A candle having a body of a meltable fuel and a planar wick. When lit, the candle provides a unique flame formation, usable in a variety of decorative applications. The wick can be configured to evenly deplete the meltable fuel, while allowing for candles having relatively large and unique body configurations. The body of candle and/or the wick may include scented oil to promote the release of fragrance upon heating. The wick preferably is formed of wood, thereby providing an acoustic contribution to ambiance and improved combustion that generates less soot than conventional cotton wick candles.

A candle stand includes a container and a bowl supported by an inner periphery of the container and having a hollow column formed on top of the bowl. The hollow column has multiple pawls each having a bend formed on a free end of the pawl and extending toward a central axis of the hollow column so as to clamp a wick. Multiple through holes are defined through a base of the bowl, wherein a space is defined between a bottom face of the container and the base of the bowl for receiving liquefied wax.

The invention relates to a porous burner with a housing, which has an inlet for a fuel-air mixture and an outlet for the exhaust gas mixture generated in the burner, where in flow-direction of the fuel-air mixture the housing contains an ignition space with an ignition device and adjacent to this space a porous burner medium. On the inlet side the ignition space is provided with a stabilizing element, which reduces the inlet cross-section and directs the flow of the fuel-air mixture essentially perpendicular to the inlet cross-section of the porous medium. The porous burner is provided with a device for controlling the mass flow of the fuel-air mixture, which serves to shift the combustion zone from the ignition space into the porous medium.

A flame-retardant wick holder for a candle is made of a material having a UL-94 vertical burn test rating of at least V-0, including polymers and ceramics. The wick holder supports a wick at the bottom of a candle. The wick holder material causes the flame on the wick to extinguish when it reaches the holder, thereby preventing flashover of the residual candle fuel at the end of the candle useful life. One version of the holder has a cylindrical sleeve fit over a wick clip holding the lower end of the wick. The cylindrical holder is well adapted for use in pillar-type candles.

A portable heat generating device in which fuel vapor and an oxygen supply (e.g. air) are directed through channels contained within a thin, flexible and compliant elastomeric sheet of material. Elongated catalytic heat elements, placed strategically within the channels, spontaneously interact with the fuel-air stream liberating heat energy. Means and methods are defined that permit flameless catalytic combustion to be uniformly extended over the length of each heat element, lowering power density but maintaining the overall power generated, permitting the use of many types of low temperature materials like plastics, polymers, and elastomers in the construction of the heater. The heat generation process is started by pumping an air stream into a reservoir containing a fuel source (e.g. methanol) thereby saturating the air stream with fuel vapor. The fuel vapor is mixed with a another stream of air to achieve a particular fuel/air ratio and directed into channels within the elastomeric sheet, reacting with the catalytic heat elements to produce flameless combustion. The warm exhaust gas is directed to a thermally controlled diverter valve. The valve senses the temperature of the liquid fuel supply and diverts some or all of the warm exhaust gas, as necessary, to heat the fuel and keep its temperature within a specified range. Exhaust by-products are passed into a miniature scrubber module adjacent to the fuel module. The scrubber absorbs any noxious components in the exhaust stream that may occur during start-up or rapid changes in operating condition.

Disclosed herein is a light emitting melody candle.
