  • 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 °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 whichprocess (carbonation) vessel, and then decomposed in a separate (cracker) vessel at a higher temperature The regenerated lime would then be returned to the carbonator [2,3] This process can be economical because the raw material is limestone and circulating fluidised beds are suitable process vessels This review will be restrictedReview Review—calcination and carbonation of limestone
