Abstract
The invention is directed to an apparatus for use in producing a simulated flame/fire effect using steam or theatrical smoke. In one embodiment, the apparatus includes an first chamber for receiving steam or theatrical smoke, an annular second chamber that surrounds the first chamber and defines an annular closed-loop slot through which a closed-loop sheet of steam or theatrical smoke exits, a passageway for conveying smoke from the first chamber to the annular second chamber, a lighting structure for projecting light onto the steam or theatrical smoke exiting the annular slot, and an air modulator for modulating the position of the steam or theatrical smoke exiting the slot.
