摘要： A multiple moving hearth furnace (10) having a furnace housing (11) with at least two moving hearths (20) positioned laterally within the furnace housing, the hearths moving in opposite directions and each moving hearth (20) capable of being charged with at least one layer of iron oxide and carbon bearing material at one end, and being capable of discharging reduced material at the other end. A heat insulating partition (92) is positioned between adjacent moving hearths of at least portions of the conversion zones (13), and is capable of communicating gases between the atmospheres of the conversion zones of adjacent moving hearths. A drying/preheat zone (12), a conversion zone (13), and optionally a cooling zone (15) are sequentially positioned along each moving hearth (30) in the furnace housing (11).

摘要： A hearth furnace (10) for producing metallic iron material has a furnace housing (11) with a drying/preheat zone (12) capable of providing a drying/preheat atmosphere for reducible material, a conversion zone (13) capable of providing a reducing atmosphere for reducible material, a fusion zone (14) capable of providing an atmosphere to at least partially reduced metallic iron material, and optionally a cooling zone (15) capable of providing a cooling atmosphere for reduced material containing metallic iron material. A movable hearth (20) within the furnace housing (11) in a direction through the drying/preheat zone (12), then the conversion zone (13), then the fusion zone (14), and then the cooling zone (15). A separation barrier 30 is positioned within at least a portion of the conversion zone (13), the separation barrier (30) separating the conversion zone (13) into a combustion region (32) and a reducing region (31) with the reducing region (31) adjacent the hearth (20) and the combustion region (32) adjacent the reducing region (31) and spaced from the hearth (20).
