Abstract
A method for processing hot, liquid slag includes the steps of: conveying the slag to be processed to an upper region of a granular material forming a fluidized bed that has a temperature below the solidification temperature of the slag; cooling the slag to a temperature below its solidification temperature while simultaneously forming granules; and maintaining the temperature of the fluidized bed at a temperature below the solidification temperature of the slag.
Claims54
