An ammonia fuel supply device is provided that can minimize evaporative gas generated and discharged from a fuel storage tank. The ammonia fuel supply device according to an embodiment of the present invention comprises: a fuel storage tank for storing liquid ammonia; a first fuel supply line for supplying the liquid ammonia from the fuel storage tank to a first combustion engine; a first recovery line for connecting the first combustion engine and the first fuel supply line and delivering the liquid ammonia or ammonia recovered from the first combustion engine back to the first fuel supply line; a second fuel supply line branched from at least one of the first fuel supply line and the first recovery line and connected to a second combustion engine to supply the liquid ammonia or ammonia to the second combustion engine; a discharge line for discharging evaporation gas of the liquid ammonia generated from the fuel storage tank; and a first knockout drum connected to the discharge line to separate the liquid ammonia contained in the evaporation gas and deliver the liquid ammonia to the first recovery line.

    연료저장탱크에서 발생되어 배출되는 증발가스를 최소화할 수 있는 암모니아 연료 공급장치가 제공된다. 본 발명의 일 실시예에 의한 암모니아 연료 공급장치는 액상암모니아를 저장하는 연료저장탱크와, 연료저장탱크로부터 제1 연소기관으로 액상암모니아를 공급하는 제1 연료공급라인과, 제1 연소기관과 제1 연료공급라인을 연결하여, 제1 연소기관으로부터 회수되는 액상암모니아 또는 암모니아를 다시 제1 연료공급라인으로 전달하는 제1 회수라인과, 제1 연료공급라인과 제1 회수라인 중 적어도 하나에서 분기되어 제2 연소기관으로 연결되어, 액상암모니아 또는 암모니아를 제2 연소기관으로 공급하는 제2 연료공급라인과, 연료저장탱크에서 발생하는 액상암모니아의 증발가스를 배출하는 배출라인과, 및 배출라인 상에 연결되어 증발가스에 포함된 액상암모니아를 분리하여 제1 회수라인으로 전달하는 제1 녹아웃드럼을 포함한다.
