Abstract:

An improved method of and apparatus rendering water-based fluid waste stream evaporation operations environmentally and otherwise safe, involving separately and independently existing the hot gas stream produced by fuel combustion and the vaporized fluid-air exhaust stream resulting from heat-vaporizing of the fluid, independently directing the streams in opposite directions toward one another and to a common region, and applying fan suction immediately at said region to exert the sole control of withdrawing the streams simultaneously.
