Monitoring the evolution of hot spots is the primary role of thermal scanning to detect any risk of permanent damage to rotary kilns. HGH provides leading-edge Kiln scanners, with the highest resolution and sensitivity. They can give early warnings of a single refractory brick fall.
For industries using rotary kilns in their manufacturing process, such as cement, lime, refractories, aluminium and iron ore production, detecting hot spots at an early stage is essential to preventing any interruption in production due to a fall of a refractory brick.
However, for clear and reliable kiln system evaluations, it is highly recommended to select a high performance instrument with enhanced spatial and thermal resolution (i.e. the spot size on a kiln must be small enough to detect the fall of a single brick and the infrared detector’s signal noise must be as low as possible to monitor positively small changes in temperature).
HGH’s Infrared scanners have the highest spatial resolution and thermal sensitivity on the market. They can detect hot spots at an early stage, evaluate in real time brick lining wear, coating thickness and even kiln axis warp.
Kilnscan provides :
Each individual refractory is under 24/7 vigilance. With a resolution inferior to a single brick, Kilnscan will warn, as early as possible, of any hot spot formation.
