在这个过程中用于直接生产海绵铁颗粒与从块状铁矿石在直接还原单元（2）液态生铁的减少，在热状态下熔化气化器（1）被馈送到从细晶粒部分和粗颗粒部分直接还原单元海绵铁颗粒排出的分离，并且 熔融气化器被提供时，只有细颗粒部分。 分离发生在连接到所述空气分离器的直接还原装置的一个Austragsvorrichthung装置通过在逆流到海绵铁颗粒从冷却气体以预定的速度（7）流动。 该冷却气体混合到该气体混合物中的熔化气化器用于直接还原单元所产生的还原性气体，并和与该海绵铁此细粒部分夹带被传递到旋风分离器（5）和（6）。 本文将沉淀的固体，即，细颗粒部分和焦炭颗粒被引入到熔融气化器在流化床的水平。 从固体气体混合物释放的被用作在直接还原单元的还原气体。 其一部分预先支链，洗涤并压缩并用作冷却气体。 粗颗粒部分从所述空气分离器通入冷却或缓冲单元（4），然后从中排出。

@ In this process for the direct production of sponge iron particles and molten pig iron from lumpy iron ore in a direct reduction unit (2) is reduced and is supplied in the hot condition to a gasifier (1), the material discharged from the direct reduction unit sponge iron particles into a fine fraction and a coarse-grain fraction are separated and the melter only the fine-grain fraction is supplied. The separation takes place in a device connected to the Austragsvorrichthung of the direct reduction unit air separator (7), which is flowed through by a cooling gas at a predetermined speed in countercurrent flow to the sponge iron particles. This cooling gas is admixed to the reducing gas generated in the melter gasifier to the direct reduction unit, and this gas mixture and entrained with this fine-grained fraction of the sponge iron are fed to the cyclones (5) and (6). The precipitated solids herein, ie, the fine-grain fraction and coke particles are introduced into the melter gasifier in the amount of coal fluidized bed. Liberated from the solids gas mixture is used as a reducing gas in the direct reduction unit. A part thereof is previously branched off, washed and compressed and used as the cooling gas, the coarse grain fraction passes out of the wind sifter in a cooling or. Buffer unit (4) and is then discharged therefrom.
