ABSTRACT:
A compact evaporation apparatus includes an evaporator vessel with a sloped, bottom chamber. A combustion chamber is mounted to a top of the vessel, with a burner mounted to a top of the combustion chamber, the combustion chamber sized to achieve total combustion of an air/gas mixture supplied to the burner before being released below a liquid surface in the vessel. At least one turbulence diverter plate is located within the vessel beneath the liquid surface, the diverter plate being a submerged perforated plate extending horizontally from the combustion chamber, such that hot combustion gasses are released below the diverter plate, and as large gas bubbles rise to the surface they pass through small perforations in the diverter plate, thereby breaking large, hot gas bubbles into small bubbles, the gas to liquid contact area being maximized to increase system efficiency.
