摘要： A plant for the heat treatment of solids containing iron oxide. The plant includes a reactor including a fluidized bed reactor. The reactor includes a gas supply system disposed in the reactor, a stationary annular fluidized bed which at least partly surrounds the gas supply system, and a mixing chamber. The gas supply system is configured so that gas flowing through the gas supply system entrains solids from the stationary annular fluidized bed into the mixing chamber.

摘要： The present invention relates to a method and a plant for the heat treatment of solids containing iron oxide, in which fine-grained solids are heated to a temperature of 700 to 1150° C. in a fluidized bed reactor (8). To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through at least one gas supply tube (9) into a mixing chamber region (15) of the reactor (8), the gas supply tube (9) being at least partly surrounded by a stationary annular fluidized bed (12) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture and of the fluidizing gas for the annular fluidized bed (12) are adjusted such that the Particle-Froude-Numbers in the gas supply tube (9) are between 1 and 100, in the annular fluidized bed (12) between 0.02 and 2, and in the mixing chamber (15) between 0.3 and 30.

摘要： This invention relates to a process for reducing solids containing iron oxide, such as iron ore, in which fine-grained solids are heated and at least partly calcined in a pre-heating stage (2, 9). In a first fluidized-bed reactor (14) downstream of the preheating stage (2, 9), the solids are prereduced and reduced further in a second fluidized-bed reactor (16). Downstream of the second reactor (16) a briquetting stage (20) is provided, in which the solids are briquetted at a temperature above 500° C. To increase the energy efficiency of the process and improve the flowability of the solids in the briquetting stage (20), magnesite is added to the preheating stage (2, 9) together with the solids containing iron oxide, which magnesite is at least partly calcined in the preheating stage (2, 9) to obtain magnesium oxide. Furthermore, the invention relates to a corresponding plant.

摘要： A process of continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium. To ensure that the pressure between two regions can be reduced at low cost and with little maintenance effort when continuously conveying granular solids, a gaseous medium is injected into a tube through an upwardly directed nozzle at the point where the granular solids are conveyed through a descending line into an ascending line.

摘要： A plant for the heat treatment of solids containing titanium includes a fluidized bed reactor. The reactor includes at least one gas supply tube being at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is located, and a mixing chamber being located above the upper orifice region of the gas supply tube. The gas flowing through the gas supply tube entrains solids from the stationary annular fluidized bed into the mixing chamber when passing through the upper orifice region of the gas supply system. The plant further includes a solids separator downstream of the reactor. The solids separator includes a solids conduit leading to the annular fluidized bed of the reactor.
