MODELLING OF GLASS REFINING KINETICS PART 1. SINGLE BUBBLES

L. Němec, J. Kloužek

The modelling of glass refining kinetics plays the most important role for the industrial melting efficiency and glass quality control. Among different mathematical models of the process, the simplified descriptions of bubble behaviour, based on experimental measurements, may be most acceptable for mentioned applications. This work presents two models of single bubbles in glass melts: the steady state complete model and the simplified model utilizing the experimental data as are bubble growth rates and bubble stationary compositions. The verification of the simplified model is mentioned. The results of chemical and combined refining are presented, based on experimental data for the simplified model.
