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 .
China and Japan In Japan, they normally use the manufacturer data and the code does not provide stress value In UK, the Piklkington glass recommendation is used since BS does not provide this value In Canada , they give detailed stress value Whilst the charts in USA are similar to the Canadian one, they are based on the same stress
1117 Lime Manufacturing 11171 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing To be classified as limestone, the rock must contain at least 50 percent calcium carbonate
