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 temperature control unit connected to the fuel supply pipe at the rear end of the pressure boosting pump to increase the temperature of the liquefied ammonia supplied to the combustion engine; a knockout drum storing the liquefied ammonia discharged through a branch pipe branched from the fuel supply pipe at the rear end of the pressure boosting pump; a first BOG collection pipe connected with the storage tank, and reliquefying first ammonia produced from the natural evaporation of the liquefied ammonia to supply the same to the storage tank or the fuel supply pipe; and a second BOG collection pipe connecting the knockout drum with the first BOG collection pipe to supply second ammonia produced from the evaporation of the liquefied ammonia stored in the knockout drum, to the first BOG collection pipe. Therefore, the present invention is capable of increasing the efficiency of the apparatus while preventing a pressure rise in the storage tank.
