While the end goal of decarbonisation may be known, it is key to establish the starting point of the journey in order to ensure that the correct path is taken to achieve a sustainable solution in the glass industry.

Recent container and float glass case studies illustrate how Near Infrared (NIR) In-furnace Thermal Imaging surveys can show the current position. The output provided is best interpreted as a CFD model which can validate a digital twin.

Typically, the initial process is to establish if the furnace thermal profile is optimised for the furnace design. Additionally, in parallel, any refractory hot/cold spots should be identified, and the top of the regenerators inspected.

By utilising the patented reflection method, it is possible to show that the ‘mirror’ is, in fact, a micro-layer of foam which is insulating the heat transfer to the glass. Suppressing this foam can create energy cost savings in the region of up to six figures. By sealing the holes and reducing the parasitic air, operators can save 3-5% reduction in energy, plus a corresponding reduction in CO2. By starting with the low-hanging fruit, validating models, and defining a path from a known starting point, furnace operators know where they are starting from, even if destinations may change.

In February 2020 Simpson C&E had to cancel a Training Course in Singapore due to Covid. A bespoke online training course for one of the companies who had planned to attend identified that they had a new furnace, but the energy was significantly above budget by several hundred thousand.

Due to COVID travel restrictions, engineers couldn’t travel to the location. However, the AMETEK Land NIR-Borescope-2K-Glass (NIR-B-2K-Glass) was sent to the location, and Global Field Service Engineer for Glass, Mark Briggs, provided online remote training to the site personnel on how to operate the equipment, while the customer engineering team made the physical measurements.
