Abstract

A method of generating nontoxic smoke is taught. The method comprises: (a) submerging a nontoxic smoke creating device in a liquid coolant while preventing entry of coolant into said device; said device includes a composition which comprises: (1) a first reactant selected from the group consisting of potassium chlorate, potassium perchlorate, potassium dichromate, cesium nitrate, and potassium nitrate; and (2) a second reactant serving as a reduction agent; (b) activating said smoke creating device by reacting said composition comprising said first reactant and said second reactant, to create solid particulate products having a diameter of about one micron or less which create the nontoxic smoke; and (c) passing said solid particulate products into said coolant through at least one downwardly directed tuyere hydraulically connected at or near the top of said device without any accompanied destruction of said nontoxic smoke creating device.
