PURPOSE: A fuel gas supply apparatus which directly evaporates LNG using boiler steam is provided to optimally control necessary temperature for burning LNG by adjusting the flow rate of steam circulating in an evaporator. CONSTITUTION: A fuel gas supply apparatus which directly evaporates LNG using boiler steam comprises a fuel gas supply line(L1), a supply pump(22), an evaporator(23), a boiler(30), and a steam circulation line(34). The supply pump is installed in the middle of the fuel gas supply line, and delivers LNG to an engine(10) from an LNG tank. The evaporator is installed in the fuel gas supply line between the supply pump and the engine to evaporate the LNG. The boiler generates steam for heating a room or generating power. The steam circulation line is installed to circulate the steam in the evaporator, and evaporates the LNG by the heat exchange between the steam and the LNG. |
