Provided is a fuel heating device for a ship capable of maintaining temperature of fuel and lowering viscosity. The fuel heating device for a ship comprises: a housing having a rectangular structure in which an upper plate, a bottom plate, a left plate, a right plate, a front plate and a rear plate are formed and mounted inside an oil tank in which heavy fuel oil is stored, wherein the housing includes a vapor inflow pipe formed on the left plate to introduce vapor supplied from the outside and a vapor outflow pipe formed on the right plate to discharge the introduced vapor to the outside; guide plates arranged inside the housing in zigzags by turns to be spaced from each other in a back and forth direction inside the housing so that the inside of the housing is divided into several receiving spaces; a plurality of oil passage pipes arranged side by side to penetrate the housing in a vertical direction, wherein an upper end is combined with the upper plate and a lower end is combined with the bottom plate so that the heavy fuel oil of the oil tank passes the receiving spaces of the housing; and a diffused vapor supply pipe having a pipe structure of which one end is closed, wherein the other end is connected to the vapor inflow pipe and a plurality of diffusion holes are formed in an outer circumferential surface so that the vapor introduced into the vapor inflow pipe is diffused and discharged to the inside of the housing.

    본 발명은, 상측판과 바닥판과 좌측판과 우측판 및 선측판과 후측판으로 구성된 사각통 구조를 가지는 상태로 선박의 중연료유가 저장된 오일탱크 내부에 설치하며, 좌측판에는 외부에서 공급되는 증기를 유입되게 하는 증기유입관이 형성되고, 우측판에는 유입된 증기를 다시 외부로 배출되게 하는 증기배출관이 형성된 하우징, 하우징의 내부를 전후방향으로 복수개의 수용공간으로 구획하도록 하우징의 내부에 전후방향으로 이격되게 지그재그 방식으로 교대 배치되는 가이드판, 오일탱크의 중연료유가 하우징의 각 수용공간을 통과하도록 하우징을 상하방향으로 관통하게 상단은 상측판에 결합하고, 하단은 바닥판에 결합하며, 상호 나란하게 복수개를 배열한 오일유로관, 일단이 밀폐된 관 구조를 가지는 상태로 타단은 증기유입관에 연결하고, 외주면에는 증기유입관으로 유입된 증기를 하우징의 내부로 확산 배출되게 상호 이격되게 복수의 확산공이 관통 형성된 확산증기공급관을 포함하는 선박용 연료 가열장치를 제공한다.
