PURPOSE:To improve combustibility of fuel and save consumption of the fuel, by providing a recirculating circuit whereby the fuel oil containing a large amount of impurities in the bottom part of a service tank is introduced to the suction side of a feed pump for a centrifugal separator and recirculated to be processed by using the centrifugal separator. CONSTITUTION:Unpurified fuel oil of low quality in a double bottomed tank 1 is suitably heated in a heater 6 and then fed to a centrifugal separator 7a by using a feed oil pump 5a, to be purified, thereafter fed to a service tank 8a. Then, fuel oil in the service tank 8a is fed to a fuel tank 20 of a Diesel engine 9 through a primary filter 14, flow meter 15, mixing tank 16, booster pump 17, heater 18 and a secondary filter 19. While, a part of the fuel oil in the tank 8a is returned from a recirculating cleaning line 22 to a pipe on the suction side of the feed pump 5a and fed again to the centrifugal separator 7a, being repeatedly subjected to a purifying process. |
