PURPOSE: An apparatus and a method for supplying fuel gas are provided to stably supply fuel gas to a place where uses high-pressure fuel or low-pressure fuel by installing a first flow control valve, a forceful vaporizer, and a first check valve in a forceful vaporization line. CONSTITUTION: An apparatus for supplying fuel gas comprises an evaporated gas supply line(14), an evaporated gas compressor(141), an evaporated gas heater(142), an LNG supply line(12), an LNG pump, a first bypass valve(121), a forceful vaporization line(13), a first flow control valve(131), a forceful vaporizer(132), and a first check valve(133). The evaporated gas supply line is extended from an LNG storage tank to a place where uses low-pressure fuel. The evaporated gas compressor and heater are installed in the evaporated gas supply line. The LNG supply line is extended from the LNG tank to a re-condenser. The LNG pump and the first bypass valve are installed in the LNG supply line. The forceful vaporization line is installed between the rear of the LNG pump and the rear of the evaporated gas compressor. The first flow control valve, the forceful vaporizer, and the first check valve are installed in the forceful vaporization line. |
