Industrial Rising Film Evaporators

In Rising Film Evaporator, due to the ascending force of the vapour bubbles, which are produced during boiling, the liquid and vapours flow upwards in a parallel flow. Simultaneously the vapour quantity also increses therby forming a climbing film on the walls of a tube, Due to this there is a high turbulence in the liquid and these evaporators are advantages for heat sensitive, highly viscous and moderately scaling liquids

The temperature difference in the rising film evaporators should be high between the heating chest and boiling chamber to ensure the circulation and formation of a climbing film.
