Abstract
The present invention provides a combination reforming/reducing shaft furnace for the production of direct reduced iron that utilizes one or more burden uniformity enhancers, such as one or more rotating/reciprocating mixing shafts, one or more stationary flow aids, one or more wall structures/variations, one or more agitators, or the like for ensuring that reforming and reducing in the shaft furnace take place evenly across the width of and throughout the depth of the burden in the shaft furnace.
