摘要： A high organic concurrent decoating kiln includes a low-oxygen zone and a high-oxygen zone. The disclosed kiln allows a gas low in free oxygen to be used in the initial stages of decoating, while a gas higher in free oxygen can be used in the final stages. The total amount of free oxygen used throughout the kiln, in particular at the upstream portion of the kiln, is kept low. Exhaust gas can be recirculated for use in a burner-fired chamber that provides the initial low-oxygen gas to the kiln.

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 and a configuration recover thermal energy in a thermal treatment of cold-rolled steel strip in an annealing furnace. The steel strip is heated up in a protective gas atmosphere to a temperature above the recrystallization temperature, and is subjected in a first, slow cooling phase and a second, fast cooling phase to a protective gas. The temperature of the protective gas is reduced during the first phase down to an intermediate temperature and in the second phase from the intermediate temperature to a final temperature. A first heat exchanger transfers the thermal energy of the protective gas by an oil circuit and a second heat exchanger to a working medium, and which evaporates and is fed to a steam motor, which converts the thermal energy contained in the working medium into energy.

The installation further has a charging element, which has been filled with scrap metal intended for the melting furnace and can be moved in a movement direction into the charging region where it can be emptied and then moved again, in the empty state, against the movement direction out of the charging region. The charging region is enclosed by a hood such that the charging region, including the charging element which has been placed in the charging region, is closed at the top and on the sides. The hood has at least one upper extraction opening through which the waste gases and dust developing in the hood can be extracted out of the hood.
