NOZZLE COOLING SYSTEM AND SHIP HAVING THE SAME

摘要

PURPOSE: A nozzle cooling system and a ship including the same are provided to radiate the heat generated in a fuel injection nozzle with a water cooling method. CONSTITUTION: A nozzle cooling system(100) comprises a tank(110) which stores fuel being supplied to a fuel injection nozzle, a radiating unit(120) which radiates the heat generated in the fuel injection nozzle(22), a circulation cooling line(130) which circulates fuel between the tank and the radiating unit to cool the fuel injection nozzle, and a fuel level sensing unit(112) which senses the amount of fuel in the tank. A ship comprising the nozzle cooling system includes an engine(10) which includes a fuel injection unit(20) comprising the fuel injection nozzle and a fuel supply line(30) which supplies fuel to the fuel injection nozzle.
