摘要： Process and apparatus for producing liquid pig iron or primary steel products from iron-containing material in lump form in a fusion gasifier (1), in which, with lump coal and oxygen-containing gas being fed in, and with simultaneous formation of a reduction gas, the iron-containing material is fused, lump coal being fed to the fusion gasifier (1) from above and, together with the iron-containing material, forming a fixed bed (6) in the fusion gasifier (1) and thereby giving off its fraction of volatile hydrocarbons into the dome space (11) located above the fixed bed (6), and pulverized-fuel burners (15) being directed obliquely from above towards the surface of the fixed bed (6). The operation of the pulverized-fuel burners (15) is in this case controlled in such a way that the combustion of the carbon fraction of the carbon carriers in fine particle form takes place in a proportion of at least 40% to form CO2.

摘要： In a method for producing a hot CO- and H2-containing reducing gas serving for the reduction of fine-grained metal ore, in particular iron ore, the reducing gas is formed in a gasification zone by a gasification of carbon carriers, in particular coal, taking place under the supply of oxygen and subsequently is cooled down to a reducing-gas temperature favorable to the reduction process. In order to produce a thermodynamically more stable reducing gas, the reducing gas by the addition of H2O and/or CO2—in order to prevent the Boudouard and heterogeneous water-gas reaction and a resultant heating of the reducing gas—is converted to a reducing gas that is thermodynamically more stable at the reducing-gas temperature.

摘要： The invention relates to a process for producing pig iron or liquid primary steel products in a blast furnace, CO2 being substantially removed from at least a partial stream of a top gas emerging from a reduction shaft furnace (1), and this partial stream if appropriate being heated and being introduced into the blast furnace as reduction gas, and to a plant for carrying out this process, the top gas being introduced into the lower region of the blast-furnace shaft. This measure results in an improved energy balance and improved process management compared to the prior art.

摘要： A method for producing a hot CO- and H2-containing reducing gas utilized for the reduction of lumpy metal ore, in particular iron ore, which comprises forming the reducing gas in a gasification zone by the gasification of carbon carriers, in particular coal, taking place in the presence of a supply of oxygen and subsequently cooling the reducing gas down to a reducing-gas temperature favorable to the reduction process, wherein H2O and/or CO2 is added to a reducing gas which has been subjectged to a cooling operation that does not effect an addition of H2O/CO2 in order to prevent the Boudouard and heterogeneous water-gas reaction and a resultant heating of the reducing gas, wherein the reducing gas is converted to a reducing gas that is thermodynamically more stable at the reducing-gas temperature.
