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).

Abstract translation: 一种用于将细小颗粒材料（4）引入具有流化床（24）的流化床还原单元（1）中的方法，其中流化床（24）中的温度大于300℃，其中 细颗粒材料（4）通过燃烧器（2）直接引入流化床（24）和/或流化床（24）上方的自由空间（25）中。 该方法可以通过冶炼还原单元（22）中的熔融还原方法用于生产液体生铁（17）或液态钢前体产物（18）。

Abstract: A method for reducing metal oxide containing charge materials (1): reducing the metal oxide containing charge materials (1) in at least two fluidized bed units (RA,RE) by means of a reduction gas (2), wherein at least some of the resulting off-gas (3) is recycled and wherein the metal oxide containing charge materials (1) are conveyed into the fluidized bed unit RE by a propellant gas. Also, apparatus for carrying out the method according to the invention is disclosed.
