Numerical Modelling of the Calcination Process in a …

Calcination is the process of calcium carbonate decomposition into calcium oxide (CaO) and carbon dioxide (CO2), typically occurring at a temperature around 850-900°C. As the calcination is an endothermic reaction (~1.7 MJ/kgCaCO3), fuel is combusted in the calciner. In the rotary kiln, the remaining calcination is completed and clinker is formed.

Clay Calcination

Like clinker production, clay calcination requires heat. But there is a huge different in scale: in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of clinker production.
