Specific matters of operation management of environmental protection lime kiln manufacturers

Specific matters for operation management of environmental protection lime kiln manufacturers:

1. After the production capacity of the environmental protection lime kiln is determined, the setting and adjustment of the coal ratio and air supply volume are directly related to the normal and stable thermal system of the shaft kiln, which is very important for the operation and management of the mixed mechanized lime shaft kiln. The adjustment of coal ratio after setting should be treated carefully, and should be determined after analyzing various factors. It varies with the fuel variety, and fine tune with the season and weather, and the adjustment range should not be too large. The air supply volume shall be adjusted according to the coal ratio to keep the calcination belt stable.

2. Quality management of raw materials, fuels and quicklime for environmental protection lime kiln

The quality management of raw materials and fuels is directly related to the calcination grade of lime, which is the prerequisite for product quality. The change in the quality of raw materials and fuels is also the main reason for the abnormal condition of the shaft kiln. The shaft kiln operator should focus most of his energy on the management of raw materials and fuels. On the premise of ensuring the supply, he should pay attention to the stable quality, classified management of raw materials and fuels, and graded management of particle size.

For the quality management of finished quicklime, it is necessary to conduct statistical analysis on its chemical composition, burned status, fly ash rate, activity, etc. in time, corresponding to the statistical analysis of raw materials and fuels, so as to timely understand and analyze the situation in the kiln and formulate reasonable operation adjustment principles.

3. Management of material level and ash discharge of environmental protection lime kiln

Material level stability is very important for stable operation of shaft kiln. If the material level is unstable or the shape is abnormal, the calcination zone will be unstable, and the air flow in the kiln will be abnormal, which will lead to abnormal kiln conditions and affect the output and quality of the shaft kiln.

The stability of the calcination zone can only be guaranteed if the ash discharge amount of the shaft kiln is consistent with the burning speed of the calcination zone of the shaft kiln. Too long ash discharge time and too large ash discharge amount will easily lead to the formation of funnel shape in the center of the shaft kiln and the suspension of the calcination belt. The mixing type shaft kiln must select the appropriate ash discharge time and amount to make the material layer fall evenly and flat, so as to ensure the stability of the calcination belt.
