“The main components of a calcination plant include a green coke delivery and storage area, a vertical shaft kiln/calciner, a calcined coke storage-silo, calcined coke crushing, screening and bagging facility and a storage area for the products of the calcination process.” The coke calcining process is a time-temperature function conducted in an oxygen deficient atmosphere. The process is
Chapter 1 Shaft kilns LTV
Shaft kilns and cupola furnaces are used for the mass conversion and melting of granular and coarse materials. The material is transported through the vertical shaft by gravity. The hot gas flows in a counter current to the material. Typical processes are summarized in Table 1-1. For calcination processes mainly the name shaft kiln is used and for melting processes mainly the name cupola

Lime kiln Wikipedia
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which
