AMETEK Land: cleaner and more efficient glass furnaces

Improved glass quality and reduced energy consumption with Thermal Imaging from AMETEK Land

As the world moves towards new fuels and technology aimed at reducing emissions and carbon footprints, new approaches to furnace design, monitoring and measurements are needed to meet these targets.

Glass manufacturers face many challenges in their daily operations, including the need for accurate temperature measurements in a variety of locations within the glass melting furnace.

A portable infrared thermometer, such as AMETEK Land’s Cyclops C100 L pyrometer, provides accurate, calibrated and traceable temperature readings of molten glass from different positions around the melt tank.

This can be supplemented by AMETEK Land’s NIR-B-2K-Glass imaging camera, available for fixed installation or as a transportable version, which adds significant advantages compared with visual imaging and point-temperature measurements.

The NIR-B-2K-Glass imaging camera produces high-definition thermal images with three million pixels; it can also take measurements between 600 and 1800 degrees Celsius (1112 to 3272 degrees Fahrenheit) from any point in the image. In addition, a permanently installed thermal imager actively records all necessary and useful data, allowing the video to be stopped at any frame. This means measurements can be taken of all ports at exactly the same point in the process, allowing reversals to be tuned more accurately.

Structural damage caused by high temperatures can also rapidly be detected before it turns into a major problem. If a crack is developing in the refractory, it can show up as a cold area where the air is being pulled in. The NIR-B-2K-Glass imaging camera accurately profiles the temperature of the entire furnace through a small opening in the furnace wall.

Benefits include providing access to data that previously would have been either time consuming or impossible to collect. In addition, the operator is free to focus on specific areas of interest, measure live data points and store the data for future analysis.

Increased melt tank efficiency, improved product quality and reduced process costs are achieved through monitoring the live thermal video inside the melt tank, reinforcing the key measurements provided by the Cyclops C100L.

Philippe Kerbois, Global Industry Manager – Glass, said, “Using thermal imaging in glass operations results in many measurable benefits. Operators can— in a safe, timely way — collect valuable data that they can utilise and store while ensuring the quality of the glass and extending the life of the furnace. This all leads to reduced costs and an improved process, as well as working towards reduced emissions and carbon footprints.”
