PROCESS FOR DRYING MOIST GYPSUM, ESPECIALLY GYPSUM FROM A WET FLUE GAS DESULPHURISATION PLANT, AND DEVICE FOR CARRYING OUT THE PROCESS

摘要

1. A process for drying moist gypsum, in particular gypsum from a wet-chemical flue-gas desulphurisation unit, by means of flue gas from a furnace installation, in particular of a coal-fired power station, wherein heat is exchanged between the air, which at least in part is fed as combustion air to the furnace installation, and the flue gas issuing from the furnace installation, characterised in that the moist gypsum is dried with hot drying air which is heated by heat exchange with the flue gas of the furnace installation.
