Rotary kiln heat transfer processes and close

Article source：

Rotary kiln heat transfer processes and the relationship is a complex issue. Heat capacity of the kiln after alteration even further reduced than in the past, it is not

due to reduction in the kiln burning zone and forced to lower the load is too large, but because the calcination require lower heat consumption and lower exhaust

gas temperature. If the kiln has more heat transfer area, it is possible without increasing the heat consumption on the basis of increased production. Looking

specifications must be further changes in the kiln kiln after each thermal element changes. Kiln based on the measured material in the process the results of

sampling and analysis, while the kiln take a long 10m, and the material decomposition curves are almost coincident. Take a long future in the kiln, kiln skin, flame

position, raw material shadow and nothing significant changes. Therefore, it is considered to take a long kiln kiln after the cooling zone, firing zone and

decomposition is substantially no change in position of the belt. Major changes occur in the low temperature portion of the kiln. Prominent is the preheating zone

extends to the original 5.48m 19.92m, more than the entire length of the kiln bigger changes. This phenomenon raises a question that is on the same diameter kilns,

each with the percentage in the kiln is not the same; when other conditions are the same, kiln dried with a preheating zone and the proportion will be even greater .

The driving force is the temperature difference between the heat transfer, so you will need the gas, the temperature and heat transfer material combined analysis of

the relationship between heat and kiln. The above article by Henan YuFeng Heavy Machinery finishing release, reproduced, please indicate the source!
