摘要:
An improved process for utilizing the residues of a thermal energy power plant washer in which limestone or lime residue is converted to gypsum and the substrate is recrystallized to alpha sulfate hemihydrate and is treated with water. The improvement comprises mixing the alpha sulfate hemihydrate with at least one additive. The additive is selected from the group consisting of flue ash from a coal combustion installation, waste washings or local tailings from coal recuperation, granulate of ash from coal combustion, slag from steel production, clacium sulfate from exhaust gas washers, and calcium sulfate dehydrate from exhaust gas washers.
