2102790 9220418 PCTABScor01 Apparatus and method for evaporating a liquid includes a casing (12); a plurality of vertically extending plate-type heating elements (11) within the casing, each heat element having an outer surface and an inner surface and a vertical edge, the heat elements being spaced and forming an open channel (14) along the vertical edge between adjacent elements; a distributor (21) above the heating elements for distributing the liquid over the elements; an inlet (23) connected to the heating elements for introducing a heating medium and for generating vapor from the liquid; and a wall-like device (40, 42) mounted within the casing facing the spaces between the heating elements for collecting and guiding the vapor generated in the evaporator. Preferably, the wall-like element includes a droplet separating device (30) formed by vertically elongated spaced elements (31) having a substantially U-shaped cross-section with inwardly pointing vertical edges (32).
