Claims (10)

  1. 효과적으로 서로 독립된 반응 공간속으로 분출되는 산소함유 가스분사들 속에서 반응생성가스가 재연소되는 것을 특징으로 하는, 주로 CO 및 H2로 되는 반응생성가스를 재연소하므로써 또 용융물에 탄소질 연료를 투입하므로써 공정의 열수지에 소요되는 에너지를 발생하고 산화철이 액상속에서 실질적으로 분해되는 철광성 융해법.
  2. 제 1항에 있어서 가스분사의 반응공간이 반응가스의 유동방향쪽으로 하나 다음 하나씩으로 위치하고 분해위치는 제 2반응 영향점 또는 재연소가스분사에서 더 작은 것을 특징으로 하는 철광석 융해법.
  3. 제 1항 내지 2항에 있어서 용융로 속의 용융물의 고분해 위치구역에서 강한 액교반이 유지되는 것을 특징으로 하는 철광석 융해법.
  4. 제 1항 내지 3항 중 어느 하나의 항에 있어서 둘 이상의 단계의 재연소가 한 개의 용기 또는 두개가 서로 연결된 용기 속에서 수행되는 것을 특징으로 하는 철광석 융해법.
  5. 제 1항 내지 4항 중 어느 하나의 항에 있어서 원광석은 제 2반응공간 또는 재연소용 또 다른 반응공간 속에 투입되는 것을 특징으로 하는 철광석 융해법.
  6. 제 1항 내지 5항 중 어느 하나의 항에 있어서 대량전환은 두 개의 재연소용 반응공간사이의 액상속에서 일어나는 것을 특징으로 하는 철광석 융해법.
  7. 제 1항 내지 6항 중 어느 하나의 항에 있어서, 탄소질연료가 재연소용 제 1반응공간 즉 최고분해 위치 구역속의 용융물 속으로 투입되는 것을 특징으로 하는 철광석 융해법.
  8. 제 1항 내지 7항 중 어느 하나의 항에 있어서 산소함유가스분사가 물표면에 대하여 경사지게 반응공간 속으로 분출되는 것을 특징으로 하는 철광석 융해법.
  9. 제 1항 내지 8항 중 어느 하나의 항에 있어서 30% 내지 50%의 재연소율이 반응로속의 제 1재연단계 즉 고분해위치에 설정되고 60% 내지 100%의 재연소율이 제 2재연소 단계에 설정된 것을 특징으로 하는 철광석 융해법.
  10. 제 1항 내지 9항 중 어느 하나의 항에 있어서 예열공기가 재연소용 산소함유 가스로써 사용되는 것을 특징으로 하는 철광석 융해법.
