Cement Kilns: Clinker Thermochemistry

A current of hot air, with a CO 2 partial pressure of 40 Pa, can remove carbon dioxide at 536°C, but kiln gases contain perhaps 35% CO 2, and would decompose pure calcite only above 829°C. In reality, in a kiln burning a normal cement rawmix, decomposition begins at around 650°C. This, put simply, is because the clay components (or their ...

Cement Kilns: Clinker Thermochemistry

In isolation, feldspars do not decompose at such a low temperature, but in the conditions of the cement kiln, alkalis become detached and will usually react immediately with the acid gases of the kiln atmosphere. An equation describing this might be: KAlSi 3 O 8 (orthoclase) + 0.5 SO 2 + 0.25 O 2 → 3 SiO 2 + 0.5 Al 2 O 3 + 0.5 K 2 SO 4
