    摘要: A process and an apparatus for producing liquid pig iron or liquid primary steel products from charge materials formed by iron ores and additions. The charge materials are subjected to a further reduction in a reducing zone (1) and are then fed to a smelting zone or a smelting unit (2), in particular a fusion gasifier, for smelting with the addition of carbon carriers and oxygen-containing gas to form a fixed bed. A CO- and H2-containing reduction gas is formed, which gas is introduced into the reducing zone converted there and drawn off as top gas. The hot top gas, laden with solid matter, after separation of the solids, is subjected at least to a dry coarse separation and at least parts of the hot solids segregated by the separation are returned into the smelting zone or the smelting unit (2) or the reducing unit (1). In addition, the top gas is treated in a further fine separation stage (13A).

    摘要: The invention relates to a method and a device for the coarse separation of solid particles from solid-laden gases. The invention further relates to a method for treating particulate feed materials by means of treatment gases in a reactor, particularly in a fluidization zone at an increased temperature. Due to a blind hole-like line extension, it is possible to separate solid particles from a solid-laden gas.

    摘要: A description is given of a method of optimizing the design and operation of a reduction process for iron-containing charge materials (3), preferably in lump form, in a reduction shaft (1) to which reduction gas (9) is fed, for example from a fusion gasifier (6), with a reduced product (13), for example iron sponge, being taken from the reduction shaft (1) for the production of liquid pig iron or liquid primary steel products, in which method the reduction process is described by means of a mathematical-physical-chemical process model, the reduction shaft (1) is modelled multi-dimensionally, in particular three-dimensionally, and the process model is numerically evaluated and the results of the evaluation, obtained as multi-dimensional, in particular spatial, distributions of physical or chemical variables, are taken into account for the reduction process. This allows the reduction process to be quantitatively assessed in the entire reduction shaft and, as a result, the reduction process can be optimized.
