Abstract

Abstract An evaporating system, characterized in that a shell is sectioned with substantially horizontal partition walls, with a plurality of effective units which operate under different pressures are arranged in the vertical direction in the order of pressure, with the unit of higher pressure located upwardly. Brine remained in the bottom of an upper effective unit is spread over the next effective unit of lower pressure from jet holes provided at the partition wall by the head of the brine and pressure difference between the two effective units. A part of the brine is flash-evaporated and the remainder is distributed to the outer surface of a heat transfer tube in the effective unit of lower pressure. The brine is heated by steam generated in the upper effective unit and is partly condensed.
