Scientific and Technological Conference
The Scientific and Technological Conference is a professional event taking place from 18–20 May 2026 in Ustron, Poland. It brings together experts from industry, research, and technology sectors to explore how the glass industry is evolving in response to environmental and economic pressures.
Meet Glass Service at the Conference
Abstract: GFM – enhancing the software to maximize the value for customers
The Glass Furnace Model (GFM) is an internally developed software in Glass Service, a.s. (GS) for understanding the processes in glass melting furnaces. It uses the CFD mathematical modelling approach and is perfect for evaluation and visualization of the most important parameters within the furnace (e.g. glass and combustible flows and temperatures, etc.).
As the sustainability is of a huge importance nowadays, the optimization processes in glass melting are crucial. However, to get insight into the furnace during the operation is very complicated or even impossible. This is exactly the right time for using mathematical modelling. The whole glass furnace could be simulated and any particular region of it can be examined in the model. What it basically means is that the model can predict influence of changes in furnace geometry, operational parameters, fuel used and much more without any risk of lowering the real production or even damaging the equipment.
Another way to have more sustainable production is to “go hybrid or electric” (using higher ratios of electric power instead of fossil). This again can be well simulated using GFM and an example will be discussed.
All the above mentioned targets mean a shift from “standard” furnaces (the geometry design, operational parameters, etc.) towards a new solutions. It is therefore very important also to update the modeling software so that the new solutions can be simulated. The GS development team works hard on this, tightly cooperating with the customers.
