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 heat exchanger applying heat to the liquefied ammonia discharged from the knockout drum to evaporate the same; a BOG discharge pipe connected with the storage tank to discharge ammonia produced from the natural evaporation of the liquefied ammonia; a compressor connected with the BOG discharge pipe to compress the ammonia; and a cooler connected with the BOG discharge pipe at the rear end of the compressor to cool the ammonia. The forcedly evaporated ammonia, which is produced through forced evaporation in the heat exchanger, is supplied to the BOG discharge pipe at the front end of the cooler, and the BOG discharge pipe at the rear end of the cooler can be connected to the fuel supply pipe at the front end of the pressure boosting pump or the storage tank. Therefore, the present invention is capable of increasing the efficiency of the apparatus while preventing a pressure rise in the storage tank.
