摘要： A method and a device for balancing out amount fluctuations while simultaneously increasing the temperature of an export gas (2) used in a reduction process (1). A first partial amount (3) of a recycling gas (4) is cooled in at least one recycling-gas cooler (5) to form a cold recycling gas (6) and the cold recycling gas (6) is fed to the export gas (2) in a pressure-controlled and/or amount-controlled manner in order to balance out amount fluctuations of the export gas (2). A second partial amount of the recycling gas (4) is fed to the export gas (2) as hot recycling gas (7) having a higher temperature than the cold recycling gas (6). Then an export gas mixture (8) of the cold recycling gas (6) and the hot recycling gas (7) is introduced into the reduction process (1), wherein the temperature of the export gas mixture (8) is higher than the temperature of the export gas (2). The temperature of the export gas (2) or of the export gas mixture (8) is set in such a way that temperature is higher than the dew point or dew point temperature of the export gas mixture.

摘要： A method for producing steel in which iron ore is reduced with hydrogen and the resulting intermediate product of reduced iron ore and possibly accompanying substances is subjected to further metallurgical processing; the hydrogen is produced through electrolysis of water; the electrical energy required for the electrolysis is regenerative energy from hydroelectric and/or wind and/or photovoltaic sources or other regenerative forms of energy and the hydrogen and/or the intermediate product is produced regardless of the current demand, whenever enough regeneratively produced electrical energy is available; and unneeded intermediate product is stored until there is demand or it is used so that the regenerative energy that is stored therein is also stored and a method for storing discontinuously produced energy in which the discontinuously produced energy, when it is present or after its production, is conveyed into a process in which a storable intermediate product is produced from a source material and the storable intermediate product is stored until it is required and retrieved for the production of an end product.

摘要： A raw gas collection system (15) for collecting raw gas from a plurality of aluminum smelting pots (4) is equipped with a plurality of branch ducts (16, 16a-d). Each branch duct (16, 16a-d) is arranged to channel a respective branch flow (32, 32a-b) of raw gas from an aluminum smelting pot (4) to a collecting duct (20a), which is common to and shared by branch ducts (16, 16a-d). Several of the branch ducts (16, 16a-d) are equipped with a combined heat transfer and flow resistance generating element (17) to remove heat from the respective branch flow (32, 32a-b) of raw gas and to balance the flow of raw gas in the raw gas collecting system (15). The combined heat transfer and flow resistance generating elements (17) reduce the need for adjusting the respective branch duct (16, 16a-d) flow volumes using dampers, thereby reducing the power required to transport the raw gas through the system.

摘要： In a blast furnace plant, at least three regenerative heaters are cyclically operated on blast and on gas: while a regenerative heater is operated on gas, hot flue gas is produced and caused to flow through the regenerative heater so as to heat the heat storage elements; and while a regenerative heater is operated on blast, process gas, i.e. a CO-rich fraction of the top gas, is blown through the regenerative heater so that the process gas takes up heat from the heat storage elements, such that during a changeover of a regenerative heater from on-blast to on-gas operation, the regenerative heater is purged from process gas using flue gas collected after having flown through at least one of the regenerative heaters.

摘要： Methods for carrying out high temperature reactions such as biomass pyrolysis or gasification using solar energy. The biomass particles are rapidly heated in a solar thermal entrainment reactor. The residence time of the particles in the reactor can be 5 seconds or less. The biomass particles may be directly or indirectly heated depending on the reactor design. Metal oxide particles can be fed into the reactor concurrently with the biomass particles, allowing carbothermic reduction of the metal oxide particles by biomass pyrolysis products. The reduced metal oxide particles can be reacted with steam to produce hydrogen in a subsequent process step.

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.
