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.
