Influence of furnace design and operation parameters on the residence time distribution of glass tanks, predicted by 3-D computer simulation
article
A three dimensional, transient computer model is employed to calculate the flow patterns of molten glass in glass tanks. The model is based on a finite difference technique, using an implicit method to solve the coupled momentum- and energy equations. In order to assess alternatives for furnace design and operation parameters, the residence time distribution can be calculated. The residence time distribution is obtained by solving the transient concentration equation for stationary flow conditions, simulating tracer-experiments. This technique gives information about the macro-mixing in glass tanks, the location of 'dead-water' zones and possible short currents. For a fictive glass tank, some examples of how furnace design and operation parameters affect the residence time distribution are given. The examples that are chosen consider the influence of glass-pull, bubbling, flow-barrier and boosting.
