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).
