Claims (2)
- 입자형 제1철재료, 특히 미리환원된 스폰지철로부터 강철이전의 산출물 또는 용융선철을 생산하고, 그것과 더불어 석탄을 첨가하고 그곳을 통해서 산소가 흐르는 코우크스 입자들로 형성된 고정층과 그 위에 놓여진 코우크스 입자의 유동층이 형성되어져 있고, 그 유동층상에 제1철재료를 채워넣게되는 멜트-다운 가스화장치의 벽을 침투해 있는 노즐관(2)의 수단으로 산소를 함유하는 가스를 송풍하여 멜트-다운 가스화장치(1)에서 환원가스를 생산하는 방법에 있어서, 산소를 함유하는 가스가 흐르는 고정층(Ⅱ)의 아래에 산소를 함유하는 가스가 흐르지 않는 고정층(Ⅰ)을 마련하고, 산소를 함유하는 가스가 흐르는 그 고정층(Ⅱ)의 상부에 산소가 전혀 없거나 있다면 낮은 함량을 갖는 가스가 흐르는 유동층(Ⅲ)을 마련하는 것을 특징으로 하는 상기의 방법.
- 제1항에 있어서, 산소를 함유하는 가스가 흐르는 고정층(Ⅱ)의 높이는 멜트-다운 가스화장치(Ⅰ)내로 도입되어진 석탄의 알갱이크기 분포에 의해서 조절되고 유지되는 것을 특징으로 하는 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
