ABSTRACT:
A smoke producing system for efficiently producing reduced toxin smoke includes a heating chamber heated by a heat source. A coil passes into and through the heating chamber to deliver a smoke producing substance, typically a liquid, to the hottest portion of the heating chamber. The substance is heated above a flash point of the substance before it is released from the coil into the hottest part of the heating chamber where it is immediately converted to smoke. The smoke then passes from the hottest portion of the chamber through a convoluted path to an outlet port. In a particular embodiment, the smoke producing system incorporates a fan assembly used as the heat source and for directing the smoke produced in a desired direction.
