PURPOSE:To improve ignitability of a burner by exposing to outside a part of a heater sunk into vaporization cylinder and bringing the exposed part into contact with a burnerhead. CONSTITUTION:Fuel that is sent form a supply fuel oil device 6 is jetted out into a vaporization cylinder 1 from a nozzle 3 through an oil pipe 5, and the air for combustion that is sent from a blower 8 is jetted out into a vaporization cylinder 1 from a throat through an air hose 7. Because a part of a sheath heater 2 which is sunk in the vaporization cylinder 1 is exposed to outside and is in contact with the burnerhead, the sheath heater 2 heats the vaporization cylinder 1 as well as the burnerhead to a high temperature as soon as the sheath heater is energized by conduction at the time of ignition. Consequently the fuel that is jetted out from the nozzle 3 and the throat 4 and the air for combustion are carbureted and mixed and go through the burnerhead 9 and are jetted out from side flame holes. With the arrangement ignition is made smoothly and it is possible to prevent offensive odor and white smoke generation due to the generation of unburned gas.
