Abstract: A method for the heat treatment of solids containing iron oxide, in which fine-grained solids are heated to a temperature of about 630°C in a fluidized-bed reactor (1). To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through a supply tube (3) into a mixing chamber (7) of the reactor (1), the gas supply tube (3) being at least partly surrounded by a stationary annular fluidized bed (10) 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 bet (10) are adjusted such that the Particle-Froude-Numbers in the gas supply tube (3) are between 1 and 100, in the annular fluidized bed (10) between 0.02 and 2, and in the mixing chamber (7) between 0.3 and 30.

Abstract: This invention relates to a process for producing metal oxide from metal hydroxide, in which the preheated metal hydroxide is at least partly supplied via at least one pneumatic delivery conduit and via at least one downstream separating cyclone (8, 11) to a fluidized-bed reactor (12), where it is heated to a temperature of 650 to 1250°C by combustion of fuel, and metal oxide is produced. In a mixing vessel (19), the metal oxide is mixed with a partial stream of preheated metal hydroxide such that the preheated metal hydroxide is further heated and at least partly calcined. Then, the metal oxide is supplied from the mixing vessel (19) to at least one cooling stage (27, 28, 30, 31). The energy utilization of the process is increased in that the waste gas of the at least one separating cyclone (8, 11) is introduced into the mixing vessel (19) as conveying air such that the metal oxide from the mixing vessel (19) is pneumatically delivered into the at least one cooling stage or a de livery conduit (24) leading to the same. Furthermore, the invention relates to a corresponding plant.

Abstract: 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 pro vided, 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.

Abstract: This invention relates to a method and a plant for the heat treatment of solids, in particular for reducing solids containing iron oxide, in a fluidized-bed reactor (5, 30). For fluidizing the solids, fluidizing gas is introduced into the fluidized-bed reactor (5, 30) via distributor grates (7, 32). Between a solids feed pipe (37) and a solids discharge pipe (38) of the fluidized-bed reactor (5, 30), the solids pass through multiple chambers (8, 34) each with a distributor grate (7, 32), which are at least partly separated from each other by weirs (6, 33). The pressure of the fluidizing gas introduced into the individual chambers through the distributor grates (7, 32), which are offset with respect to each other in vertical direction, substantially is the same. The delivery of the solids from the solids feed inlet 15 (37) to the solids discharge outlet (38) is promoted by the inclination of the fluidized-bed reactor (5, 30) with respect to the horizontal.

Abstract: The present invention relates to a method and a plant for producing low temperature coke, in which granular coal and possibly further solids are heated to a temperature of 700 to 1050°C in a fluidized-bed reactor (2) by means of an oxygen-containing gas. 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 (3) into a mixing chamber region (8) of the reactor (2), the gas supply tube (3) being at least partly surrounded by a stationary annular fluidized bed (6) 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 (6) are adjusted such that the Particle-Froude-Numbers in the gas supply tube (3) are between 1 and 100, in the annular fluidized bed (6) between 0.02 and 2 and in the mixing chamber (8) between 0.3 and 30.

Abstract: 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.
