Thermographic Inspection of Recuperative Furnace Arch at Mineral Wool Production
Method. The task was solved with the use of the thermographic system based on the scanning pyrometric transducers developed in the Omsk State Technical University. Transducers’ software transfers digital information from the transducers to the computer, visualizes and processes the colour image (thermogram) in real-time and provides its mathematical processing and storage. The thermographic system includes four transducers with rotating units, a control unit, a control computer and specialized software.
Results. The thermographic system has made it possible to visualize the real-time arch surface temperature field at the control computer screen as well as analyse and store the thermographic information. Thermographic information is also presented in tabular form on the screen together with the trends of maximal, minimal and average temperature for every arch zone.
Conclusion. The developed thermographic system for automated condition monitoring of recuperative furnace arch is used at OAO “AKSI” (Chelyabinsk). The system allows the personnel to prevent accidents and prolong interrepair time for the furnace.
