Produced by HGH, a pioneer company in the field of thermography equipment for heavy industry, KILNSCAN scanner offers the best resolution, flexibility and accuracy, enabling to detect even the smallest brick damage in all rotary kilns, regardless of its configuration.
Scanners are tools that have long been known by rotary kiln operators. The use of scanners has become the standard in many industries, as they provide many important information such as tracking shell temperature, providing real-time alerts of extreme hot spots, and the condition of the incision inside the kiln.
Why is excessive thermal warp a problem for rotary kilns?
Thermal warp is the tendency of deformity caused by thermal differences that may occur along the surface of the kiln shell. Coupled with the rotation and load of the kiln, this trend causes periodic flexions and efforts along the kiln. This situation decreases the long-term reliability of the unit, load fluctuations on the relays and rings, warps in the rings, reduction of the refractory life due to overloading of the refractories in that region as a result of local ovalization, overloading of the drive group due to the periodic changing stresses and permanent damage and deformities on the shell in the long term.
How does KILNSCAN produce solutions?
KILNSCAN scanners collect information by making very precise measurements, making it possible to know exactly the temperature and therefore thermal differences at every point of the shell.
This allows the HGH-specific “THERMAL SHOCK MONITORING” algorithm to provide real-time information about the bending tendency of the shell axis; A moving view of the kiln axis is presented to the operator with a graph showing the potential magnitude of the lateral movement of the shell.
The benefits of this feature go beyond refractory and process monitoring, enabling short-term actions to prevent long-term damage to mantle and related infrastructures.
