Lime kiln - Wikipedia - Know More
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 ....
