VORRICHTUNG UND VERFAHREN ZUR THERMISCHEN BEHANDLUNG MINERALISCHER FESTSTOFFE
An apparatus for thermally treating mineral solids includes a preheater, a separating apparatus arranged at an outlet of an entrained flow reactor, and a thermal treatment zone at an outlet of a gas stream of the separating apparatus, with an outlet of the treatment zone being connected to an inlet of the preheater for the gas stream. A process may involve preheating a mineral material, thermally treating the mineral material in an entrained flow reactor in a reducing atmosphere for reducing coloring metal compounds, separating a solid/gas mixture from the entrained flow reactor in a separating apparatus, oxidizing reducing constituents of a gas from the separating apparatus in a thermal treatment zone between the separating apparatus and the preheater via supplied oxygen, and supplying gas emerging from the thermal treatment zone to the preheater and thereby utilizing thermal energy recovered in the thermal treatment zone by transfer to mineral material
