    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 CaCO3 + heat → CaO + CO2This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which temperature the partial pressure of
