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 CaCO3 + heat → CaO + CO2This reaction can take place at anywhere above 840°C (1544°F), but is generally considered to occur at 900°C(1655°F) (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature ar
