Over the last 25 years, CelSian has been developing a simulation software for glass furnaces. This simulation software, named GTM-X, is similar to the software used in weather forecasting and the automotive and aerospace industries. However, GTM-X is equipped with dedicated models that allow it to accurately describe the phenomena inside a glass furnace.

This presentation aims to showcase modelling as a necessary tool for furnace design and production as it allows us to extract the maximum out of our furnaces and set us up for the future.

The various possibilities by carrying out CFD simulations will be demonstrated. These include the ability to analyse critical flow patterns for product quality, gain an in-depth understanding of the melting behaviour with the use of different raw materials, accurately determining refractory contact temperatures and predicting refractory wear.
