How Lime is Made
In general, the heat transfer from the fuel source to limestone can be divided into two stages: Calcining – the kiln fuel is burned in the preheated air from the cooling zone and, as the limestone moves down the kiln, the heat turns the limestone into quicklime and carbon dioxide (CO 2).
