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.

Clinkerization Cement Plant Optimization

The overall process of conversion from raw meal to clinker being endothermic demands a theoretical heat of about 380-420 kcal/kg-clinker. However, the rest of the specific heat consumption as tabulated above constitutes heat losses from preheater exhaust gases, clinker, cooler exhaust gases, preheater dust and radiation losses.

Towards net zero Low CO2 cement production

Mar 04, 2021 Due to the high demand for thermal energy and the nature of the clinker production process, electrical emissions from cement plants can often be sidelined. However, the CO 2 emissions associated with power generation still account for around 10-15% of the overall total. Minimising this is thus essential for producers seeking net-zero CO 2 ...
