APPARATUS AND METHOD FOR COOLING BULK MATERIALS

摘要

The invention relates to an apparatus and method for cooling bulk materials, the physical and chemical properties of which depend on the cooling medium, comprising: a. a base through which a cooling medium can flow and on which the bulk material is transported and cooled in the process, b. means for feeding a gaseous, non-oxidizing cooling medium, for example water vapour, c. means for the separate discharge of the heated, non-oxidizing cooling medium, d. a device for the thermal treatment of the discharged, heated, non-oxidizing cooling medium, e. means for recirculating the thermally treated, non-oxidizing cooling medium to the means for feeding the non-oxidizing cooling medium, f. means for feeding a gaseous, oxidizing cooling medium, for example air, g. means for the separate discharge of the heated, oxidizing cooling medium, h. and comprising a plurality of cooler sections and associated means for setting and regulating the cooling medium flows in order to optionally set either non-oxidizing cooling conditions or oxidizing cooling conditions in all the cooler sections or in individual cooler sections.
