摘要： In a method and a device for operating a smelting reduction process, at least part of an export gas from a blast furnace or a reduction unit is thermally utilized in a gas turbine and the exhaust gas of this gas turbine is used in a waste heat steam generator to generate steam. The remaining part of the export gas is fed to a CO2 separation apparatus, the tail gas thereby obtained being fed to a waste heat steam generator and burned for additional steam generation. The combustible components of the tail gas are sent for thermal utilization in a steam generator, so that the overall energy balance of the thermal use of the export gas is improved. In addition, a further part of the export gas is qualitatively improved by the CO2 separation apparatus, so as to generate a high-quality reduction gas which can be supplied for metallurgical use.

摘要： A method for reducing iron-oxide-containing feedstocks by introducing a reducing gas into a high-pressure reducing unit (1) where the reducing gas is consumed by reducing iron-oxide-containing feedstocks and then the reducing gas is withdrawn as top gas from the high-pressure reducing unit (1). At least one subportion of the top gas is admixed to a feed gas as recycle gas (15). The reducing gas is generated by CO2 being separated off from the gas mixture obtained from the addition of the recycle gas (15) to the feed gas after one or more compression steps. The recycle gas (15) is added to the feed gas in at least two recycle gas substreams that are separated from one another with recycle gas substream pressures at various distances from the high-pressure reducing unit (1).

摘要： A method and a system for generating steam using the waste gases from plants for pig iron manufacture: waste gas removed as export gas (12) from the plant for pig iron manufacture is thermally utilized by combustion, and the waste gas from the combustion is fed to a heat-recovery steam generator (29). To utilize more energy from the export gas (12) for power generation, the export gas (12) is fed into a combustion chamber (23) located upstream of the heat-recovery steam generator (29), and after the combustion in the heat-recovery steam generator (29), heat is extracted from the export gas (12) without the export gas (12) passing through a gas turbine between combustion and heat-recovery steam generator. The pressure in the combustion chamber (23) and heat-recovery steam generator (29) are set above atmospheric pressure by means of a gas flow regulator (31) that is located downstream of the heat-recovery steam generator (29).
