Abstract
This article deals with research of the film evaporation process in evaporator-condenser of a distillation desalination plant. Presented plant is used for desalination of seawater by consecutive processes of evaporation and condensation. Energy is added to plant by means of steam compressor which increases steam pressure from the last stage and feeds it to first stage. In evaporator-condenser the processes of film condensation of steam inside tubes and film evaporation of seawater on external surface of tubes take place. The regime of film evaporation is maintained at a certain flow rate of feed water, the change of which causes both the change of the heat transfer ratio and possible regime break. The film evaporation regime boundaries are determined as well as the influence of the feed water flow rate on heat transfer ratio. Also, a possibility to regulate steam condensation process by means of feed water rate change is investigated.
