Temperature control method for active lime kiln
As an important raw material in industries such as steel and chemical, the quality of activated lime is closely related to the temperature control of kilns. Accurate temperature regulation can not only improve the activity of lime, but also reduce energy consumption and production costs. The following introduces several key temperature control methods for active lime kilns.
Fuel supply regulation
The fuel supply is a direct factor affecting the temperature of the kiln. By monitoring the temperature inside the kiln in real-time and comparing it with the preset temperature curve, the automatic control system is used to adjust the opening of the fuel valve and accurately control the amount of fuel entering. During the heating phase, gradually increase the fuel supply to ensure a steady rise in temperature; During the insulation phase, maintain a stable fuel supply to ensure temperature fluctuations are within the allowable range; Reduce fuel input during the cooling phase.
Air flow control
Air is the combustion aid for fuel combustion, and reasonable control of air flow is crucial for temperature regulation. Adjust the air volume of the blower according to the type of fuel and combustion condition to ensure full combustion of the fuel. Excessive air will take away heat and lower the temperature inside the kiln; Insufficient amount can lead to incomplete combustion, producing black smoke and lowering temperature. By using frequency conversion speed regulation technology to control the blower, precise adjustment of air flow can be achieved.
Material cutting control
The cutting speed and uniformity of materials can also affect the temperature distribution inside the kiln. Uniform and stable feeding can avoid local overheating or overcooling. By adjusting the speed of the feeding equipment and controlling the speed of material entering the kiln, the material is evenly distributed inside the kiln, ensuring the stability of the combustion process and maintaining the temperature balance inside the kiln.
