发明名称 METHOD AND DEVICE FOR OPERATING A SMELTING REDUCTION PROCESS
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.
