Improperly designed and/or operated furnaces and front-end delivery systems can cause a number of problems to the forming operations, ranging from poor quality with defects to shortened furnace life. CFD has become an increasingly important tool for glass manufacturers to guide and optimise such system designs and operations. The current work is part of an effort to leverage CFD resources in the decision making processes in engineering, operations and businesses. The furnace modelling was performed using the recently implemented bach melting model jointly developed by Owens Corning and Fluent Inc., which feature three-dimensional simulation of an entire glass furnace including combustion, bubbling and electrical boosting. The thermal coupling procedure between the combustion space, batch and the melting take is discussed. The modelling results are presented.
