Working Principle The combined brine/air ejector driven by the ejector pump creates a vacuum in the system in order to lower the evaporation temperature of the feedwater. The feedwater is introduced into the evaporator section stage 1 through an orifice, and is distributed into every second plate channel (evaporation channels). The hot water is distributed into the remaining channels, thus transferring its heat to the feedwater in the evaporation channels. Having reached boiling temperature - which is lower than at atmospheric pressure the feed water undergoes a partial vaporation, and the mixture of generated vapour and brine enters the separator vessel, where the brine is separated from the vapour and is introduced into every second channels of the evaporator stage 2 as feed water. The vacuum steam generated in the first stage passes via a demister into the remaining channels in stage 2 of the evaporator section
