The purpose of hanging the kiln skin of the rotary kiln incinerator is to extend the service life of the fire bricks, so that the rotary kiln shell is not damaged, and can reduce the heat loss to the outside, and improve the thermal efficiency. Its specific functions are as follows:
1. Protect the refractory bricks so that the refractory bricks are not directly exposed to high temperature and chemical attack.
2. Store thermal energy, reduce the heat loss from the kiln shell to the surrounding, and improve the thermal efficiency of the rotary kiln.
3. Fully heat transfer medium, when the kiln skin is exposed to the air, it will absorb heat by radiation or convection when it is in contact with high-temperature air, when the kiln skin is in contact with the material at the lower part, it will transfer heat to the raw material.
4. The surface of the kiln skin is rough, it can reduce the powder flow speed and prolong the reaction time of the material in the kiln.
