According to the present invention, provided is a fuel heating apparatus for a vessel, including: a main housing installed in an oil tank of a vessel while having a cylindrical structure having a space provided therein, having a steam introduction pipe formed on the rear side of the bottom to introduce heating steam supplied from the outside, and having a steam discharge pipe formed on the front side of the bottom to discharge the introduced heating steam to the outside again; a circulation housing having a cylindrical structure having a space provided therein while installed in the oil tank, and placed to be opposed to the main housing while kept spaced apart therefrom; a plurality of steam circulation flow path pipes installed with both longitudinal ends combined with the main housing and the circulation housing respectively such that the main housing and the circulation housing are connected, and arranged side by side in the oil tank in vertical and forward/backward directions while kept spaced apart from each other; a plurality of first vertical oil flow path pipes having both longitudinal directions combined with the top and bottom of the main housing to penetrate the main housing in a vertical direction such that heavy fuel oil in the oil tank can pass through the inside of the main housing, and arranged side by side in the main housing in forward/backward directions while kept spaced apart from each other; and a plurality of second vertical oil flow path pipes having both longitudinal directions combined with the top and bottom of the circulation housing to penetrate the circulation housing in a vertical direction such that heavy fuel oil in the oil tank can pass through the inside of the main housing, and arranged side by side in the circulation housing in forward/backward directions while kept spaced apart from each other. Therefore, the present invention is capable of increasing heating efficiency for heavy fuel oil while stably delivering thermal energy.

    본 발명은, 내부에 공간이 마련된 통 구조를 가지는 상태로 선박의 오일탱크 내부에 설치하며, 하단의 후측에는 외부에서 공급되는 가열 증기를 유입되게 하는 증기유입관이 형성되고, 하단의 선측에는 유입된 가열 증기를 다시 외부로 배출되게 하는 증기배출관이 형성된 메인 하우징, 오일탱크의 내부에 설치한 상태로 내부에 공간이 마련된 통 구조를 가지며, 메인 하우징에 이격상태로 마주보도록 배치하는 순환 하우징, 메인 하우징과 순환 하우징을 연결하도록 길이방향 양단을 메인 하우징과 순환 하우징에 각각 결합 설치하며, 오일탱크의 내부에 상하방향 및 전후방향으로 상호 이격상태로 나란하게 복수개를 배열한 증기 순환유로관, 오일탱크 내 중연료유가 메인 하우징의 내부를 통과할 수 있게 메인 하우징을 상하방향으로 관통하도록 길이방향 양단을 메인 하우징의 상단 및 하단에 결합하며, 메인 하우징의 내부에 전후방향으로 상호 이격상태로 나란하게 복수개를 배열한 제1수직 오일유로관, 오일탱크 내 중연료유가 순환 하우징의 내부를 통과할 수 있게 순환 하우징을 상하방향으로 길이방향 양단을 순환 하우징의 상단 및 하단에 결합하며, 순환 하우징의 내부에 전후방향으로 상호 이격상태로 나란하게 복수개를 배열한 제2수직 오일유로관을 포함하는 선박용 연료 가열장치를 제공한다.
