The invention relates to a ship fuel preheating system. The ship fuel preheating system is characterized in that a fuel preheating branch pipeline and a fuel conveying branch pipeline are arranged between a storage bin and a sedimentation cabinet. A main pipeline is shared and is divided into two branches near the sedimentation cabinet, a preheating pump is arranged on one branch and provides high temperature fuel for the storage bin, a transfer pump is arranged on the other branch and conveys heated heavy oil to the sedimentation cabinet, and the two branches are provided with stop check valves in the corresponding directions so as to avoid pipeline direction malposition. A small compartment is arranged at one corner of the storage bin, and a first partition plate is arranged in the middle of the small compartment and divides the compartment into two parts in the X direction. A pipe A and a pipe B are arranged in a first sub-compartment, the upper right corner of the first partition plate is provided with a hole, the lower left corner of a second partition plate is provided with a hole, and the two holes are in opposite angle arrangement. Small holes are formed at the bottoms of partition plates to be used for sweeping. An upper plate of the compartment is provided with a plurality of air holes, so as to guarantee timely overflow of generated steam. The pipe A and the pipe B are communicated with the main pipeline and provided with regulating valves respectively.
