Fresh Water Generator Principle Working Line Diagram Parts And Functions Plate type fresh water generator line diagram. working. main engine jacket water passes through the evaporator at 80 degree. feed sea water enters the evaporator through the orifice at the feed inlet. due to low pressure in the chamber, sea water boils and get converted to steam. the carry over water droplet and water spray is removed by demister. A detailed line diagram of a tube type fresh water generator on board ship is shown below. click on the diagram to enlarge. plate type fresh water generator. working principle of plate type fresh water generator is same as that of submerged tube type. only difference is the type of heat exchangers used.
Fresh Water Generator Principle Working Line Diagram Parts And Functions A simple line diagram shown below gives clearer picture about the plant. click on the diagram to enlarge. working principle with saturated steam heating. in addition to engine jacket cooling water heating, saturated live steam can alternatively be used as heating medium for the shell and tube freshwater generator. Open the sea water discharge valve from where the water is sent back to the sea after circulating inside the fresh water generator. close the vacuum valve situated on top of the generator. now start the sea water pump and check the pressure of the pump. the pressure is generally 3 4 bars. wait for the vacuum to build up. The process of generating fresh water is achieved via distillation. there are three main methods employed for generating fresh water from seawater, these are boiling, evaporating and reverse osmosis (ro). most marine vessels and industrial plants produce fresh water using either evaporators or ro plants. A fresh water generator is a device that converts seawater into potable water. it is an essential component of any vessel that spends extended periods at sea, as it provides a reliable source of fresh water for drinking, cooking, and other purposes. the working principle of a fresh water generator is based on the process of reverse osmosis.

Close the evaporator feed water valve. stop the pump ejector. shut down overboard valve of fresh water generator. open the vacuum breaker valve so that the side pressure of the shell is equal to. The seawater will boil and evaporate at around 40 60 o c due to the vacuum conditions made by the air brine ejector. the water spray and droplets are partly removed from the vapor by the use of the deflector mounted on top of the evaporator. the separated water and droplets fall back to the brine and will be extracted again by the ejector.
