10.3.3 Cement manufacturing. 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

Apr 01, 2008 The sintering process applied was common for the production of both types of cement clinkers. The raw meals were shaped in small spheres, with a diameter of 2 cm, and dried at 110 C.Then, they were placed inside an oven at 500 C, the temperature was increased to 1000 C, at which the samples remained for 30 min, and, finally, the temperature was further increased to 1450 C

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker
