본 발명의 실시예에 따른 선박용 연료 공급 시스템은, 선박용 엔진에 공급되는 연료로 액화 암모니아가 저장되는 저장 탱크, 저장 탱크와 연결되어 엔진에 연료를 공급하는 제1 배관, 제1 배관에 연결된 부스터 펌프, 엔진으로부터 배출되는 잉여 암모니아를 부스터 펌프의 전단으로 회수시키는 제2 배관, 저장 탱크와 부스터 펌프 사이를 연결하는 제3 배관, 제3 배관에 연결되어 저장 탱크 내에서 발생되는 BOG를 가압하는 압축기, 압축기를 통해서 가압된 BOG를 응축 및 액화시키는 애프터 쿨러, 압축기 및 애프터 쿨러 후단과, 이코노마이저 사이를 연결하는 제10 배관, 및 압축기 및 애프터 쿨러 후단과, 이코노마이저의 사이에서, 제10 배관에 연결된 열회수기를 포함한다.

    In accordance with an embodiment of the present invention, a fuel supply system for a vessel includes: a storage tank storing liquefied ammonia as fuel to be supplied to an engine for a vessel; a first pipe connected with the storage tank to supply the fuel to the engine; a booster pump connected with the first pipe; a second pipe collecting residual ammonia discharged from the engine into the front end of the booster pump; a third pipe connecting the storage tank with the booster pump; a compressor connected to the third pipe to compress BOG produced from the inside of the storage tank; an aftercooler compressing and liquefying the BOG compressed through the compressor; a tenth pipe connecting the compressor and the rear end of the aftercooler with an economizer; and a heat recovering unit connected to the tenth pipe between the economizer, and the rear end of the aftercooler and the compressor. Therefore, the present invention is capable of preventing hardening or solidification due to a temperature difference between low-temperature ammonia and lubricating oil.
