KILNCOOLER HOTSPOT

Exploring Traditional Approaches
 
As the use of secondary fuels continues to rise, characterized by their relative heterogeneity, fluctuations in the combustion process become more pronounced. Consequently, this places greater stress on the refractory lining and the kiln shell, potentially leading to the formation of hot spots. To mitigate this challenge, large cooling fans, which circulate ambient air, have become commonplace.
 
 
However, employing aircooling via fans comes with notable drawbacks:
 
**Due to the low heat transfer/coefficient capacity of air, a substantial throughput is required.
**High consumption of electrical energy is inevitable.
**Cooling cannot be precisely targeted to address specific hot spots along the circumference of the kiln shell.
**The operation of fans results in significant noise emissions.
