    摘要： A process for producing metal oxide from a metal salt includes supplying a first part of the metal salt to a hydrate drier so as to indirectly heat the first part of the metal salt in the hydrate drier using a heat transfer medium from a first stage of a multi-stage indirect cooler so as to dry the first part of the metal salt in the hydrate drier and so as to control a waste gas temperature of the process. A second part of the metal salt is guided as a partial stream past the hydrate drier. The metal salt is preheated in a first preheating stage and precalcined in a second preheating stage. The metal salt and a fluidizing gas having a temperature of 150° C. or less are supplied to a fluidized bed reactor so as to calcine the metal salt to form a metal oxide product. The metal oxide product is cooled in at least one suspension heat exchanger and then in the multi-stage indirect cooler.

    摘要： An apparatus for the treatment of at least one of solids and gases includes a fluidized-bed reactor configured to fluidize the solids using fluidizing gas and to at least one of thermally and chemically treat the solids. A centrifugal separator is configured to separate the fluidizing gas and the solids from each other. A transfer duct connects the fluidized-bed reactor and centrifugal separator to each other. The transfer duct has a trapezoidal cross-section in a vertical direction and in a horizontal direction. The transfer duct branches off from the fluidized bed reactor with a cross-section having a horizontal dimension that is greater than a vertical dimension. The cross-section of the transfer duct expands downwards in the vertical direction from the fluidized-bed reactor to the centrifugal separator. The cross-section of the transfer duct tapers in the horizontal direction from the fluidized-bed reactor towards the centrifugal separator.
