Diagnosis and treatment of bubbles in glass production using a numerical Simulator

Abstract

A methodology to evaluate the bubble removing Performance of a tank furnace was proposed in previous papers. Since the operating data of the furnace being used for actual production can be udlized to examine the effectiveness of the above proposal, this paper deals with the verification issue when this methodology is applied to a real furnace. Additionally, various indirect indices, which have been advocated to evaluate the bubble removing Performance, are compared with the proposed direct Simulation. The results show that the phenomena experienced in the factory can be clearly explained and the direct Simulation has been proved to be very useful to diagnose and to treat bubbles during actual producdon.
