Provided is a system for preheating fuel for a ship, which is to improve energy efficiency. The system for preheating fuel for a ship comprises: an electric heat tank which has an inner space inside; a steam inlet unit which is provided on one end of the inner space, and communicates with a steam suction line connected to a steam boiler; a steam outlet unit which is provided on the other end of the inner space, and communicates with a steam discharge line having a control valve selectively opening a flow path to one of the steam boiler and a low-temperature heat exchange line; a plurality of electric heat pipe units which cross the inner space to connect the steam inlet unit and the steam outlet unit; a fuel injection hole which supplies fuel to one side of the electric heat space formed between the electric heat pipe units; a fuel discharge hole which is formed on the other side of the electric heat space so that the fuel preheated through the electric heat pipe units is discharged; an induction heating coil unit which is wound around an outer circumference of the electric heat tank, and performs induction heating for the inside of the electric heat space; a temperature sensor which detects the inner temperature in the electric heat space; and a control unit which controls the operation of the induction heating coil unit and the control valve in accordance with the temperature detected by the temperature sensor.

    에너지효율이 개선되도록 본 발명은 내부에 내부공간을 구비하는 전열탱크; 상기 내부공간의 일단에 구비되되, 스팀보일러와 연결된 스팀 흡입라인과 연통되는 스팀인렛부; 상기 내부공간의 타단에 구비되되, 상기 스팀보일러 및 저온열교환라인 중 어느 하나와 선택적으로 유로를 개통하는 제어밸브가 구비된 스팀 토출라인과 연통되는 스팀아웃렛부; 상기 내부공간을 횡단하여 상기 스팀인렛부와 상기 스팀아웃렛부를 연결하는 복수개의 전열관부; 상기 전열관부들 사이에 형성된 전열공간의 일측으로 연료를 공급하는 연료주입구; 상기 전열관부들을 통해 예열된 연료가 토출되도록 상기 전열공간의 타측으로는 연료토출구; 상기 전열탱크의 외주에 권취되되, 상기 전열공간 내부를 유도가열하는 유도가열코일부; 상기 전열공간 내부 온도를 감지하는 온도센서; 및 상기 온도센서에 의해 감지된 온도에 따라 상기 유도가열코일부 및 상기 제어밸브의 구동을 제어하는 제어부를 포함하는 선박연료 예열시스템을 제공한다.
