During the operation of the active lime rotary kiln, special attention shall be paid to the combustion of the kiln. The combustion of the kiln will affect the production efficiency and quality of the kiln. Therefore, the situation in the kiln shall be observed at all times during the operation to avoid sudden temperature drop of the kiln caused by various reasons. There are many reasons for the sudden cooling of lime kiln equipment. Let's learn about it.

1. Because the fuel particle size is too large, the combustion speed and temperature of the active lime rotary kiln fuel are related to the size of the fuel. If the fuel is too large, the combustion time will be longer and the combustion speed will be slower and slower. Therefore, attention should be paid to the selection of fuel during combustion to ensure the combustion effect of the fuel.

2. Unreasonable air supply will also cause sudden temperature drop. Combustion requires fuel, oxygen and fire. If there is fuel and fire but no oxygen, the combustion effect will be affected. Meanwhile, the supply of oxygen will also affect the combustion effect. Unreasonable local air supply will also cause problems in local combustion. Therefore, during the combustion of the kiln, it is necessary to ensure the stable operation of the whole kiln and the normal use of the temperature of the active lime rotary kiln.

3. The upward movement of the calcination zone of the kiln may also cause a sudden drop in the temperature of the kiln, which may be due to a corresponding reduction in the amount, a large air volume and an increase in excess oxygen. This is the upward movement of the calcination zone, and the upward movement of the calcination zone will make the fuel burn early in the upper part of the kiln. When the furnace burden falls to the calcination zone, the fuel has no fire power, the lime burning amount will naturally increase, the top temperature control is high, or the fuel entering the kiln is broken and burned prematurely.
