Beschreibung
Zusammenfassung:	Provided is a tuyere assembly of an apparatus of manufacturing an ingot iron, including: a tuyere where a gas flow channel blowing an oxygen-containing gas into a melting gasifier is formed, and a fuel blow tube spaced apart from the gas flow channel and passing through the tuyere to blow an auxiliary fuel into the melting gasifier, in which the fuel blow tube includes two tubes connected to each other, such that damage of the tuyere is prevented, a combustion focus distance is reduced to improve combustion efficiency of the auxiliary fuel, and abrasion of the blow tube according to blowing of the auxiliary fuel is minimized.
