摘要： There are described a method and an apparatus for controlling the level and/or the inventory in a fluidized bed in a fluidized-bed tank, wherein a stream of solids is withdrawn from the fluidized-bed tank via a downer, the stream of solids is fluidized at the bottom of the downer by supplying a conveying gas flow and is conveyed to the top through a riser branching off from the downer. The size of the stream of solids conveyed through the riser is varied by the variable supply of the conveying gas, wherein the level of the solids or the solids inventory in the solids tank is used as a control variable and the volume flow rate of the conveying gas is used as an actuating variable of a control circuit.

摘要： The present invention relates to the production of metal oxide from metal salts, in particular from aluminum hydroxide, wherein the metal salt is preheated in a first preheating stage, precalcined in a second preheating stage and calcined to metal oxide in a fluidized-bed reactor, and wherein the product obtained then is cooled in at least one suspension heat exchanger and subsequently in a multi- stage indirect cooler. To reduce the energy demand of a calcining plant, fluidizing air is supplied to the reactor with a temperature of up to 150 °C, and before entering the first preheating stage the metal salt is at least partly supplied to a hydrate drier in which it is indirectly heated with heat transfer medium from the first stage of the indirect cooler and dried.
