선박용 엔진의 연료 공급 시스템이 개시된다. 상기 선박용 엔진의 연료 공급 시스템은, 저장탱크로부터 배출된 증발가스를 압축시키는 다단압축기; 상기 다단압축기에 의해 압축된 증발가스의 일부를 상기 저장탱크로 보내는 라인 상에 설치되는 제2 밸브; 상기 다단압축기에 의해 압축된 증발가스 중, 상기 제2 밸브를 통과하여 상기 저장탱크로 보내지지 않은 증발가스의 일부 또는 전부를, 상기 저장탱크로부터 배출된 증발가스를 냉매로 열교환시켜 냉각시키는 열교환기; 및 상기 열교환기에 의해 냉각된 유체를 팽창시키는 제1 감압장치;를 포함하고, 상기 다단압축기는 상기 저장탱크 내부 압력이 제1 설정값 이하가 되면 정지하고, 상기 제2 밸브의 개도를 조절하여 상기 저장탱크 내부 압력을 상기 제1 설정값을 초과하도록 유지한다.

    Disclosed is a system for supplying fuel of a marine engine. The system for supplying fuel of a marine engine comprises: a multi-stage compressor for compressing evaporated gas discharged from a storage tank; a second valve installed on a line for sending part of the evaporated gas compressed by the multi-stage compressor to the storage tank; a heat exchanger for partially or wholly discharging the evaporated gas which has passed through the second valve and has not been sent to the storage tank among the evaporated gas compressed by the multi-stage compressor, by cooling the evaporated gas discharged from the storage tank with a refrigerant to cool the evaporated gas; and a first decompression apparatus for expanding fluid cooled by the heat exchanger. The multi-stage compressor stops when the internal pressure of the storage tank becomes lower than a first set value, and maintains the internal pressure of the storage tank above the first set value by adjusting an opening degree of the second valve.
