FUEL SUPPLY SYSTEM

摘要

Disclosed is a fuel supply system. The fuel supply system can improve liquefaction efficiency by liquefying evaporation gas generated in a storage tank using liquefied gas and liquid nitrogen. According to an embodiment of the present invention, the fuel supply system includes: a storage tank storing the liquefied gas; an auxiliary tank receiving the liquefied gas from the storage tank and storing the liquefied gas; a fuel supply line treating the liquefied gas stored in the auxiliary tank and supplying the treated liquefied gas to an engine; a nitrogen tank storing the liquid nitrogen; a reliquefaction line liquefying the evaporation gas of the storage tank by heat-exchanging with a heat exchanger and the liquefied gas in the auxiliary tank and returning the liquefied evaporation gas to the storage tank; and a nitrogen circulation line heat-exchanging the liquid nitrogen of the nitrogen tank with the heat exchanger and the liquefied gas in the auxiliary tank and returning the heat-exchanged liquid nitrogen to the nitrogen tank.
