Validation of a mathematical glass tank model

Abstract

In the past mathematical modelling of glass furnaces concentrated on the redesign and optimization of such aggregates. For the future, it is conceivable that such models will also be used for the control of glass furnaces. The present study showed that an increased occurrence of bubbles due to increased glass pull can be found in the results of the model, while a corresponding link between model and practice could not be found for solid inclusions. As a main cause for the limited correspondence between modelling and practice the dominating influence of recycled cullet and the frequent changes of the glass pull could be identified.
