vertical shaft kiln for coke calcination

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.

Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB's).
