According to the present invention, disclosed is a fuel gas supply system capable of enhancing re-liquefaction efficiency of evaporated gas. The system comprises: a storage tank to store liquefied and evaporated gas; a fuel gas supply line including a first and a second compressing unit to sequentially compress the evaporated gas of the storage tank, and supplying the evaporated gas compressed through the first and the second compressing unit; a re-liquefaction line receiving and re-liquefying a part of the compressed evaporated gas; a nitrogen separator receiving a part the evaporated gas passing through the first compressing unit to separate a nitrogen component included in the evaporated gas; a second fuel gas supply line to supply, to a second engine, a first gas flow separated by the nitrogen separator to contain the nitrogen component with a first concentration; and a nitrogen reduction line to re-supply, to the rear end of the first compressing unit, a second gas flow separated by the nitrogen separator to contain the nitrogen component with second concentration.

    연료가스 공급시스템이 개시된다. 본 발명의 실시 예에 의한 연료가스 공급시스템은 액화가스 및 증발가스를 수용하는 저장탱크, 저장탱크의 증발가스를 순차적으로 가압하는 제1압축부 및 제2압축부를 구비하고 제1압축부 및 제2압축부를 통과하여 가압된 증발가스를 제1엔진으로 공급하는 제1연료가스 공급라인, 가압된 증발가스의 일부를 공급받아 재액화시키는 재액화라인, 제1압축부를 통과한 증발가스의 일부를 공급받아 이에 함유된 질소성분을 분리하는 질소분리기, 질소분리기에 의해 분리되어 제1농도의 질소성분을 함유하는 제1가스흐름을 제2엔진으로 공급하는 제2연료가스 공급라인 및 질소분리기에 의해 분리되어 제2농도의 질소성분을 함유하는 제2가스흐름을 제1압축부 후단으로 재공급하는 질소저감라인을 포함하여 제공될 수 있다.
