ABSTRACT:
The present invention's fog generating apparatus has a mixing chamber. A steam nozzle in the mixing chamber injects high pressure steam into the chamber. The injected steam entrains ambient air, pulling it through an air opening into the mixing chamber. The steam and air mix to form humid air. Cryogenic fluid, preferably liquid nitrogen, is injected through a nozzle, which is positioned in the path of the humid air. The cryogenic fluid rapidly cools the warm, humid air which generates large quantities of fog. Depending of the way the steam is injected and the design of the mixing chamber, the present invention can generate slow or fast moving fog.
