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 + CO2This 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.
In a lime kiln calcium carbonate is heated to form quick lime and carbon dioxide. CaCO3 -> CaO + CO2
so that limestone can decompose to form CO2 and CaO
Kiln
There is raccu kiln, electrical kiln, and gas kiln.
As a thumb rule the kiln inclination is 3.5% of its length.
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
Lime Kiln Middle School was created in 1999.

Coke is used in a lime kiln as a fuel source to provide the high temperatures needed for the chemical reactions that convert limestone into quicklime. Coke is preferred due to its high carbon content and low impurities, making it an efficient and reliable fuel for the lime kiln process.
Calcium carbonate, limestone, is baked in a kiln to produce quicklime, calcium oxide.
In a lime kiln, carbon dioxide is created as a byproduct of the chemical reaction that occurs when limestone (calcium carbonate) is heated to high temperatures to produce quicklime (calcium oxide). The carbon dioxide is released as a gas during this process, leaving behind the calcium oxide.

Lime kilns need to be large to allow for sufficient heat transfer and chemical reactions within the kiln. The large size also allows for greater production capacity and efficiency in the production of lime from limestone. Additionally, the large size helps to ensure uniform heating and proper circulation of air and gases for optimal lime production.
The process is called calcination or lime-burning. This mined from the Wikipedia article on calcium oxide. A link is provided.
The stream of air carries away the carbon dioxide formed in the decomposition. If it were allowed to build up in the kiln, it would start to react again with the newly formed calcium oxide, and an equilibrium would be set up instead of the reaction's going to completion.
Limestone, which contains calcium carbonate, is heated in a kiln to produce lime. This lime is a key ingredient in the production of cement when mixed with other materials such as sand and water.
