PURPOSE: A fuel supply device using the recirculation of fuel supply gas is provided to minimize the occupying space of a ship by reducing the entire size of a device and remove a need for an additional evaporator to product and control separate make-up gas. CONSTITUTION: A fuel supply device using the recirculation of fuel supply gas comprises an LNG vessel(10), an LNG evaporator(11), an LNG pressure pump(12), a pressure maintaining compressor(13), a heater(16), and a gas supply line(14). The LNG evaporator evaporates LNG supplied from the LNG vessel. The LNG pressure pump presses LNG in the LNG vessel to a predetermined pressure to supply LNG to the LNG evaporator. The pressure maintaining compressor is connected to between the LNG evaporator and a ship engine to be able to re-circulate a portion of evaporated LNG supplied to the ship engine to the LNG evaporator. |
