According to the present invention, a vessel to be propelled using ammonia as fuel comprises: an ammonia supply line for supplying ammonia, stored in an ammonia storage tank, to an ammonia engine; a return gas recovery line for transferring return gas, discharged from the ammonia engine and mixed with oil, to the ammonia supply line; a collecting tank for separating the oil mixed with the return gas flowing through the return gas recovery line; an exhaust gas discharge line having a SCR reducing nitrogen oxides in exhaust gas discharged from the ammonia engine; and a boil-off gas supply line for supplying boil-off gas, generated in the ammonia storage tank, to the SCR. Therefore, the energy efficiency of the whole system can be improved.

    본 발명에 따른 선박은, 암모니아를 연료로 이용하여 추진하는 것으로서, 암모니아 저장탱크에 저장된 암모니아를 암모니아 엔진에 공급하는 암모니아 공급라인; 상기 암모니아 엔진에서 배출되며 오일이 혼합된 리턴가스를 상기 암모니아 공급라인으로 전달하는 리턴가스 회수라인; 상기 리턴가스 회수라인을 통해 유동하는 리턴가스에 혼합된 상기 오일을 분리하는 수집탱크; 상기 암모니아 엔진에서 배출되는 배기가스 중의 질소 산화물을 환원시키는 SCR을 구비하는 배기가스 배출라인; 및 상기 암모니아 저장탱크에서 발생하는 증발가스를 상기 SCR로 공급하는 증발가스 공급라인을 포함한다.
