Abstract

a presente invenção se refere a um método para a redução direta de uma matéria-prima contendo óxido de metal para a formação de um material metálico por meio do contato com um gás de redução quente em uma unidade de redução (1), em que o produto do processo de redução direta é descarregado da unidade de redução por meio de um dispositivo de descarga de produto que é lavado com um gás de vedação, é arrastado do gás de ventilação e em seguida desempoeirado. pelo menos uma parte do gás de ventilação desempoeirado é usada como uma fonte de energia durante a combustão para a produção do gás de redução, e/ou como um componente de um gás de combustão de forno durante um processo de combustão de modo a aquecer o gás de redução, e/ou como um componente do gás de redução. o pedido se refere ainda a um dispositivo para a execução do método.
