Vertical shaft kilns use similar technology and processes but are less efficient. However, by their nature, vertical shaft kilns are more challenged by hydrogen fuel than parallel flow regenerating kilns, given countercurrent nature of the heating and the limited fuel and air mixing in vertical shaft kilns and the importance of this mixing to product quality.
Shaft Kiln – Issojet Burner Pvt Ltd
Shaft kiln In a shaft kiln, raw material moves counter flow to hot gas in the shaft. This gives shaft kilns the lowest fuel consumption of any type of kiln. The shaft refers to a vertical vessel where the firing takes place. Because of the weight of the

Advantages and disadvantages of Vertical Shaft Lime Kiln
Abstract. The calcination principle of composite firing shaft kiln is: mix the solid fuel (coke or anthracite) with qualified stone evenly, use rotary discharging device equipped on kiln roof to discharge the mixture into the kiln, then under its own gravity the mixture proceeds through preheating area, calcining area, cooling area, and finally calcined into qualified finished lime product.

Clinkerization
The conversion taking place in kiln system as raw meal is heated gradually to clinkerization temperature (1450 0 C) as shown below in table 1. Kiln system has seen a sea of development since 1950s to till date, from vertical shaft kilns to modern precalciner kiln. Capacity has increased from as low as 50 tpd to as high as 12000 tpd from kiln.
Twin Shaft Regenerative (TSR) Kilns | MEKITCO
Twin Shaft Regenerative (TSR) Kilns: The Twin Shaft Regenerative (TSR) kiln is a doubleshaft vertical kiln which utilizes the regenerative process for lime calcination.
