Several factors affecting the heat consumption of rotary kiln clinker

In actual production, the reactions and changes of materials during the process of calcining clinker are accompanied by huge heat losses. The following summarizes for you several factors that affect the heat consumption of rotary kiln clinker.

1. Differences in rotary kiln production methods. Depending on the production method, the amount of heat consumed in the calcining of the raw material is different. Generally, the heat consumption of the wet method will be higher than that of the dry method.

2. Loss of waste heat from the rotary kiln exhaust gas. Because a large amount of heat is lost when clinker is cooled, the waste heat can be recycled. What has been realized is that it can be used as combustion-supporting air and waste heat to generate electricity, thereby effectively improving heat transfer efficiency and reducing heat energy loss.

3. Characteristic factors of raw material in rotary kiln. Because raw materials with finer particles are easy to burn in the rotary kiln, the heat consumption will be greatly reduced.

4. Incomplete combustion of rotary kiln fuel leads to increased heat consumption. There are many factors that cause incomplete combustion of fuel during the normal operation of rotary kiln equipment, so the occurrence of this situation will consume a lot of heat, so the heat consumption of clinker also increases accordingly.

5. The heat dissipation factor of the rotary kiln body. In general, the better the insulation effect of the kiln lining, the less heat consumption. From the above summary, we know that heat consumption is inevitable in the normal operation of the rotary kiln, which not only affects its efficient production, but also violates the production concept of energy conservation and environmental protection. Therefore, reducing the heat consumption of the rotary kiln has become a common responsibility of everyone.
