Lime Kiln Operation by Luke Toft - A History of Mumbles

The burner's job also included removing the newly burnt 'quick lime' and general attention to kiln operation. Work on the lime kilns was arduous, hot and dusty. The gases leaving the top of a continuously operating kiln must have made manual charging an exhausting and unpleasant operation, although the top layer was cool.

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 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 (1650 °F; at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which ...
