device for the direct reduction of iron oxides and its application

摘要

Device and method for the direct reduction of iron oxides, comprising a reactor defining in its middle-upper part a reduction zone (110) inside which the reaction takes place, means (15) to introduce the load from above the reactor, means to introduce the gassy current into at least a section of the reactor in correspondence with the reduction zone (110), means to remove the reduced material, and means (20) to discharge the exhaust fumes, the reactor including an upper mouth (12) communicating with said reduction zone (110) for the introduction of the mineral iron and a lower aperture (13) through which the reduced iron exits, wherein said reduction zone (110) has a truncated cone conformation tapering downwards.
