HEAT TRANSFER IN GLASS MELTING FURNACES (ADVANCED TRAINING)

27 - 28 September 2023
14:00 - 17:30
Eindhoven (NL) and/or Online

This training describes the fundamentals of heat transfer mechanisms in the combustion space, batch blanket and glass melt.

It focusses on radiative heat transfer in glass melts depending on the presence of the colouring ions and the redox state of the melt. The effects of new, emerging, sustainable furnace technologies, like hydrogen combustion and full electric melting on the heat transfer mechanisms are elucidated.

Contents:

  • Heat transfer in the combustion space

– Flame emissivity

– Effect of soot

– H2-rich flames

  • Heat penetration in batch

– In flame furnaces

– In electric cold-top furnaces

– Effect of cullet type and content

  • Heat transfer in glass melt

– Radiative heat transfer using a new model for predicting thermal radiation conductivity

– Convection in fuel-fired and electric cold top tanks

Trainers
Mathi Rongen
Mathi Rongen studied Applied Physics at Hogeschool Eindhoven. He started working at Philips Research Laboratories as research engineer and developed measurement set-ups for thermo-physical properties of silica glasses. In 1996 he joined Philips as development engineer responsible for improving the glass quality of TV and Lighting glass using CFD Glass Furnace Modeling. In 2006 he joined TNO Glass Group as R&D project manager. He is now senior consultant at CelSian, with a focus on executing melting trials and other customer projects in our laboratory.
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.
Oscar Verheijen
Oscar Verheijen obtained his PhD from Eindhoven Technical University before joining TNO as a R&D project manager and business development manager of sustainable technologies. He is now R&D and training team leader at CelSian, Board member of the GlassTrend, member of the steering committee of the Dutch Glass Industry (NCNG) and represents the NCNG at European level.
