An apparatus for generating smoke includes a closed chamber having a top cover, and a metal air inlet tube, a metal air outlet tube and a metal suction tube extending through the cover. An electric coiled-wire heating element is positioned transversely in the chamber and connected electrically at each end to the metal air inlet tube and the metal suction tube. A spray dispenser is attached to the top cover and positioned over the heating element and is operably connected to a supply of smoke-producing fluid, the dispenser being configured to spread and drop controlled quantities of the smoke- producing fluid onto the heating element. Separate controls are provided for controlling flow of the fluid onto the heating element for controlling smoke production, and for controlling flow of air for carrying smoke through a delivery line for use. An orifice and also a condenser is positioned at an outlet of the smoke-producing chamber to better distribute and control smoke in the air, and to reduce oil droplets and heat in the smoke-carrying air. Variations are provided to show manual, semi-automatic, and automatic apparatus.
