The present invention relates to a fuel gas supply apparatus for a vessel, capable of supplying fuel gas to an engine of a vessel. The fuel gas supply apparatus includes: an LNG storage tank storing LNG; a tank pressure increasing part connected to the LNG storage tank, heating and vaporizing some of the LNG in the LNG storage tank, and then, resupplying the same to the LNG storage tank while increasing pressure of the LNG storage tank; a fuel gas supply part connected with the LNG storage tank and the engine, and vaporizing the LNG in the LNG storage tank, and then, supplying the same in a gas state to the engine; an engine heat recovery part connected with the engine, and recovering heat from the engine produced during the operation of the engine; a waste heat recovery part connected with an exhaust line of the engine, and recovering heat from high-temperature exhaust gas produced during the operation of the engine; and a vaporized heat supply line connected with the tank pressure increasing part, the fuel gas supply part, the engine heat recovery part and the waste heat recovery part, and vaporizing the LNG while delivering the heat recovered from the engine heat recovery part and the waste heat recovery part such that the heat is circulated to the tank pressure increasing part and the fuel gas supply part. Therefore, the present invention is capable of enabling the LNG to be stably used as fuel for the engine.

    본 발명은, 선박의 엔진으로 연료가스를 공급하는 선박용 연료가스 공급장치에 있어서, LNG를 저장하는 LNG저장탱크, LNG 저장탱크와 연결하며, LNG저장탱크 내 일부의 LNG를 가열하여 기화한 후, 다시 LNG저장탱크로 공급하면서 LNG저장탱크의 압력을 상승시키는 탱크 압력상승부, LNG저장탱크 및 엔진과 연결하며, LNG저장탱크의 LNG를 기화시킨 후 가스상태로 엔진에 공급하는 연료가스 공급부, 엔진과 연결하며, 엔진의 동작시 발생하는 엔진의 열을 회수하는 엔진열 회수부, 엔진의 배기라인과 연결하며, 엔진의 동작시 발생하는 고온의 배기가스로부터 열을 회수하는 폐열 회수부, 탱크 압력상승부와 연료가스 공급부와 엔진열 회수부 및 폐열 회수부와 연결하며, 엔진열 회수부와 폐열 회수부로부터 회수되는 열을 탱크 압력상승부와 연료가스 공급부로 순환 이동되게 전달하면서 LNG를 기화되게 하는 기화열 공급라인을 포함하는 선박용 연료가스 공급장치를 제공한다.
