Working Principle of a Rotary Furnace and Industrial Applications
A rotary furnace is essentially a rotating cylinder around its axis, allowing heat treatments. It is slightly tilted to enable the movement of charge material from one end to the other, thus promoting mixing and equalizing in heating. The heat required for the operation is commonly supplied by hot gases blowing in the counter-current direction to the material flow.
Key Components
Furnace Body: This is made of steel, and the length of the barrel may vary depending on the application.
Furnace Lining: The furnace is insulated with refractory materials such as bricks or cement from high temperatures and corrosion.
Drive Gear: This is responsible for the rotation of the furnace; it is normally fitted with a variable speed drive.
Heat Source: The heat source can either be gas or electric, and heat is supplied by conduction, convection, or radiation.
Industrial Applications
The rotary furnaces find applications in various industrial processes, which include:
Oxidation: This procedure involves the reduction of electrons in the sample.
Calcinations: It is the thermal decomposition of materials.
These are very important processes in various industries, for example, metallurgy, waste processing, and chemical manufacture.
