A new system for kiln shell temperature monitoring is now available. It is suited to monitoring, control, and analysis of rotating kilns primarily used in cement and lime production, as well as on rotating kilns processing a wide variety of materials in primary minerals processing
Raytek now has available its CS200 process imaging system. The combination of infrared sensor technology and a powerful, industrial software program allows accurate detection and monitoring of refractory hot spots to prevent costly kiln damage and extend production runs between refractory replacement.
The CS200 expands on the hugely successful CS100 kiln shell-monitoring product, which has seen over 170 installations worldwide.
Existing CS100 system features include full-color thermograms of the kiln surface, user-defined alarms, automatic fan control and extensive historical data analysis capability. The new CS200 systems builds on this base and increases the number of lines scanned per revolution to 200, adds OPC server functionality, more powerful database applications, and full integration of options that were stand-alone accessories in the older system.
Most notably, multiple point sensors can be installed and configured to monitor portions of the kiln ‘shadowed’ from the main sensor by physical obstructions and the results displayed as one homogenous thermogram. Similarly, a separate sensor is available to monitor the burning zone of the kiln with the data will seamlessly incorporated into one common display.
Options previously available, such as the Live Ring Migration software to monitor tire slip, are still supported by the new product but now the results are fully integrated into one display allowing the operator to monitor the complete kiln without switching back and forth between different applications. The integration does not stop at the display; all error reports and alarm reports are now fully integrated, as is the OPC interface with other applications.
The hardware has also been significantly enhanced with ease of installation and use in mind and as much as is feasible, connection boxes are pre-wired at the factory.
