<p>An apparatus and method for controllably generating simulated smoke from a simulated smoke-generating fluid has a vaporizing chamber (1) with an inlet (11a), an outlet (12a) and walls (13) extending therebetween. The chamber (1) has a center line (15) which is declined from the horizontal from inlet wall (11) to outlet wall (12). A lower surface (2) in the chamber (1) terminates near the inlet (11a) in a surface terminus (20) of defined width. Smoke fluid is distributed along the terminus (20) and flows by gravity downwardly across the surface (2) as a thin film. A heater (6) and heater control (7) control the heating of the chamber (1) and the surface (2) to a temperature sufficient to cause the smoke fluid to vaporize into a vapor. An ejector (8) ejects the vapor out of the chamber (1) through the outlet (12a) into a mixing device (10) which communicates with heated air for mixing the vapor and heated air and producing the simulated smoke.</p> |
