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.

Abstract: The invention is directed to special effect device that is used to produce a simulated flame that has the shape and, if desired, the color characteristics of an actual flame. The device is particularly adapted to applications in which individuals may be in close proximity to the device. In this regard, the device produces little noise that would indicate to such an individual that the simulated being produced by the device is not a real flame. In one embodiment, the device includes a sintered nozzle that receives a stream of steam and outputs a steam cloud, a steam accelerator for applying a linear stream of air to steam cloud output by the sintered nozzle, and a lighting system to project desired colors onto the linear steam cloud.

Abstract: The invention is directed to special effect device that is used to produce a simulated flame that has the shape and, if desired, the color characteristics of the flame produced by a jet afterburner. In one embodiment, the device includes a steam system for providing a stream of steam, a steam accelerator for applying a high-speed and highly linear stream of air to steam provided by the steam system to produce at steam cloud with a highly linear shape similar to the shape of the flame produced by a jet afterburner, and a lighting system to project desired colors onto the linear steam cloud.
