The operating principle of the IS3 Scanner system is based on infrared temperature measurement technology applied to rotary kilns used in the lead recycling and processing industry.
The sensor detects infrared radiation signals, from which the surface temperatures of the kiln are calculated. These temperature readings are digitally collected by the central processing unit, processed, and displayed as either a temperature profile along the kiln or a complete thermographic image of the kiln surface on the PC monitor.
By using the shell temperature readings, the thermal conductivity characteristics of the refractory lining, and calculating heat losses due to radiation and convection, the system estimates the refractory thickness and displays this data in the form of a thickness distribution histogram. With this information, operations personnel can estimate the remaining service life, thereby optimizing kiln operation.
The system allows configuration of up to 4 alarm zones, which can be defined at any point along the kiln. These zones trigger a digital output signal when the temperature exceeds a predefined threshold, instructing the process controller to either raise an alarm or execute a predetermined control action.
Key Features:
- Online monitoring of rotary kiln shell temperature
- Prevent mechanical damage risks due to the formation of hot spots on the shell
- Early detection of refractory brick failure
- Estimation of refractory lining thickness
- Evaluation of temperature distribution and thermal profile within the kiln
