87th Glass Problems Conference (GPC)
The 87th Glass Problems Conference returns to Toledo, USA, from 14th till 17th September 2026, bringing together hundreds of glass industry professionals for education tracks, exhibitor networking, and short courses.
Abstract 1 : Supporting the Evolution of Glass Furnaces Through Advanced thermo-mechanical Simulation of Electrofused Crowns
The evolution of glass melting technologies, such as oxy-combustion and hybrid glass furnace, aimed at improving the energy consumption of furnaces and reducing greenhouse gas emissions, also involves changes of refractory materials lining. We can observe a broader use of electrofused AZS or high alumina for these new generation glass furnaces crown.
The finite element FEM numerical simulation tools we have developed at SEFPRO, along with our deep knowledge of the high temperature physical and mechanical properties of fused cast refractories, can provide valuable insights regarding the behavior of electrofused crowns. They allow us to anticipate the effects of temperature changes, thermal cycling, heating up on the crown ring deformation and additionally, for large-span crown, their long-term deformation capacity (creep) can be evaluated
The influence of design parameters (thickness, insulation, geometry) can also be studied for crown behavior understanding. During the presentation, we will discuss through generic cases regarding container and flat glass furnace showcasing the new possibilities offered to help glass manufacturers effectively manage the use of electrocuted crown.
Abstract 2 : Tapping into LCA Insights for Cost Saving and GHG Reduction in Glass Industry
Life Cycle Assessment (LCA) is a robust methodology used to quantify environmental impacts, such as greenhouse gas (GHG) emissions, across all stages of a product’s life cycle, from raw material extraction to endoflife. Beyond calculating total emissions, LCA enables identification of the specific processes or life cycle stages that contribute the most to overall impacts, commonly referred to as “hotspots.” These hotspots offer strategic opportunities for not only targeted decarbonization but also for cost saving.
Glass Service Group has developed a portfolio of technologies and services designed specifically to increase process efficiency resulting in both energy saving and GHG reduction for glass industry. Solutions such as ES III+, the Glass Furnace Model (GFM), high-efficiency FlammaTec burners, and FIC advanced electric boosting system provide pathways to improved energy efficiency, optimized furnace operation, and therefore reduced cost besides lowering combustion and processrelated GHG emissions.
This paper provides an overview of the LCA methodology as applied to glass manufacturing and demonstrates how hotspot analysis can support operational, investment, and decarbonization decisionmaking. We also illustrate how GS Group technologies can be applied to ensure cost reduction beside decarbonization for glass manufacturing.
