    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: In a method for the production of molten metal, oxygen, a reducing agent and iron reduced in a reduction reactor are introduced into a melt gasifier, the reducing agent is gasified with oxygen and reduced iron is melted by means of the heat which occurs, the cupola gas being used as at least a fraction of the reduction gas. Reacted top gas is drawn off from the reduction reactor.For increased efficiency in terms of energy and raw materials, there is in this case provision for at least part of the heat energy of the top gas and/or of the fraction of the reduction gas which is provided for use as cooling gas and as excess gas to be utilized for the indirect heating of at least one further gas used in the method.For this purpose, at least one heat exchanger in a line for top gas and/or the fraction of the reduction gas which is provided for use as cooling gas and as excess gas is provided, at least one further gas used in the method flowing through said heat exchanger.

    摘要: Process gas purification device (2) for a melt reduction system (1) comprising at least one reduction reactor (3) and a melting gasification reactor (4), a first line system (5) for discharging a furnace gas (6) from the reduction reactor (3) and a second line system (7) for discharging a generator gas (8) from the melting gasification reactor (4) wherein both line systems (5,7) lead to a respective wet scrubbing system (11, 12). The furnace gas or generator gas flow can be throttled preferably by way of a control element (41) that varies a control gap (40) and the scrubber or cooling liquid (49) can be collected and drained. The first wet scrubber system (11) of the first line system (5) for routing the furnace gas (6) and the second Venturi scrubber system (12) of the second line system (7) for routing the generator gas (8) both discharge into a common mist elimination device (14).
