According to one embodiment of the present invention, an ammonia fuel supply apparatus is provided. According to one embodiment of the present invention, the ammonia fuel supply apparatus includes: a storage tank storing liquefied ammonia; a fuel supply pipe supplying the liquefied ammonia from the storage tank to a combustion engine; a pressure boosting pump connected to the fuel supply pipe to increase supply pressure of the liquefied ammonia supplied from the storage tank; a buffer tank connected to the fuel supply pipe at the rear end of the pressure boosting pump to temporarily store the liquefied ammonia; a BOG discharge pipe connected with the storage tank to discharge ammonia produced from the natural evaporation of the liquefied ammonia; and a compressor connected with the BOG discharge pipe to compress the ammonia at pressure requested by the combustion engine. As the BOS discharge pipe at the rear end of the compressor is connected to the buffer tank, the ammonia compressed by the compressor is brought into gas-liquid contact with the liquefied ammonia in the buffer tank to be liquefied, and then, supplied to the combustion engine together with the liquefied ammonia. Therefore, the present invention is capable of more safely and efficiently disposing of ammonia which is a toxic substance.

    본 발명의 일 실시예에 의해 암모니아 연료 공급 장치가 제공된다. 본 발명의 일 실시예에 따른 암모니아 연료 공급 장치는, 액상암모니아를 저장하는 저장탱크와, 저장탱크로부터 액상암모니아를 연소기관으로 공급하는 연료공급관과, 연료공급관에 연결되어 저장탱크로부터 공급되는 액상암모니아의 공급압력을 높이는 승압펌프와, 승압펌프 후단의 연료공급관에 연결되어 액상암모니아를 임시 저장하는 버퍼탱크와, 저장탱크와 연결되어 액상암모니아가 자연 기화되어 생성된 암모니아를 배출하는 BOG배출관, 및 BOG배출관에 연결되며 연소기관에서 요구하는 압력으로 암모니아를 압축하는 압축기를 포함하되, 압축기 후단의 BOG배출관은 버퍼탱크에 연결되어, 압축기에서 압축된 암모니아는 버퍼탱크에서 액상암모니아와 기액 접촉하여 액화된 후 액상암모니아와 함께 연소기관으로 공급될 수 있다.
