ANALYSIS OF ELEMENTARY PROCESS STEPS IN …
INTRODUCTIONR esidence time distributions, determined for batchand the glass, after batch fusion, in glass melting fur-naces show that the flow of material in the tank partlyfollows plug flow regime, but that also sections withstrong mixing and re-circulation flows exist. In the glassmelting tank, different zones should preferably corre-spond to different ELEMENTARY PROCESS STEPS . But, inmost industrial glass melting tank furnaces, these zonesare not physically separated from each other, and thedifferent processes in the tank may interfere. Thesebasic processes are: a). heating of batch up to "meltingor fusion" temperatures, b). fusion reactions to form asilicate melt and c). dissolution of sand grains in thisprimary silicate melt and final molten glass composi-tion, d).
