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 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 CO 2 is 1

The process heats the limestone from ambient temperature to 900°C which is the point where the carbon dioxide is driven off leaving calcium oxide also known as quicklime Modern kilns are typically one of three designs single shaft annular or regenerative
