    摘要: A plant for producing metal oxide from metal compounds includes a fluidized-bed reactor in which the metal compounds are heated by a combustion of a fuel to produce metal oxide. The fluidized-bed-reactor reactor includes at least one gas supply tube at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is disposed, and a mixing chamber disposed above an orifice region of the gas supply tube. A gas flowing through the gas supply tube entrains solids from the stationary annular fluidized bed when passing through the orifice region.

    摘要: The melting operation is carried out in an elongated horizontal reactor, in which sponge iron is charged onto the molten material in an intermediate region of the reactor, carbonaceous fuel and high-oxygen gases are blown into the molten material and slag and sponge iron are tapped at opposite ends of the reactor. To permit an economical melting of sponge iron having a large particle size range with the aid of virtually only solid carbonaceous fuels, the sponge iron is charged into the reactor in an intermediate region of 20 to 40% of the total length of the reactor, fine-grained carbonaceous fuel and high-oxygen gas are blown into the molten material from below in that region, the rates of oxygen and carbon are so controlled that a molten iron containing 1 to 3% carbon is produced, the remaining carbon contained in the molten material is reacted in the melt to produce CO, and the remaining energy required in the process is produced in that the CO and hydrogen are virtually completely burnt above the molten material as a result of a supply of oxygen-containing gases into the free space of the reactor.

    摘要: A process of gasifying fine-grained solid fuels for the production of a product gas that contains hydrogen, carbon oxides and methane comprises a treatment with steam, oxygen and/or carbon dioxide in two interconnected gasifying stages under a pressure in the range from 2 to 150 bars and at temperatures of 500.degree. to 1500.degree. C. In the first gasifying stage, the fuel is gasified in a circulating fluidized bed by a treatment with gasifying stage. The residual solids which become available in the first gasifying stage are fed to the second gasifying stage and are virtually completely gasified therein, except for residual ash, by a treatment with a gasifying agent which includes oxygen. At least one-half of the product gas from the second gasifying stage is fed to the first gasifying stage and used as fluidizing fluid therein.
