ABSTRACT:
A smoke generator which generates cold smoke having the buoyant properties of smoke produced by a fire. The density of the smoke can be varied to simulate any desired fire plume temperature by adding helium or other lighter than air gas to it. This produces a smoke which rises and spreads just like the smoke from a fire but without requiring that a fire be used to produce the smoke.
