Zusammenfassung:	The present invention provides a dust coal provides an apparatus and method for blowing dust coal into a melting furnace. The apparatus for blowing dust coal into a melting furnace comprises: at least one or more dust coal blowing-in burner installed on an upper portion of a charging material of a melting furnace by blowing the dust coal into the upper portion of the charging material of the melting furnace, thereby improving oxidation of reduction gas generated in the melting furnace, increasing ore reducibility, reducing a weight of carbon dioxide in the melting furnace, and simultaneously increasing a weight of carbon monoxide; and a controller controlling a blow-in amount of the dust coal provided into the dust coal blowing-in burner. Moreover, the method of blowing dust coal into a melting furnace comprises: a step of blowing-in dust coal using a dust coal blowing-in burner installed in the melting furnace; and a step of controlling a blowing-in environment of the dust coal into the melting furnace. 용융로의 장입물 상부에서 미분탄을 취입함으로써 용융로에서 발생하는 환원가스의 산화도를 개선하면서 광석 환원율을 향상시켜 용융로 내의 이산화탄소 비중은 낮춤과 동시에 일산화탄소 비중을 높여줄 수 있도록, 용융로의 장입물 상부에 적어도 하나 이상 설치되는 미분탄 취입 버너; 및 상기 미분탄 취입 버너로 공급되는 미분탄의 취입량을 제어하도록 제공된 제어부를 포함하는 용융로의 미분탄 취입장치 및, 상기 용융로에 설치된 미분탄 취입 버너를 이용하여 미분탄을 취입하는 단계;와 상기 미분탄의 용융로 취입 환경을 제어하는 제어단계를 포함하는 미분탄 취입방법을 제공한다.
