In accordance with the present invention, a fuel supply system for a ship comprises: one or more fuel storage tanks (10) for storing ammonia fuel (1); a fuel supply tank (20) connected to the fuel storage tank (10) and for supplying the ammonia fuel (1) to the ammonia engine (E) of a ship (S); a first gas-liquid separator (30) for separating the surplus ammonia fuel (2), recovered from the ammonia engine (E), into liquid ammonia (LA) in a liquid state and gaseous ammonia (GA) in a gaseous state; and a heat exchanger (50) for exchanging the heat between the gaseous ammonia (GA) separated by the first gas-liquid separator (30) and the boil-off gas (BOG) generated in the fuel storage tanks (10) or the fuel supply tank (20). The temperature of the gaseous ammonia (GA) separated by the first gas-liquid separator (30) is lowered by the heat exchanger (50). Therefore, the fuel supply system for a ship can efficiently use ammonia fuel.

    본 발명에 따른 선박용 연료 공급 시스템은 암모니아 연료(1)를 저장하는 하나 이상의 연료 저장 탱크(10); 상기 연료 저장 탱크(10)에 연결되며 선박(S)의 암모니아 엔진(E)에 상기 암모니아 연료(1)를 공급하는 연료 공급 탱크(20); 상기 암모니아 엔진(E)에서 회수되는 잉여 암모니아 연료(2)를 액체 상태의 액체 암모니아(LA)와 기체 상태의 기체 암모니아(GA)로 분리하는 제1 기액 분리기(30); 그리고 상기 제1 기액 분리기(30)에 의해 분리된 기체 암모니아(GA)와 상기 연료 저장 탱크(10) 또는 상기 연료 공급 탱크(20)에서 발생된 증발 가스(BOG)를 열교환시키는 열교환기(50);를 포함하고, 상기 제1 기액 분리기(30)에 의해 분리된 상기 기체 암모니아(GA)의 온도는 상기 열교환기(50)에 의해 하강한다.
