A liquid fuel burning torch system maintains fuel within one or more torches by pumping fuel from a central reservoir to the torches via a plumbing system. The torches can be extinguished by reversing the flow of the fuel in the plumbing system, for example by reversing a pumping direction of the pump, switching pumps, or actuating flow reversal valves. The torches can include remotely controlled torch igniting mechanisms, wireless access for remote torch monitoring and/or control, and/or heat sensors for determining whether the torch is burning. The torches can include fuel overfill prevention (FOP) valves. A flow of fuel through the FOP valves can be directed so as to avoid impinging on plugs of the FOP valves. The FOP valves can include check valves that allow fuel to be drained from the torches even when the FOP valves are closed.

A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.

A system and method for refilling a liquid fuel candle includes a refillable container and a refilling station with a reservoir of liquid fuel and a designated region for receiving the refillable container. A user control activates a pump causing fuel to flow from the reservoir and into the container until a predetermined fill level is reached, at which time the pump is deactivated. In one configuration the bottom of the container includes a port that cooperates with a post on the refilling station causing the candle to fill from the bottom up. The refilling station may further include an input for receiving a colorant or a scent that is added to the fuel as it flows from the reservoir to the container. The refilling station may include a plurality of designated regions for receiving a plurality of containers to be refilled, including simultaneous refilling.
