PURPOSE:To prevent the generation of foul odor by eliminating imperfect burning at the ignition and extinction time by using an ignition means in such a manner that at the ignition time the gasification amount of kerosene is gradually increased after the ignition and the ignition means is operated after the gasification amount of kerosene has been gradually decreased at the extinction time. CONSTITUTION:Kerosene in a fuel tank 2 is mixed with air supplied from an air pump 5 and gasified by a gasification device 3 and this gasified kerosene is supplied to a combustion dish 1 through a fuel supply path 7. An ignition heater 8 is operated by the instruction from a control circuit 10 via an ignition circuit 9 and foul odor due to imperfect burning can be held down to the lowest limit by increasing gradually the gasification amount after the ignition. At the extinction time the gasification amount is gradually decreased by the gasification device 3 and the ignition heater 8 is operated by the instruction from the control circuit 10 and therefore, residual gas is perfectly burned and foul odor is eliminated. |
