The invention provides a marine fuel supply system and an ammonia BOG recycling system and method thereof. The ammonia BOG recycling system comprises a buffer tank, a BOG compressor, a BOG condenser, a gas-liquid separation tank and a controller which are sequentially connected. The buffer tank is connected with the ammonia fuel cabin and is used for storing ammonia BOG generated by the ammonia fuel cabin; the BOG compressor is used for pressurizing ammonia BOG; the BOG condenser is used for carrying out heat exchange treatment on the supercharged ammonia BOG to obtain liquid ammonia which meets the temperature requirement of an ammonia engine and contains the ammonia BOG; and the gas-liquid separation tank is used for carrying out gas-liquid separation on the liquid ammonia containing the ammonia BOG to complete conversion of the ammonia BOG and realize recycling of the ammonia BOG. Ammonia BOG in the ammonia fuel cabin is effectively treated and reused, the risk of structural fracture of the ship cabin is reduced, the utilization rate of fuel is increased, and harm caused by direct emission of ammonia gas into the atmosphere is reduced.

    本发明提供了一种船用燃料供应系统及其氨BOG回收再利用系统和方法,其中氨BOG回收再利用系统包括依次连接的缓冲罐、BOG压缩机、BOG冷凝器、气液分离罐和控制器;缓冲罐与氨燃料舱相连接,用于存储氨燃料舱产生的氨BOG;BOG压缩机用于对氨BOG进行增压处理;BOG冷凝器用于对增压后的氨BOG进行换热处理,得到满足氨发动机温度要求的包含了氨BOG的液氨;气液分离罐用于对包含了氨BOG的液氨进行气液分离,完成对氨BOG的转化,实现对氨BOG的回收再利用。有效地将氨燃料舱中的氨BOG进行处理并再利用,减少船舶舱室结构破裂的危险,增加了燃料的利用率,减少了氨气直接排放到大气中所带来的危害。
