ABSTRACT:
A gasified liquid fuel combustion apparatus which includes a gasifier in which liquid fuel is heated and gasified and delivered to a burner for combustion. A nozzle provided at the outlet of the gasifier is opened and closed by a valve needle operated by a solenoid. A solenoid control circuit includes first and second rectifying circuits between a power supply and the solenoid. A normally closed switch which is opened by a timer circuit is between the power supply and the first rectifying circuit, and a voltage reducing transformer is between the power supply and the second rectifying circuit. The first and second rectifying circuits are connected to a common output line so that a high DC voltage is supplied to the solenoid when the normally closed switch is closed and a low DC voltage is supplied to the solenoid when the normally closed switch is open.
