Fixed Furnace Thermal Imagers Ametek NIR-Borescope-2K-Glass

Descriptions

The NIR-Borescope-2K-Glass (NIR-B-2K-Glass) is a short-wavelength radiometric infrared borescope imaging camera, designed to produce high definition (1968 x 1476 pixels) thermal images, along with providing accurate temperature measurements from any of the three million temperature points in the image.

The camera measures temperatures in the range 1000 to 1800 °C (1832 to 3272 °F) and is suitable for float glass, container glass, borosilicate glass, and fibre glass melt furnaces.

ACCURATE TEMPERATURE PROFILING

With the NIR-Borescope-2K-Glass, it is possible to accurately and continuously profile the temperature of the entire furnace, including glass, refractory walls and port arches, and the crown/roof, with only a small opening in the wall. Thermal imaging inside refractory-lined furnaces, boilers and glass melt tanks normally requires the plant operator to cut large openings in the refractory to enable viewing of the critical area. This can cause significant wasted energy from heat loss and can be difficult to keep the opening free from debris. The NIR-B-2K-Glass only requires a small diameter hole through the furnace casing and refractory to accommodate the wide-angle lens tip. 

CONTINUOUS FURNACE MONITORING

The NIR-Borescope-2K-Glass offers significant advantages over the traditional methods of furnace monitoring. With the NIR-B-2K-Glass, it is possible to accurately and continuously profile the temperature of the entire furnace, including glass, refractory walls and port arches, and the crown/roof, with only a small opening in the wall. Thermal imaging inside refractory-lined furnaces, boilers and glass melt tanks normally requires the plant operator to cut large openings in the refractory to enable viewing of the critical area. This can cause significant wasted energy from heat loss and can be difficult to keep the opening free from debris. The NIR-B-2K-Glass only requires a small diameter hole through the furnace casing and refractory to accommodate the wide-angle lens tip. 

POWERFUL THERMAL IMAGING SOFTWARE

With the new IMAGEPro software it’s region of interest (ROI) can be user-defined and trended, showing max, min, and average temperatures and by using the included Playback view you can replay events and stop at any frame to measure multiple temperatures at the same point in time, particularly useful if you are measuring port arch temperatures at the moment of reversal.

BATCH COVERAGE AND CROWN TEMPERATURE MONITORING

Variation in batch coverage has a direct impact on furnace temperatures. The temperature clearly drops when the batch moves to the front of the furnace, and within the IMAGEPro-Glass software, ROIs can be used to set alarms for the furnace DCS and facilitate better control of the batch coverage by adjusting the batch charging direction and length. By monitoring the batch coverage near the throat, this critical ROI can help avoid large amounts (below 15%) of batch entering this area even for large pull rates and prevent production of glass defects.
