Abstract:

A non-toxic smoke generator for simulating the smoke of a fire includes an inner cylindrical shell surrounded in spaced relation by a thermally insulated outer casing to form an air flow passage there between through which compressed air heated by electric air heaters is caused to flow in a helical pattern to heat the shell to a temperature above the vaporization temperature of a vaporizable smoke substance. The smoke substance, such as propylene glycol, polyethylene glycol 200 or mineral oil, is pumped from a reservoir through a supply pipe having a coiled preheating portion disposed in the space between the shell and housing and is sprayed through a wide spray atomizing nozzle into heated vaporization chamber where it is vaporized and discharged as nontoxic smoke.
