Product Description:
Rotary kiln shell is a rotating inclined cylinder shape furnace, fired from one end to generate heat. Widely used during the production process of metals, construction materials, sponge iron, chemicals, cement, refractories, petroleum and gypsum, these Kiln Shells used various types of fuels for heating purpose.
Features:
High functionality
Accurate dimensions
Optimum performance
Application:
A rotary Kiln is a type of inclined cylindrical shaped rotating furnace which is used to heat solids to a temperature level when a chemical reaction is triggered through a wet or dry process. These kilns have a huge demand in the production of petroleum coke, refractories, sponge iron, alumina, gypsum, construction materials, chemicals, cement, metals, etc.
Working Principal:
The working principal of rotary kiln involves the firing of an inclined cylinder to generate heat from one end to all over its path. These Kilns generally fired directly and covered with refractory material to safeguard the steel shell to minimize loss by radiation and convey heat to the material.
All types of kilns are excellent heat exchangers that transfer heat through various modes like conduction, radiation and convection.
Different types of fuels which are used to ignite the kiln are petroleum coke, ground coal, gasses, fuel oils, and many more. Selection of fuel mostly depends upon the economics behind the consumption of a particular fuel. Transferring heat through gas radiation is an effective way to convey comparatively smaller amount of heat. Conduction to the charge and radiation from hot flame are reliable for hot bricks transfer.
Inclination of the kiln makes the processed material to move towards discharge point with every rotation taken by the entire body. From entry to discharge the form of material completely changes.
