  • 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 which

  • Lime Production from Limestone Current Technology

    3) Lime Calcining (Conversion of limestone (CaCo3) to lime (CaO)) Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required.

  • Lime Production: Industry Profile

    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 CaCO 3 MgCO 3 + heat

    Quicklime is calcium oxide (CaO), which has varying particle size depending on the end use and high available calcium content. Quicklime is produced by burning or calcining limestone (calcium carbonate) in a kiln at 2000 degrees +/-. Quicklime is used primarily in flue gas treatment of sulphur emissions, water and wastewater treatment, soil amendment processing, well drilling applications
