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.Clinker Production - Clinker Manufacturing | Cement,,Pure calcite in the kiln decomposes at around 650°C: 2 CaCO3 + SiO2 → Ca2SiO4 + 2 CO2. Reactive clay decomposition products and small amounts of alkali sulphate/chloride-melt draw the products together by surface tension and act as an ion transfer medium. Here, CO 2 is produced but no free lime (CaO) is formed.Cement clinker - Wikipedia,As of 2018 , cement production contributed about 8% of all carbon emissions worldwide, contributing substantially to global warming. Most of those emissions were produced in the clinker manufacturing process.
