PURPOSE:To facilitate to fit an inner pipe to a wick guide cylinder, and to prevent kerosene steam from getting into the guide cylinder, by fixing the inner pipe to a hole provided to the guide cylinder by providing swelled projections to both ends of an inner pipe, in order to pierce a manipulating shaft to move a wick elevating device through the guide cylinder, in a kerosene combustion apparatus. CONSTITUTION:The bottom of a tank 1 of the main body of a kerosene combustion apparatus is welded, and uprightly projected cylinder body 2 to guide a wick is provided to the top surface of a tank 1. A hole to pierce through a manipulating shaft to move a wick elevating device is previously provided to the cylinder body 2. The periphery of a hole is depressed to the inside in some degree, and an inner pipe 3 is installed into the hole. The swelled projections 4, of which diameters are larger than that of an inner pipe 3 are formed in the positions near the both ends of an inner pipe 3, in order to fix the inner pipe 3 to the inside of a cylinder body 2. With such an arrangement, fitting work of an inner pipe 3 to the cylinder 2 can be facilitated, and there is not a fear that kerosene steam will get into the guide cylinder, as a result, offensive odor will not be produced, and there is not a danger that abnormal combustion will occur during combustion. |
