In accordance with one embodiment of the present invention, provided is an ammonia fuel supply apparatus. In accordance with 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 increasing 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 increasing 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 increasing pump; a fuel circulation pipe connected to the knockout drum to circulate the liquefied ammonia in the knockout drum to the fuel supply pipe; a BOG discharge pipe connected with the storage tank and discharging ammonia produced by the natural gasification of the liquefied ammonia; a compressor connected with the BOG discharge pipe to compress the ammonia; and a BOG pressing pipe having one end connected to the BOG discharge pipe at the rear end of the compressor and having the other end connected to the knockout drum to supply the compressed ammonia to the knockout drum. Therefore, the present invention is capable of more safely and effectively disposing of ammonia which is a toxic substance.
