Calcination - Burning Limestone | Unity Lime

Calcination – Burning Limestone. Quarried stone is crushed and transported to a lime kiln. The lime burning process within the kilns requires enough heat to be transferred to the limestone in order to decompose the calcium and magnesium carbonates. Heat transfer for lime burning can be divided into three main stages:

Modeling of Limestone Calcination Using Joule Heating

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO 2 in the gas above the solid surface is less than the decomposition pressure of the CaCO 3.As the reaction is endothermic, the conventional process for calcination uses coal firing in rotary kiln with limestone feed to get the desired temperatures.

Calcination Reactions Limestone Calcination. During the calcination of limestone, it follows a decomposition chemical reaction. CaCO 3 → CaO + CO 2 (g). We can take the standard Gibbs free energy of reaction as ΔG°r = 177,100 − 158 T (J/mol). Meanwhile, the standard free energy of the reaction = 0 when the temperature is set at 1121 K, or 848 °C.
