The present invention provides an ammonia fuel vessel capable of effectively treating exhaust gas discharged from an incineration unit incinerating surplus ammonia. According to one embodiment of the present invention, the ammonia fuel vessel comprises: a hull; a fuel tank installed on the hull to store liquid ammonia; a boiler receiving the liquid ammonia or ammonia created as the liquid ammonia is vaporized from a fuel supply pipe connected to the fuel tank to combust the liquid ammonia or the ammonia to create steam; a posttreatment device installed on an exhaust pipe of the boiler to reduce at least one among nitrous oxide, nitrogen oxide, and ammonia slip included in exhaust gas discharged from the boiler; an incineration unit receiving the ammonia from an incineration treatment pipe connected to at least one between the fuel tank and the fuel supply pipe to incinerate the ammonia; and a supply pipe supplying exhaust gas discharged from the incineration unit to at least one between the boiler and the posttreatment device.
