Lime kiln - Wikipedia

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which ...

Calcination - Wikipedia

In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is CaCO 3 (s) → CaO(s) + CO 2 (g). Today, this reaction largely occurs in a cement kiln.. The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K ...
