ABSTRACT: The invention is concerned with a method and an apparatus for the vaporization of liquid in a heat exchanger of the vertical-tube type, in which exchanger the vapour or liquid delivering the heat is passed through the tubes of the group (7) of tubes in the heat exchanger prefer- ably from the bottom upwards. The group (7) of tubes is passed through at least one nozzle plate (18) or nozzle basin (22) so that nozzle openings (16, 20, 23) surrounding the tubes are formed between the openings in the nozzle plates and the tubes. In the heat exchanger the liquid to be vaporized is passed to the mantle side into the upper part of the heat exchanger or into each nozzle basin of the heat exchanger separately and is guided so as to flow downwards on the outer face of the group (7) of tubes as a liquid film. The vapour develo- ped from the liquid film is, by means of vapour flow passages formed into the group (7) of tubes, passed from the lower part of the heat exchanger further into its object of use or from each component unit (1, 2, 3) of the heat exchanger further into its object of use.
