PURPOSE:To eliminate the generation of unvaporized fuel and accumulation of unburnt gas by a method wherein oil fuel is jetted uniformly over the inner peripheral wall of a vaporization chamber so that the vaporizing capacity of the fuel and heating area by vaporization combustion flame are increased. CONSTITUTION:A vaporizer 1 having an air inlet 2 at one end and the vaporization chamber 3 inside is connected at the other end to a gas chamber body 4 which includes a gas chamber 5 inside and the side surfaces of which are constituted by combustion boards 6a and 6b from which a part of the vaporization combustion flame is directed toward the vaporizer 1. In the vaporizer 1, an oil fuel injection nozzle is arranged on the air inlet side. This structure makes it easy to enlarge the burning area of the vaporization combustion flame and thus constitute an effective heat source. With the vaporization of the oil fuel over the inner peripheral wall of the vaporizer 1, the vaporizing capacity can be increased and also a large volume of gas mixture can be generated easily. |
