PROBLEM TO BE SOLVED: To solve such a problem that, in a small-sized ship, fuel oil transferred from a fuel oil storage tank has high viscosity while being supplied to a fuel oil settling tank at a low temperature of 25 to 35°C, such a state that heating cannot reach a preset temperature according to natural convection of the fuel oil is incurred and the fuel oil discharged from the fuel oil settling tank causes abrupt temperature change/drop to result in a temperature fall of the fuel oil which cannot be solved by a cleaner heater.SOLUTION: In a fuel oil cleaner heating system of a small-size ship, fuel oil properly heated by combining heating means (in claim 1) which heats fuel oil outputted from a fuel oil settling tank 38 while mixing the fuel oil with heated fuel oil outputted from a diesel engine 60 and heating means (in claim 2) which circulates a part of the heated fuel oil outputted from a cleaner supply pump 44 from a circulating pipe line 48 to a pipe line 41 of the fuel oil settling tank 38 and performs mixing and heating is supplied to a fuel oil cleaning device 49, and the cleaned fuel oil is supplied to a fuel oil common use tank 52 through a pipe line. |
