Bubbling presence in the furnace has proved its intensifying influence on a melting process, which was manifested by positive influencing of glass melt temperature (higher heating up ). The same positive influence of bubbling has been noticed also in case of a glass melt flow. Bubbling in the furnace has resulted in the increase of glass melt velocity and, consequently, in speeding up the reactions between non-homogeneities and the melt, as well as in quicker glass melt refining. A double-row arrangement of bubbling nozzles has appeared to be more advantageous, as it lead to the global heating up in the furnace increased by several tens degrees ( 3 0 - 6 0 ° C ) and to the increase of velocity by about 30%.enghttps://creativecommons.org/licenses/by/3.0/de/660ArticleKonferenzschrift
