizing shell 11 is heated by flaming the vaporizing combustion flame. Therefore, after the vaporizing combustion flame is generated, vaporized gas is continuously generated as the vaporizing shell 11 is intensively heated, and the vaporizing combustion with blue flame can be continued for a long time.
