Abstract
1439603 Film evaporation UNITED KING- DOM ATOMIC ENERGY AUTHORITY 18 June 1973 [22 June 1972] 29396/72 Heading B1B A film evaporator plant has at least one metal tube exterior as an evaporating surface supporting a filament whose surface wettability with reference to water is less than that of the evaporating surface, and distribution means for applying a heating fluid into the bore of the tube, the intersection of the surface of the tube exterior and the filament supported thereby forming at least one cavity which acts as a nucleation site when a film of liquid is applied to the tube exterior. A method of evaporating a liquid e.g. aqueous comprises flowing a film of the liquid over a plane evaporating surface bearing a filament whose surface is substantially less wettable by the liquid than the material of the evaporating surface, the filament cross section normal to its longitudinal axis being such that nucleation sites are formed at positions where the surface of the filament intersects the evaporator surface and applying heat to the evaporator surface remote from that bearing the filament to boil liquid from the film. The filament may be in the form of a mesh, and may be of polypropylene or copper supported on a copper alloy evaporating surface, or may be of surface oxidised copper wire supported on a nickel-copper alloy evaporating surface.
