Temperature monitoring is possible whatever your kiln configuration, thanks to the KILNSCAN scanner! Thermography imaging systems are more and more used to monitor the temperature of critical areas in your industrial manufacturing process. As one of the pioneers in thermography imaging systems, HGH offers efficient support to the plant operators through the KILNSCAN scanner, monitoring the kiln shell temperature.

Rotary Kiln Shell Temperature Monitoring with KILNSCAN:

KILNSCAN is a benchmark thermal scanner, with the highest resolution and sensitivity, displaying the full temperature map of the kiln, with a high frame rate.

Thanks to KILNSCAN, the maintenance of your rotary kiln is easier; as it detects hot spots in real-time and measures brick and coating thicknesses.

Complex configurations and imaging challenges:

1. Long kilns:

  • Large field-of-view scanners:

For long kilns, the high optical resolution of the scanner allows to install it far enough from the shell to capture its whole length, while seeing small details and detecting hot spots corresponding to the failure of a single brick anywhere along the kiln. If, due to constraints in relation with the boundaries of the plant itself, it is not possible to install the scanner head so far away from the kiln, our exclusive 140° large field of view will allow to see it fully from a reduced distance using a single sensor head. 

  • Two-scanner configuration: ​​​​​​

In the case of a very long kiln with a limited free distance, two scanners can be installed side by side, at a distance of one fourth of the length of the kiln, both scanners aiming at a different portion of the kiln. The full kiln thermal image is obtained by the seamless combination of the scanners’ images. See below:

2. Kiln inside a building, and very limited free distance:

With a 140° extended scan angle, the full shell is covered even in a building with a limited free space!

3. Beams and pillars masking the shell: 

Depending on the configuration, pillars may be obstructing the field of view and generating shadows. Our solution:

  • Image fusion for complex shadows elimination: In complex environments where obstacles prevent from seeing the whole kiln, the thermal profile is obtained by the combination of the data of two scanners, both aiming at the kiln but from a different viewpointData are concatenated to keep the best of each scanner, thus providing the operator a full and seamless thermal image of the kiln.
  • Complementary shadow pyrometers: When small obstacles such as poles or beams hide a few short portions of the kiln, or to monitor small areas hidden behind tyres, shadow pyrometers can be installed locally and their data again integrated seamlessly into the image of the scanner to reconstruct an unobstructed view of the whole shell.
