lime, CaO, and produces lime mud, principally CaCO, as a by-product. The purpose of calcination is to convert the mud back into lime for reuse in the causticizing. The prime method used for calcination in the pulp industry is a rotary kiln. Conceptually,the lime kiln, which is a large cylindrical oven, can be divided into four process zones
This course covers the purpose of the lime kiln and the role of lime (CaO) in the chemical recovery process at a kraft pulp mill. Then it describes the components and sections of a rotary lime kiln, and the chemical reaction that takes place inside the kiln. Finally, it lists some common problems experienced in lime kilns.
in a rotary lime kiln, which is both a chemical reactor and heat transfer device. In this project, a control strategy was developed for the lime kilns in a Brazilian pulp mill in order to reduce the variability on calcination process and decrease the consumption of fuel. This control strategy

Chinese Climbing Kiln Diagram This is a diagram of the kind of kiln used by Chinese potters to obtain the temperatures necessary for stoneware and porcelain.
Typically, natural gas or fuel oil is be used to heat up the rotary kiln and then ignite the coal flame, but either may be used to fire the kiln up to full operating capacity if desired. The combustion system is designed with the flexibility to suit the following specific kiln firing applications:
Lime kilns are associated with every Kraft pulp mill and often used in steel mills. Since lime is manufactured from quarried limestone, lime plants are located near these deposits. The crushed raw material is fed to a rotary or vertical kiln where carbon dioxide is driven off to produce lime. The use of lime for any process depends on its
