  "textContent": "A marine liquid ammonia fuel supply and fuel recycling system, comprising an ammonia fuel engine, a liquid ammonia supply system, a liquid ammonia recycling system, and a liquid ammonia nitrogen purging ventilation system. According to the present invention, unconsumed liquid ammonia fuel in a pipeline can be recycled while the high-pressure liquid supply (pressure≥70 bar, and temperature is 45±10°C) of marine liquid ammonia fuel is realized, such that a large amount of fuel can be saved, the amount of the ammonia fuel discharged to a ventilation mast is reduced, and the safety of a ship and personnel is improved.",
