lime kiln diagram

A lime kiln is a kiln used for the calcination of limestone calcium carbonate to produce the form of lime called quicklime calcium oxideThe chemical equation for this reaction is CaCO 3 heat → CaO CO 2 This reaction takes place at 900 °C 1650 °F at which temperature the partial pressure of CO 2 is 1 atmosphere but a temperature around 1000 °C 1800 °F at which
