  • Lime Burning Operation Heat Energy Requirements

    Nov 03, 2020 · It is considered good practice to allow a small amount of unburned limestone in the interior of the quicklime pebble. This results in a continuous evolution of carbon dioxide from the limestone. This keeps the lime porous during calcination and tends to prevent overheating of the lime as the carbon dioxide gas is evolved.
