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

CaCO3 + heat → CaO + CO2

This reaction takes place at 900°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.

Limestone is deposited into a kiln which produces extreme heat using coal as the fuel. The limestone is thermally decomposed into lime and carbon dioxide. The lime collects at the bottom of the kiln in a solid lump while the carbon dioxide rises and is released through a small tube called the CO2 outlet. The reverse of this process can also be done in a lime kiln.

How can limestone be converted into calcium oxide?

By heating it. CaCO3 -> CaO + CO2 this was achieved traditionally in a lime kiln. The product, CaO was called quick lime as it reacted vigourously with water to form calcium hydroxde, which in turn was called slaked lime.

How do you get slaked lime from seashells?

the only way to get slaked lime is by burning the sea shells in a lime kiln then by adding cold water, this chemical reaction is by burning the carbon off from the calcium then replaced by oxygen atoms, this process will make the seashell lighter , when cold water is added this process will break down the seashell, then turn into hydrated lime.
