Abstract: The present invention is directed to an improved combustion apparatus particularly adapted for use with fuels which are solid at ambient temperatures and readily meltable at temperatures exceeding ambient, an example of such fuel being paraffin. The apparatus includes a two-part float assembly adapted to float upon the molten surface of the fuel and includes a heat conductive bottom plate, the device being characterized by efficient heat transfer from the flame to the bottom plate, whereby it is assured that the fuel beneath the plate will be in a molten condition.

Abstract: The present invention is directed to a combustion apparatus particularly intended for use with fuels which are solid at normal ambient temperatures but are readily meltable at temperatures somewhat exceeding ambient, the fuels being combustible in their molten state. An example of a preferred form of fuel is paraffin.The apparatus preferably includes a two part plate assembly adapted to float upon molten fuel, the plate assembly being centrally apertured and provided with a wick extending through the aperture, the heat developed by combustion by the wick being transmitted through the conductive plate assembly to heat and thereby melt a supply of fuel directly below the assembly.
