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 . CaCO 3 + heat CaO + CO 2. This reaction takes place at 900 #176;C (1,650 #176;F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 #176;C (1800 #176;F; at which
