Causes and Preventive Measures of Coke Brick Phenomenon in Cement Rotary Kiln Equipment

The rotary kiln is a high-temperature calcination equipment, and various conditions may occur during the calcination production process. If you can't grasp and understand all kinds of situations, it is easy to be confused after the situation, and you may not even know what is going on and will not deal with it. This is very dangerous for the use of the rotary kiln and the safety of the operator.

The rotary kiln is a high-temperature calcination equipment, and various conditions may occur during the calcination production process. If you can't grasp and understand all kinds of situations, it is easy to be confused after the situation, and you may not even know what is going on and will not deal with it. This is very dangerous for the use of the rotary kiln and the safety of the operator.

In the long-term calcination process of cement rotary kiln equipment, the phenomenon of coke brick sometimes occurs, and thus the normal calcination process of the equipment is affected. In order to prevent such failures, we should first familiarize ourselves with the causes and preventive measures of causing the phenomenon of coke bricks. In this article, ZK CORP will discuss with you the causes and preventive measures of the phenomenon of coke bricks in cement rotary kiln equipment.

First, the reasons for the phenomenon of causing bricks in cement rotary kiln equipment are as follows:

1. When burning bricks in the kiln, the air in the middle of the billet is insufficient. The kiln worker is inadvertently watching the fire, the burning belt is elongated, the fire is too large, and the body softens at high temperature.

2. The amount of fuel in the kiln of the cement rotary kiln equipment is too large.

3. The damper is used improperly, and the pumping force is too large, so that the combustion intensity of the internal fuel is too large, the temperature rises too fast, and the temperature in the kiln exceeds the allowable firing temperature of the blank.

4. The form of the fire eye batch is unreasonable, and the proportion of the upper and lower tribal coal is improper.

Second, the cement rotary kiln equipment to avoid the phenomenon of coke bricks can start from the following three points

1.First of all, before the failure occurs, it is mainly based on prevention, and closely monitor the pre-tropical fire of the cement rotary kiln equipment. When it is found that the pre-tropical fire has a tendency to develop into a fire, it is necessary to extract high-temperature gas from the back of the pre-tropical zone in advance. When the harbinger of the fire is obvious, the residual heat brake of the firing zone can also be lifted up, and the fire can be controlled by arson in advance to control the speed of the fire.

2. Regardless of the use of residual heat utilization system, reduce the height of each damper, delay the speed of the fire head, are conducive to control the fire. When the firing zone is too hot, lift the residual heat brakes at the front and rear of the fire to disperse the firepower. If the heat brake at the fire is raised, not only can the firepower be distracted, but the firepower will be concentrated and the fire will be burnt.

3. When the cement rotary kiln equipment is fired with a large bottom, the first step is to lower the remote gate and the near gate. In addition to the reheating brake, the air volume must be increased to accelerate the cooling. In addition, you can carefully lift the damper of the insulation belt and pull out the high temperature air at the bottom. However, it should be noted that the Ha damper at the fire cannot be mentioned, because it can not only disperse the firepower, but instead concentrates the firepower, and there will be coke bricks and even a crusting or kiln accident.

The above is the reason why ZK CORP technicians share the phenomenon of coke bricks in cement rotary kiln equipment and the prevention measures, I hope to be helpful to you. For more information on rotary kiln, please consult our online customer service.
