Glass Service (GS) held a successful 15th International Seminar on Furnace Design – Operation and Process Simulation.

The event was attended by approximately 150 glass experts from 25 countries including USA, Mexico, Japan, India, Saudi Arabia, Russia, New Zealand and several European nations including UK. Feedback from participants was positive.

In conjunction with the Seminar, the ICG's Technical Committees 15 and 21 held their meetings, while a User Meeting of the GS Glass Furnace Model (GFM) also took place, attended by 40 glass specialists.

The Seminar highlighted the latest developments in furnace optimisation and CO2 reduction with support from simulations and advanced control.

There were contributions from: Johns Manville, Owens Corning, AGC, SEFPRO and FIC UK among others.

It continued on new developments around Industry 4.0 - what it will bring to further automatise and optimise the glass melting process, such as automatic batch monitoring integration.

The 7th GS Modeling Award was given to Bruno Purnode from Owens Corning. Bruno has made a significant contribution to the use of simulation tools within his company and at conferences globally.

The seminar took place at the Hotel Horal mountain resort in Velke Karlovice, Czech Republic on May 22 and 23.

The event takes place every two years and brings together glass experts from around the world to discuss the use of simulation and control tools, with the goal of optimising the glass melting and forming process. The next event will take place on June 16 and 17, 2021.
