Clinker Production - an overview | ScienceDirect Topics

Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.
