What is a lime kiln
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 CaCO3 + heat → CaO + CO2 This reaction can take place at anywhere above 840 °C (1,540 °F), but is generally considered to occur at 900 °C 展开A lime kiln is, in essence, a large oven used for heating limestone to create quicklime – a key ingredient in cement production, water treatment, and other important applications But how does it work? What are the different types of What is a Lime Kiln?
