    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 can take place at anywhere above 840°C (1544°F), but is generally considered to occur at 900°C(1655°F) (at which temperature the partial pressure of CO 2 is 1 ...

    Rotary kilns generally require more heat than shaft kilns. The heat use tends to increase as the degree of burning increases. The net heat use varies between 3 600 and 7 500 MJ/Mg of lime for calcium quicklime and light- and hard-burned dolomite, and between 6 500 and 10 500 MJ/Mg of lime for dead-burned dolomite (European Commission, 2001).
