Method for manufacturing direct reduced iron and DRI manufacturing equipment

Abstract

A method for manufacturing Direct Reduced Iron wherein iron ore is reduced in a DRI shaft by a reducing gas including hydrogen obtained by thermal cracking of methane inside a plasma torch, the reducing gas further including top gas coming from the DRI shaft and a DRI manufacturing equipment including a DRI shaft (1) and a plasma torch (40), wherein the plasma torch is connected on one side to a methane supply (41) and, on the other side, to the DRI shaft (1), the DRI shaft being provided with a recycling loop allowing to inject its top gas back in the DRI shaft.
