PROCESS FOR THE PRODUCTION OF DRY FLUE GAS GYPSUM

摘要

Flue gas gypsum having a free water content of 4% by weight and thereabove is dried in direct contact with a partial stream withdrawn from the primary stream of a dry-dedusted flue gas and is separated from this partial stream, which latter is then fed to the intake side or to the delivery side of the booster blower arranged upstream of the flue gas desulfuration device, and the finely particulate flue gas gypsum is conducted from the drying device into the flue gas desulfurizing device.
