An evaporator is a type of heat exchanger device that facilitates evaporation by utilizing conductive and convective heat transfer, which provides the necessary thermal energy for phase transition from liquid to vapour. Within evaporators, a circulating liquid is exposed to an atmospheric or reduced pressure environment causing it to boil at a ...
An evaporator, distiller or distilling apparatus is a piece of ship's equipment used to produce fresh drinking water from sea water by distillation. As fresh water is bulky, may spoil in storage, and is an essential supply for any long voyage, the ability to produce more fresh water in mid-ocean is important for any ship.
Rising Film Evaporator Diagram. A rising film or vertical long tube evaporator is a type of evaporator that is essentially a vertical shell and tube heat exchanger. The liquid being evaporated is fed from the bottom into long tubes and heated with steam condensing on the outside of the tube from the shell side.
The most suitable evaporator will have the highest heat transfer coefficient per dollar of equipment cost. [2] In optimising the design of an evaporator, another important consideration is the steam economy (kg of solvent evaporated per kilogram of steam used).

English: Diagram of a vacuum insulated evaporator. No refrigeration unit is needed for the storage vessel because the liquid oxygen remains cold due to the efficiency of the vacuum container and the loss of latent heat as oxygen vaporizes.

Aerosol of microscopic water droplets suspended in the air above a cup of hot tea after the water vapor has sufficiently cooled and condensed. Water vapor is an invisible gas, but the clouds of condensed droplets refract and scatter the sunlight and are thus visible.
