    A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate).The chemical equation for this reaction is:. CaCO 3 + heat → CaO + CO 2. Limestone is poured into one side of the kiln, it is then heated up with hot air and quicklime [Calcium Oxide] comes out the other end.
