Blast furnace coke should be sized to ensure good gas permeability in the shaft. An old rule of thumb states that the upper limit of the coke fraction shall be two times the lower limit. The lower limit of base coke is usually 40 mm, which gives the upper limit 80 mm. Small coke can be charged as separate charges and nut coke mixed with pellets.

In the modeling process, the petroleum coke discharging process was described by the solid viscous flow, the dynamic heat flux boundary condition was adopted to specify the …
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways: Drying

The calcination process of green petroleum coke in the vertical shaft furnace has been studied in the past years. A schematic of the process is shown in Fig.1. The process consists of three major equipment, including the VSF, the waste heat recovery boiler (WHRB) and the thermal deaerator (TD).
Vertical Shaft Kiln is used for the calcination of cement clinker, limestone, bauxite and other materials.The vertical kiln manufactured by ZK group has the advantages, such as modern design, new technology, environmental protection,energy saving, higher machanization and automaticity etc.
Twin shaft parallel flow regenerative kilns have two inter-connected, vertical shafts which are fired in sequence to achieve excellent energy efficiency. The stone size used by these kilns is usually between 90mm and 125mm. They are, on the whole, fuelled by natural gas and produce high reactivity and high purity quicklime.
