Calciner temperature control
-
The ventilation rate of the calciner also affects the outlet temperature of the calciner and the temperature of the lower part of the final cyclone. Even if the coal feed and material volume of the calciner remain unchanged, changes in the ventilation rate will also have an impact. When the ventilation rate is too large, the air velocity in the calciner is too fast, and the residence time of fuel and materials in the calciner is insufficient;

on the contrary, when the ventilation rate is too small, the gas supply is insufficient, and fuel combustion is also affected. In short, the fluctuation of the ventilation volume, the improper arrangement of the kiln air volume and the calciner air volume will affect the combustion of the calciner fuel, resulting in abnormal temperature at the outlet of the calciner and the temperature of the lower part of the final cyclone.[link text](
