A visible thermal imaging system provides high quality lime kiln process monitoring for pulp mills. Combining the camera temperature information with process controls can improve combustion optimization and reburned lime quality and reduce emissions. The system, manufactured by Valmet, also allows visual evaluation of flame shape, size and temperature profile. Reduced maintenance costs and greater visibility during start-up and full load conditions can also be achieved.

The system is an air-cooled, HD visible camera paired with a high resolution thermal sensor for real-time product temperature measurements. Designed for comprehensive observation and analysis of kiln environments, it provides high image quality from start-up to full load conditions.
