When the main engine is not running or the ship is passing through colder areas it is necessary to keep the jacket water temperature at 80 85 degree celsius. to do this job a pre heater is provided, which will not allow the jacket water temperature below 80 85 degree celsius. fresh water generator: fresh water generators act as a cooling.

Main Engine Jacket Cooling Water System High temperature cooling water system. the high temperature (ht) cooling water system, also known as the jacket cooling water (jcw) system, is used for cooling the cylinder unit components of the main engine and heating of the fuel oil drain pipes. the design of the jacket cooling water piping varies, depending on the engine type and fuel sul. Jacket water cooling pump. the pumps are to be of the centrifugal type. the flow capacity must be within a range from 100 to 110% of the capacity stated. the pump head of the pumps is to be determined based on the total actual pressure drop across the cooling water system i.e. pressure drop across the main engine, jacket water cooler, three way. This makes the cooling water system design more flexible. a cooling water temperature of approximately 80°c (176°f) and cooling water pressure of 3 bar (44 psi) is standard for most engines operating under load. cooling water is sometimes referred to as ' jacket water ' due to the 'jacket' of water surrounding the combustion space. Cooling water system temperature controls function to: keep shutdown engine warm to enhance startup. keep the operating engine hot for improved efficiency but cool enough to prevent overheating of critical parts. enhance engine turbocharging by cooling turbo compressed intake combustion air. figure 6 1 jacket water cooling system with keepwarm.

The jacket water temperature regulating valve is a three way temperature controlled valve that controls the coolant temperature by directing coolant to the jacket water heat exchanger, as required, to maintain coolant temperature at the desired operating level. jacket water cooling water pump the jacket water cooling water pump is an engine. The main engine is cooled by two separate but linked systems: an open system (sea to sea) in which water is taken from and returned to the sea (seawater cooling), and a closed system where freshwater is circulated around an engine casing (freshwater cooling). freshwater is used to cool machinery directly, whereas seawater is used to cool.
