Abstract:
A method for introducing fine particulate material (4) of ferruginous particles into a fluidized bed reduction unit (1) having a fluidized bed (24), wherein the temperature in the fluidized bed (24) is more than 300° C., and wherein the fine particulate material (4) is introduced directly into the fluidized bed (24) and/or into a free space (25) above the fluidized bed (24) by means of a burner (2). The method may be used for producing liquid pig iron (17) or liquid steel precursor products (18) by a smelting reduction process in a smelting reduction unit (22).
