What is Lime kiln?
[[Image:Lime Kiln 1.jpg|thumb|A preserved lime kiln in [[Burgess Park]], London]] A '''lime kiln''' is a [[kiln]] used to produce [[Calcium oxide|quicklime]] by the [[calcination]] of [[limestone]] ([[calcium carbonate]]). The [[chemical equation]] for this [[chemical reaction|reaction]] is: :[[Calcium carbonate|CaCO<sub>3</sub>]] + heat → [[Calcium oxide|CaO]] + [[Carbon dioxide|CO<sub>2</sub>]] Limestone is poured into one side of the kiln, it is then heated up with hot air and quicklime [Calcium Oxide] comes out the other end. Waste Gases come out of the top of the kiln. {{chem-stub}} [[Category:Chemistry]]
