In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.

May 02, 2013· Calcination of Limestone . Calcination or calcining is a thermal treatment process to bring about a thermal decomposition. The process takes place below the melting point of the product. The name calcination is derived from the Latin word 'Calcinare' which mean to burn lime. Limestone is a naturally occurring mineral.
The calcination of limestone in normal shaft kilns is a complex process, since it is influenced by a variety of parameters. These influencing factors are: the operating variables such as energy input, throughput, type of fuel, air flow, the kiln parameters such as .
A process and apparatus for burning limestone to produce calcined lime in which limestone is burned continuously in a vertical kiln provided with a plurality of fuel injectors which permit pulsed introduction of fuel so as to ensure a lamellar flow of fuel through the kiln and a controlled release of heat.
However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing within a controlled ...
