[0002] A calcining kiln is a thermal equipment that performs heat treatment on raw materials at high temperatures to improve the performance of the raw materials. After calcination, most of the moisture and volatiles in the raw materials are removed, and the volume shrinks accordingly. The density, strength and conductivity are correspondingly improved. Calcination kilns generally use the volatiles overflowing from the raw materials themselves as fuel. When the fuel burns, air needs to be supplied from the outside of the kiln to assist combustion. At the same time, it is necessary to prevent oxidation losses caused by excessive supply of air. Therefore, the calcining kiln needs to control the intake volume of the supply air.
