PURPOSE:To hold the temperature of a vaporization part at a proper value when temperature is low and to reduce the temperature of the heat recovery part of the vaporization, in a burner to vaporize liquid fuel for combustion. CONSTITUTION:A burner is formed such that a combustion air feed route 20 is arranged to the periphery of a burner part 14 and after the combustion heat of the burner part 14 is recovered to preheat combustion air, the air is fed in a vaporization part 11. Thus, the combustion air is fed to a vaporization part 11 after it is preheated by the combustion heat of the burner part 14, and cooling by the combustion air and emission of heat to the periphery of the vaporization part are reduced. This constitution facilitates holding of the temperature of the vaporization part at a proper value regardless of the change of an outside air temperature, and reduces the temperature of the heat recovery part of the vaporization part. |
