Cement clinker production by utilizing waste heat of molten steel slag

Abstract

The future of energy-consuming steel-making industry strongly depends on the improvement of eco-efficiency; that is, more products except a steel by less input energy. This paper describes a feasible study of symbiotic steelworks with anew heat recovery concept using endothermic chemical reactions. The results revealed a merit of heat recovery of molten slag by using themmal decomposition of limestone for producing a cement clinker from viewpoints of reducing energy consumption and carbon dioxide emission.
