Jacket Water Cooling System Of Main Engine Marine Diesel о 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. For most diesel engines, a jacket water discharge temperature of about 180of is preferred with a temperature rise through the engine in the range of 8 to15of. 6.1.1.2 engine coolant water is the most common coolant used in diesel engines. however, water alone presents the possibility of corrosion, mineral deposits, and freezing. Jacket water heater in the line is a steam jacket water heater. when the engine is shut down steam heating maintains the engine in a state of readiness reducing the time needed for starting. attempting to start the engine without heating can lead to poor combustion, poor lubrication and thermal shocking. It is assumed from rpm 100 127 the temperature outlet of jacket water is constant at 83,1 o c. the result of temperature inlet & outlet and heat available from jacket water cooling system than.

The engine jacket cooling water outlet temperature should be kept as high as possible, but not higher than 80°c, and if the temperature is lower than 50°c, it should be increased to min. 50°c before start up. jacket cooling water system with a built in preheater there are two options for the position of the preheater in the jacket cooling. The h.t circuit in the central cooling system mainly comprises of the jacket water system of the main engine where the temperature is quite high. the h.t water temperature is maintained by low temperature fresh water and the system normally comprises of the jacket water system of the main engine, fw generator, dg during standby condition, lube oil filter for stuffing box drain tank.
