Method for calcining delayed coke (Patent) OSTI.GOV

Abstract. Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.

Shaft Kilns - Lime Vertical Shaft Kiln Exporter from Vadodara

The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.
