Glass melting is still highly-energy consuming which bothers many technologists dealing with the issue of how to competewith other materials. Glass melting is a complex process consisting of several sub-processes which are ordered in a seriesor in parallel with their kinetics and ordering determine the effectiveness of the entire melting process. The most importantsub-processes during production are sand dissolving and bubble removing (fining), both being performed mostly successivelyin a commercial melting space and consuming a lot of energy. In the continuous melting process, the route of the melt flowthrough the melting space is another factor determining the melting efficiency. The new quantity, utilization of the meltingspace has been introduced recently which quantitatively evaluates the character of the melt flow with respect to both subprocesses.Using space utilization, a simple rectangular melting space with a controlled melt flow was examined whichperforms both homogenization processes in parallel, substantially increasing the melting performance and reducing theenergy consumption. As a theoretical tool, the commercial mathematical model has been applied (Glass Model) whichcalculates using the experimental data of both processes. The derivation of utilization and some summarizing results arepresented in this article. The further current aim resulting from the results in this part will be to deliver an overview of themelting techniques and subsequently discuss possibilities for both implementing the module in real technology and improvingthe melt flow in the contemporary commercial melting furnace.
