Plate-type Fresh Water Generator for Ship

The sea water enters into the FWG plant at the condenser for cooling the water vapor, 
flows through the condenser. Then a little quantity is fed into the evaporating chamber and about half of them evaporating to vapor, the sea water is heated by the cylinder cooling water of main engine. 
The rest quantity of sea water is led to the brine/air ejector, where brine and air is take off, and was discharged to overboard. 
The pressure inside the chamber is less than atmosphere (vacuum), in this way the evaporating temperature usually is lower than 45 degree. The vapor rises from the evaporating chamber, which flows throug the demister where brine mist is removed, and pure steam condensed to liquid in the condenser.
