摘要

Temperature measurement at critical locations in the production process is essential for efficient control and optimization of glass manufacture and processing. An innovative thermal imaging solution for glass furnace applications using a Near Infrared Borescope provides a true-temperature radiometric image, so live temperature values can be obtained from >324,000 pixels and provides continuous coverage 24/7. The solution allows long term data trending for fuel optimization plus enables thermal optical profiles to be measured continuously and specifically during furnace reversal. Example case study shows how a leading container glass manufacturer has used this infrared temperature measurement solution to highlight issues within a glass melt tank, enable them to make necessary repairs and then optimize firing to achieve new record pull rates on an asset nearing the end of its campaign. Alarms and temperature isotherms also provide the manufacturer with long-term asset protection against over-heating and condensation zones. On the firing side, clear correlations have been identified between apparent flame temperatures and corresponding NOx, allowing these findings to be used potentially as part of emission and de-NOx reduction programmes.
