Abstract

본 발명은 장입물 인접층이 장입물과 그 장입물 위쪽으로 지향된 하나이상의 버너로부터 방출하는 연소가스 사이에 형성되며, 그 장입물 인접층은 장입물에 대해 연소가스와는 다른 산화효과를 가지는 직화로에 관한 것이다.

Description

직화로 내에서 장입물을 가열 또는 용해시키는 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 실시에 이용가능한 하나의 노 배치에 대한 단순 횡단면도, 제2도는 본 발명에 따른 층별화된 노 내 대기의 개략도, 제5도는 공기분리장치를 갖는 본 발명에 따른 방법의 실시예를 도시하는 단순 개략도.

Claims (10)

  1. 직화로 내에서 장입물을 가열 또는 용해시키기 위한 방법에 있어서, (a) 장입물 위쪽에 설치된 직화식 버너로부너 전달되는 복사열에 상기 장입물을 노출시키도록 노 안으로 장입물을 도입하는 단계와, (b) 초당 15.24m(50fbs) 이하의 평균속도에서 상기 직화식 버너로부터 상기 노의 내부로 연료 및 산화물을 공급하고, 열을 생성하고 연소가스를 발생시키도록 노 내에서 연료 및 산화제를 연소시키는 단계와, 그리고 (c) 감소된 양의 상기 연소가스를 함유하는 장입물 인접 대기층을 형성하도록 초당 15.24m(50fbs) 이하의 속도로 상기 직화식 버너와 상기 장입물 상이의 노 내측으로 장입물 인접 가스를 주입함으로써, 상기 장입물 인접가스가 없을 때 존재하는 것들과 다른 산화특성을 갖는 노 내의 대기에 상기 장입물을 노출시키는 단계를 포함하는 것을 특징으로 하는 방법.
  2. 제1항에 있어서, 상기 연소가스는 상기 장입물에 대해서 대체로 불활성인 것을 특징으로 하는 방법.
  3. 제1항에 있어서, 상기 장입물 인접 가스는 상기 장입물의 산화 작용을 증대시키는 것을 특징으로 하는 방법.
  4. 제1항에 있어서, 상기 장입물 인접 가스는 질소를 함유하는 것을 특징으로 하는 방법.
  5. 제1항에 있어서, 상기 장입물 인접 가스의 흐름은 층류인 것을 특징으로 하는 방법.
  6. 제1항에 있어서, 상기 장입물 인접 가스는 상기 장입물이 용해될 때 장입물을 통과해 노의 내측을 통과하는 것을 특징으로 하는 방법.
  7. 제1항에 있어서, 상기 장입물은 강철을 포함하는 것을 특징으로 하는 방법.
  8. 제1항에 있어서, 상기 장입물은 알루미늄을 포함하는 것을 특징으로 하는 방법.
  9. 제1항에 있어서, 상기 장입물은 유리를 포함하는 것을 특징으로 하는 방법.
  10. 제1항에 있어서, 상기 산화제 및 상기 장입물 인접 가스는 공기를 질소부화 유체 및 산소부화 유체로 분리시키는 공기분리 장치로부터 모두 취해지는 것을 특징으로 하는 방법.
