Lime kiln
kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide)
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is:
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.
