What are the effects of flame intensity on environmental protection lime kiln

The new environment-friendly lime kiln is a device used to produce lime. It adds environment-friendly functions on the basis of the lime kiln, making it meet the national green and pollution-free standards for lime production, so it is welcomed by the industry. We know that when calcining lime, the flame in the environment-friendly lime kiln needs to reach a certain intensity to make the quality better. What impact does the flame intensity have on the environment-friendly lime kiln?

The flame intensity includes the hardness, direction and luminous property of the flame. For an ideal flame, it is necessary to ensure that a high degree of heat exchange can be carried out in the whole flame length, and at the same time, no simple overheating is allowed. The environmental protection lime kiln requires a directional hard flame, that is, the flame in the kiln is hard and powerful when observed from the kiln head, and the flame tip extends forcefully towards the kiln tail, rather than being weak, floating or divergent in the kiln. The color of the flame, that is, the luminosity, and the red color of the flame will reduce the production and quality of the kiln.

During the calcination, the temperature of the flame can be judged according to the color of the flame, and the temperature of the materials in the calcination belt can be judged according to the color of the environmental protection lime kiln skin. When the flame color and kiln skin color are not clear, it indicates that the temperature of the firing zone is normal.

The environmental protection lime kiln has strict requirements on flame, especially the new dry process kiln, which requires rapid burning, so it requires high flame temperature, concentration, integrity, liveliness and strength. The ideal flame can generally be obtained by using multi-channel burners with good performance.

Now that we know the influence of flame intensity on lime kiln, how to effectively control the flame intensity of environment-friendly lime kiln? There are different flame intensities during the production of lime kiln. The flame intensity is related to the efficiency of the kiln. If the fire is not well controlled, the combustion quality of the kiln cannot be guaranteed. In the process of use, we should pay attention to the following aspects to control the furnace flame.

1. The flame intensity can be controlled by raw materials and air. The flame intensity can be judged by judging the hardness, direction and luminous property of the flame. If the model and operation of the furnace do not conform, the flame quality will also be inconsistent. We should ensure that the flame can achieve a high degree of heat exchange during use, and at the same time, it is not allowed to generate simple overheating The rotary kiln requires directional hard flame, that is, the flame in the kiln is hard and powerful when observed from the kiln head, and the flame tip extends forcefully towards the kiln tail, rather than being weak, floating or divergent in the kiln. The color of the flame, that is, the luminosity, and the red color of the flame will reduce the production and quality of the kiln.

2. During combustion, ensure that the furnace flame temperature and level are clear, and judge the flame control according to different quality.

3. In view of different requirements for different kilns, it is necessary to ensure that the flame temperature is high, centralized, complete, lively and powerful. The ideal flame can generally be obtained by using multi-channel burners with good performance.
