선박용 엔진의 연료 공급 시스템이 개시된다. 상기 선박용 엔진의 연료 공급 시스템은, 저장탱크로부터 배출되는 증발가스를 다단계로 압축시키는 다단압축기; 상기 다단압축기에 의해 압축된 증발가스를, 상기 저장탱크로부터 배출된 증발가스를 냉매로 열교환시켜 냉각시키는 열교환기; 상기 저장탱크로부터 배출된 액화천연가스를, 상기 열교환기에 의해 1차로 냉각된 유체에 분사하여, 유체를 2차로 냉각시키는 액화천연가스 분사 장치; 및 상기 액화천연가스 분사 장치에 의해 냉각된 유체를 팽창시키는 제1 감압장치;를 포함하고, 상기 제1 감압장치로 보내지는 유체의 온도가 일정하게 유지되어, 재액화 성능이 일정하게 유지되는 것을 특징으로 한다.

    Disclosed is a fuel supply system of a vessel engine. According to the present invention, the fuel supply system of a vessel engine comprises: a multistage compressor to compress evaporation gas discharged from a storage tank through multiple stages; a heat exchanger to heat-exchange and cool the evaporation gas compressed by the multistage compressor by using evaporation gas discharged from the storage tank as a refrigerant; a liquefied natural gas (LNG) spray device primarily spraying LNG discharged from the storage tank to secondarily cool a fluid; and a first decompression device to expand the fluid cooled by the LNG spray device. Accordingly, the temperature of the fluid supplied to the first decompression device is constantly maintained, thereby constantly maintaining reliquefication performance.
