ABSTRACT:
The liquid fuel burning apparatus includes a fuel tank, a burning unit for burning the fuel, an electromagnetic pump for sucking the fuel from the tank, a feeding pipe for feeding the sucked fuel to the burning unit, and a control unit for controlling the electromagnetic pump. The electromagnetic pump has a plunger which is reciprocated by a plunger solenoid to suck the fuel in the fuel tank and discharge the sucked fuel therefrom in the associative motion of a suction and a discharge valves incorporated therein. The control unit opens the valves for a predetermined time when the fuel supply is stopped. Thus, fuel remained at an end of the feeding pipe is collected from so that the unburnt gas or strange smell which would be generated when the unnecessary liquid fuel is supplied to the burning means can be restricted.
