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 ...
