More Information
Summary:The application relates to a method for the direct reduction of feedstock, containing metal-oxide to form metallic material, by contact with hot reduction gas in a reduction assembly (1), the product of the direct reduction process being discharged from the reduction assembly (1) by means of a product discharge apparatus (3), which is flushed with seal gas, and being drawn off from the vent gas and subsequently dedusted. The vent gas undergoes a dry dedusting process and the content of at least one gaseous constituent is reduced by catalytic conversion or combustion. The application further relates to apparatus for carrying out the method.
