Vertical Shaft Lime Kiln - buildipedia. The alternate to premixing is feeding the kiln by alternate layers of fuel and limestone. However in the type of unmixed-fuel type vertical shaft kiln, the fuel is burnt in a separate box and hot flue gases so produced in the box enter the kiln through holes in the vertical shaft walls for burning the limestone in the kiln.
Vertical Shaft Kiln When simplicity, lower capital investment and easy maintenance are the main issues, Vertical Shaft Kiln is the right option for the refractory. Numerous fuels such as coke, coal, gas, oil, as well as other alternative fuels are combusted using different types of burner or charging systems.

Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
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 counter-current nature of the heating and the limited fuel and air mixing in vertical shaft kilns and the importance of this mixing to product quality.
