The invention belongs to the technical field of ships, and particularly relates to a system for an LNG transport ship to store ammonia fuel through an isolation cabin. The system comprises an isolation cabin, a lightering pump, a supply valve, a circulating pump, a temperature sensor, a seawater heat exchanger, a seawater pump and a control unit. The ammonia fuel is stored in the isolation cabin of the LNG transport ship, heat exchange is carried out between the ammonia fuel in the isolation cabin of the LNG transport ship and external seawater, the temperature of the ammonia fuel in the isolation cabin is kept between-40 DEG C and-34 DEG C, a proper low-temperature environment is provided for the ammonia fuel, and the storage space problem of the ammonia fuel on the LNG transport ship is solved; and meanwhile, consumption of a high-grade heat source of the ship is avoided, and good economical efficiency is achieved.
本发明属于船舶技术领域,具体涉及一种LNG运输船利用隔离舱储存氨燃料系统。该系统包括隔离舱、驳运泵、供给阀、循环泵、温度传感器、海水换热器、海水泵、控制单元。本发明将氨燃料储存在LNG运输船隔离舱内,通过LNG运输船隔离舱内的氨燃料和外部海水进行换热,使隔离舱内氨燃料的温度维持在‑40℃~‑34℃之间,为氨燃料提供了合适的低温环境,解决了氨燃料在LNG运输船上的储存空间难题,同时还避免了对船舶高品位热源的消耗,具有较好的经济性。
