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 whichPreparation of lime-rich sinter from waste limestone chips,preparing lime-rich agglomerates of higher basicity from limestone chips using coke breeze as a cheap energy source. Lime containing low silica content is used as a fluxing excess of 20 mm was taken to be the yield of the material1-6 for steel-making. This lime is obtained process. by calcination of marble grade limestone.Lime Production: Industry Profile,2.1.2 Calcination Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime
