VERTICAL STEEL KILN PLANT
The process of lime production involves the heating of limestone above its dissociation temperature. The process of heating is called calcinations, which is highly endothermic. The dissociation temperature of CaCO3 (calcite) is about 9000 C. During limestone dissociation, the reaction is facilitated by the continuous removal of CO2 evolved during Calcination. The chemical reaction to produce lime is represented below: CaCO3 (solid) + heat ↔ CaO (solid) + CO2 (gas)
The vertical steel lime kilns have been shown to posses a lot of potentials in the lime industry In view of the need to set up more small/medium scale chemical plans to meet with the local needs of chemical products like lime. This type of kiln made by outside body steel and from inside fire bricks Kilns employ variety of fuels namely:- Wood, pet coal, The type of fuel to be used will depend on the economics and local legal requirements.
