Abstract
resumo patente de invenção: "método e dispositivo para produção de gusa". a presente invenção refere-se a um método e dispositivo de redução de material contendo óxido de ferro, que forma um leito sólido (7) em um meio de redução e o material contendo óxido de ferro é convertido em material pré-reduzido (9) no eixo de redução (1) por meio de pelo menos um gás de pré-redução introduzido no leito sólido (7) a uma pressão p1. pelo menos uma parte do dito material pré-reduzido (9), preferivelmente todo o material pré-reduzido (9), é introduzido a partir do eixo de redução (1) em um gaseificador fundidor (4) no qual é finalmente reduzido por meio de um gás de redução (8) sob uma pressão p2. um gás superior possuindo uma pressão p3 é desviado para fora da câmara acima do leito sólido (7) do eixo de redução (1) e pelo menos um gás de exaustão de poeira (6) possuindo uma pressão p4 é desviado do leito sólido (7) para fora do eixo de redução (1). a relação p1>p4 e p1>p3 se aplica, preferivelmente, também p4>p3.
