Abstract

PURPOSE:To provide the subject device where high-temperature liquefied slags are introduced in a rotary kiln together with granulated slags which have been precooled, said liquefied slags are granulated by the charging of cooling air, and heated air is taken out into an exhaust gas boiler, thereby recovering a large quantity of heat energy.
