<P>PROBLEM TO BE SOLVED: To provide a combustion device maintaining the temperature of a vaporizing cylinder at a vaporizable temperature. <P>SOLUTION: A partitioning cylinder 25 in a form of a bottomed cylinder, in which a bottomed cylindrical portion of a vaporizing cylinder 1 is to be disposed, is disposed between the vaporizing cylinder 1 and a burner casing 12 fixed to a burner mount base 9 in such a manner that the vaporizing cylinder 1 is disposed inside the casing and the opening of the cylinder is located below an aeration hole 10 of the burner mount base 9. Since the partitioning cylinder 25 includes a damper 31 that opens and closes a secondary air outer flow passage 26 formed by the inner face of the burner casing 12 and the outer face of the partitioning cylinder 25, and a secondary air inner flow passage 27 formed by the outer face of the vaporizing cylinder 1 and the inner face of the partitioning cylinder 25, the vaporizing cylinder 1 can be cooled without increasing secondary air and the temperature of the vaporizing cylinder 1 can be increased without energizing a sheath heater 2 of the vaporizing cylinder 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
