The invention also relates to an apparatus for the treatment of feed materials in the form of fines, in particular feed materials containing metals.
종래 기술에는 연속 구동되는 다수의 유동층 반응기를 이용하는 연합 조작이 공지되어 있다. 문서 AT 403 381 B에는 제 1 유동층 반응기로부터 노정 가스의 일부가 연속 구동되는 제 2 유동층 반응기 옆을 통과하는 것에 대해 설명되어 있다.In the prior art, associative operations using multiple fluidized bed reactors of continuous operation are known. Document AT 403 381 B describes the passage of part of the top gas from the first fluidized bed reactor next to the second fluidized bed reactor which is continuously driven.
종래 기술에 따른 유동층-환원 공정에서는 미분 형태의 철광석이 충분히 환원되지 않는다는 문제가 종종 발생한다. 기술 개발의 목적 때문에, 예열 반응기 내지는 예비 환원 반응기 내에서 철광석이 환원될 때 자철석이 생성될 수 있는지에 대해 관찰되었다. 자철석은 매우 조밀한 조직을 이루기 때문에 추가의 환원을 방해한다. 이러한 자철석 생성을 방지하기 위해 예컨대 유동층 내 가스 분위기가 조정될 수 있다. 그러나 사실상 가스 분위기의 변동폭은 매우 제한되어 있다.In the fluidized-bed reduction process according to the prior art, a problem often arises that the fine ore iron is not sufficiently reduced. For the purpose of technical development, it has been observed whether magnetite can be produced when iron ore is reduced in a preheating or preliminary reduction reactor. Magnetite has a very dense structure, thus preventing further reduction. In order to prevent this magnetite formation, for example, the gas atmosphere in the fluidized bed can be adjusted. In practice, however, fluctuations in the gas atmosphere are very limited.

It is a very economical operation.
