Starting

  • Make sure seawater ejector pump suction, discharge, and overboard valves are open.
  • Start the ejector pump. Seawater pressure at the air ejector must be at about 3 bar or more.
  • Wait for the vacuum to build up inside the freshwater generator shell. (About 92 % vacuum).
  • Open the feed water valve to feed seawater to the evaporator. Adjust the feed water pressure. Normally for desired feed water pressure (thereby the flow).
  • Open the main engine jacket cooling water inlet and outlet to the evaporator gradually.
  • Open the air vent clock at the top of the evaporator to make sure the evaporator is filled with jacket co
  • Switch on the salinity alarm panel for measuring the purity of the freshwater produced.
  • There will be a sight glass provided at the suction line for the distillate pump.
  • Make sure to condense the distillate pump and an open discharge valve to lead-generated water to specified storage tanks.
  • Do checks while running the Fresh Water Generator
  • Through the sight glass provided in the evaporator shell, observe the flashing of water.
  • Also, check for the brine level inside. It should not be too high or too low.
  • Shell temperature must be around 50 degrees Celsius.
  • Make sure that the shell vacuum is more than 90% from the vacuum gauge.
  • Check the seawater inlet and outlet temperature of the condenser.
  • Ensure seawater pressure at the air-ejector inlet is more than 3 bars.
