The present invention relates to a circulating fuel filtration system and, more specifically, to a circulating fuel filtration system including a fuel tank for providing a main engine with fuel undergone a series of refinement processes. The circulating fuel filtration system comprises: a filter for receiving fuel from the fuel tank and removing foreign materials from the fuel; a first pipe connecting the fuel tank to the filter and including a pump arranged between the fuel tank and the filter; and a second pipe for connecting the filter to the first pipe to provide the fuel overflowing from the filter to the first pipe. Therefore, the size of an overflow tank can be reduced as the circulating fuel filtration system blocks the fuel back-flushed from the filter to the overflow tank by differential pressure between before and after the filter. Moreover, costs for purifying fuel can be reduced by reducing the amount of inflow coming into a purifier. |
