    why are lime kilns very large?

    Oct 15, 2019 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 + CO2. This reaction takes place at 900 C (1650 F; at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000 C (1800 F; at which temperature
