liimakone

Liimakone, also known as a lime kiln, is a type of industrial furnace used for the calcination of limestone to produce quicklime, which is then slaked to produce hydrated lime. The process involves heating limestone to high temperatures, typically between 900°C and 1200°C, in the presence of oxygen. This causes the limestone to decompose into calcium oxide (CaO), releasing carbon dioxide (CO2) as a byproduct.

Liimakone is a crucial component in the production of lime, which is used in various industries such as construction, agriculture, and water treatment. The lime produced is used for purposes like soil stabilization, pH adjustment, and as a coagulant in water treatment processes.

The design of a liimakone can vary, but it generally consists of a cylindrical or rectangular chamber with a refractory lining to withstand the high temperatures. The limestone is fed into the top of the kiln, and the hot gases produced during the calcination process are exhausted through a stack at the top. The lime produced is collected at the bottom of the kiln and can be further processed as needed.

Liimakone operation requires careful monitoring and control of temperature, fuel consumption, and gas emissions to ensure efficient and environmentally friendly production. Regular maintenance and inspection are also necessary to ensure the longevity and safety of the equipment.
