The demand for improved quality products is continuously increasing, with restrictions on emissions and energy use as boundary conditions. These competing demands make it complicated and challenging to operate glass furnaces at the optimal settings (in view of glass quality and process performance) while safeguarding furnace lifetime and minimize process instabilities leading to increased reject.
Over years, CelSian’s computer models of furnaces and forehearth systems are used for process improvement projects and many new furnace builds and rebuilds. Our application of models is thoroughly validated by lab experiments and industrial measurements. CelSian is proud to offer these services in a unique combination between high level glass technology knowledge (practical and experimental) and computer modelling.
Now the computer models are used in the engineering phase of advanced model-based control systems lowering project costs, increasing the working range and accuracy of furnace control systems. This approach has proven it selves in industrial applications for the glass industry resulting in temperature stabilization, energy reduction and reject decrease.
Our proprietary models describe the most important aspects of a complete glass melting furnace ''
GTM-X is a Computational Fluid Dynamics (CFD) tool for detailed modelling of physical and chemical processes in complex shapes. Running on different platforms, this multi-physics model permits a wide variety of materials to be simulated and many different physical equations to be addressed, including turbulence and combustion processes and their influence on glass melts. CelSian’s highly valued support team assists our customers for addressing specific requirements.
Please watch the movie below to get an idea of the possibilities of GTM-X.
Many years of experience confirm the abilities of CelSian modeling expertise, where validation data is created for new and existing glass melting furnaces and project results can be presented in a variety of different ways. A large portfolio of simulations is maintained in the CelSian database, helping to validate the accuracy of the latest models created on behalf of customers.
Via regular communication with the customer and based on the modeling results generated, recommendations for helpful improvements can be provided. Project results can be provided in a variety of different ways, ranging from interactive presentations to the provision of software tools where customers can use the results themselves. At CelSian, modeling results are combined with expertise.
