PURPOSE:To prevent primary air introducing openings from being clogged due to adhesion of tar thereby securing stabilized combustion, by securing a thermal insulator to a vaporizing chamber front plate through a heat insulating wall that covers the front on the atmosphere side of the vaporizing chamber, and supporting a jet nozzle at the center section of the heat insulating wall. CONSTITUTION:The burning in a combustion chamber 9 heats a vaporizing chamber cylinder 5, and the heat of the cylinder will be transmitted to the vaporizing chamber front plate 14 through a vaporizing chamber patch 12 and a packing 13 and then to the heat insulating wall 16. However, since there is the thermal insulator 15 interposed between the front plate 14 and the heat insulating wall 16, the heat would not be transmitted. Therefore if the heat insulating wall 16 is cooled by the atmosphere, the vaporizing chamber front plate 14 would not be cooled. Accordingly, tar would not adhere to the inner surface of the vaporizing chamber front plate 14, and the air openings 18 would not be clogged. As a result, the combustion in the vaporizing chamber 6 can be stabilized at all times. |
