Abstract
Heat exchange is improved in natural-circulation and flowthrough evaporators in which the liquid to be evaporated is admitted to heating tubes and evaporators therein as the fluid rises in the tubes. According to the invention the liquid is preheated under a higher hydrostatic pressure than at the inlet to the heating tubes by treatment with direct steam, preferably in a steam-jacketed siphon tube forming a downcomer from a separator removing concentrate from the vapors emerging from the evaporator.
