Falling film heat exchanger
WebJan 24, 2024 · A falling film evaporator (FFE) is a form of vertically oriented shell and tube (S&T) heat exchanger used to separate two or more liquids with different boiling points. Two compartments are included in a shell and tube heat exchanger. Its most fundamental function is to put a heating or cooling fluid, referred to as the media, into indirect but ... WebAbstract. Falling film heat exchanger includes circular areas for evenly distributing feed liquid and/or heat exchange liquid to the tube interior and/or exterior surfaces. The circular areas may be defined by a liquid porous material, slots in an O-ring or vertical slots in the holes through and to which the tubes are joined.

WebTo compare the heat and mass transfer characteristics of the conventional heat exchanger and desiccant-coated heat exchanger, Sun et al. found that the heat transfer capacity of DCHE was reduced by 30%, pressure drop was increased by 60% (based on the designed experimental testing). This was because of the heat resistance of the desiccant coating. WebIn falling film heat exchangers, the fluid enters the heat exchanger at the top of the films and the fluid flows down due to gravity. The film can be heated or cooled. The diagram on the left shows how a falling film heat exchanger is used to evaporate a liquid product.
