ELECTRIC MELTING OF GLASS (INTRODUCTORY TRAINING)

15 - 18 September 2025
14:00 - 17:30 CET
EINDHOVEN (NL) AND/OR ONLINE

In the continuous energy transition to lower CO2 emissions, electricity will be a crucial asset.  Electric melting is a well-established technology for smaller-scale specialty glass production. As the technology begins to be adopted for commodity glass production, numerous factors must be carefully considered, from effective systems inside and outside the furnace to operating the furnace in the most efficient way. The goal of the course is that you leave with a practical understanding of the entire melting system.

Contents

• Electric melting, heat transfer, and energy
• Purpose of electrical boosting, from sustainability to flexibility
• Melting zone, barrier, throat, and feeder boosting
• Electrode material, types, holder, and cooling systems
• Positioning of electrodes (in and outside the furnace)

After the training you will
• Be able to follow all the electrons from the power plant through multiple transformers into your glass melter. (… and even correct the ones that go the wrong way)
• Understand the many advantages of electrical boosting
• Have a clear overview of what needs to be considered to increase the electric share in your energy mix
• Know how to choose the proper electrical system for your specific production, from the choice of the right transformer to the choice of the electrode density and control system
• Be able to calculate relevant glass properties like resistivity and resistance
• Know what to focus on when operating your system

Training methods
We offer a blended learning approach by mixing e-learning, lectures, open discussions, exercises, and case studies in teams or individually. The number of participants per course is between 8 and 20 to maximize your learning experience. Participants always receive the presentations and a training certificate.

Level of seniority
This training is meant for junior professionals to skilled professionals seeking to deepen their knowledge.

Trainers
Sjoerd Stelwagen
Sjoerd Stelwagen studied Chemical Engineering at Eindhoven University of Technology. Directly after his study he started as a Technical Specialist at the Furnace department of Ardagh Glass in Dongen, The Netherlands, where he later became Batch and Furnace Manager. He then evolved as EHS manager for the Benelux plants. With more than 16 years of practical glass making experience, he joined Celsian in 2021 to work as a project manager and trainer.
Christian Räbiger
Christian Räbiger studied process engineering at the Technical University of Freiberg, specializing in glass, ceramics, and building materials. He joined the technology department of Sorg for 8 years where he designed, modeled, and optimized multiple glass furnaces to improve the energy demand and production quality. He also offered troubleshooting and technical support. He then moved to Swarco for 4 years. His activities included planning furnace reconstructions and new furnaces, R&D, and project work. In 2023, he joined CelSian as technical director for the EU area.
Price Training costs € 2.300,- per participant.
