PURPOSE: A system for supplying a natural gas fuel is provided to decrease a necessity of maintenance and a repair, and to be safer by not using seawater and by using an evaporation heat of a liquefied natural gas (LNG) more efficiently. CONSTITUTION: A system for supplying a natural gas fuel comprises a fuel supply line, a vaporizer (210) and a heater (310), a refrigerant circulating line, an engine heat transfer line, and an engine heat connection line (551). The fuel supply line supplies a fuel to a used place from a natural gas storage tank (1). The vaporizer and heater are successively installed at the fuel supply line. The refrigerant circulating line is connected to the vaporizer, and an air handling unit (220) and a heat exchanger are successively installed. The engine heat transfer line is connected to the heater. The engine heat connection line is branched from the engine heat transfer line of a front end of the heater, connected to the heat exchanger, and connected to the engine heat transfer line of a rear end of the heater again. |
