Kiln for limestone

Oct 21, 2021

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