KilnCooler Hot Spot
Water based kiln cooling
Control your kiln shell temperature.
Reliable and effective cooler for kiln shell.
Due to the increasing usage of secondary fuels, which are relatively inhomogeneous, there are more fluctuations in the burning process. This leads to increased burden for the refractory and the kiln shell—hot spots may occur. In order to reduce this burden, large cooling fans, which are blowing ambient air, are widely used.
Unfortunately this type of cooling shows some disadvantages:
Efficiency by water cooling
To overcome these disadvantages KIMA‘s KilnCooler uses waterspray nozzles and precise dosing valves, which are controlled by an infrared temperature sensor. The waterspray of an individual nozzle is switched on only, while its infrared sensor detects a hot spot.
The waterspray cooling is efficient and “on the spot”.
The waterspray is controlled by a FUZZY-controller which uses infrared sensors to precisely locate hot spots on a
Cooling down a hot spot
By application of KilnCooler, a hot spot can be cooled down rapidly but careful, avoiding any shrinkage of the kiln
shell—cooling rate is up to 2 Kelvin per minute.
