Abstract
método e dispositivo para produzir metal reduzido direto. trata-se de método para produzir material de metal reduzido direto que compreende as etapas de: a) carregar material de metal a ser reduzido em um espaço de fornalha (120); b) evacuar uma atmosfera existente do espaço de fornalha (120) de modo a alcançar uma subpressão dentro do espaço de fornalha (120); c) fornecer, em uma etapa de aquecimento principal, calor e gás hidrogênio ao espaço de fornalha (120), de modo que gás hidrogênio aquecido aqueça o material de metal carregado a uma temperatura alta o suficiente de modo que óxidos de metal presentes no material de metal sejam reduzidos, fazendo, por sua vez, com que o vapor d?água seja formado; e d) condensar e coletar o vapor d?água formado na etapa c em um condensador (160) abaixo do material de metal carregado; caracterizado pelo fato de que as etapas c e d são realizadas pelo menos até que uma sobrepressão de atmosfera hidrogenada tenha sido alcançada dentro do espaço de fornalha (120), e pelo fato de que nenhum gás hidrogênio é evacuado do espaço de fornalha (120) até que a dita sobrepressão tenha sido alcançada. a invenção também se refere a um sistema.
