Abstract:
1. A fuel element adapted for use with a candle assembly having a wick retained by a wick holder including a wick retainer and an upwardly extending heat fin disposed on each of two opposite lateral sides of the wick retainer, the fuel element comprising: a body of substantially solid fuel material defining an empty duct extending between an upper surface of the body and an empty cavity larger than the duct defined by a lower surface of the body, wherein the duct is adapted to receive the wick, the wick retainer, and the heat fins therethrough in an assembled condition; wherein the duct comprises a slot having a first width in a width dimension, a first length in a length dimension at the upper surface greater than the width, and a second length at the cavity, and wherein the first length is less than a largest lateral dimension between opposite edges of the heat fins and the second length is larger than the largest lateral dimension between the opposite edges of the heat fins; and wherein the first width ensures that melted fuel material from the body entering the duct will contact the wick in the assembled condition and wherein the length dimension continuously tapers from the upper surface to the cavity.
