Abstract
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.
