ABSTRACT:
An apparatus for producing a sustained flame, comprising: a first reservoir for containing a first flame-fueling liquid; a second reservoir for containing a second flame-fueling liquid; a first wick having a first end disposed within the first reservoir and a second, flame-bearing end generally located above the first end; a second wick disposed substantially adjacent to the first wick, having a first end disposed within the second reservoir and a second, flame-bearing end above the first end; and at least one air channel disposed to supply oxygen to each wick, where a first end of the at least one air channel is generally located near the flame-bearing end of each wick; whereby, when the first and second flame-fueling liquids are supplied to the first and second reservoirs, the first and second flame-fueling liquids are communicated up the first and second wicks to fuel flames emanating from the flame-bearing ends of the first and second wicks.A method for controlling a flame comprising: controlling a first flow of air to a first flame; controlling a second flow of air to a second flame; wherein the first flame and the second flame are concentrically disposed.
