“…Pre-heating removes some water, CO 2 and remaining organic compounds in the batch resulting in lowering the required the batch-to-melt energy. However, loose glass batch itself has problems with dusting and segregation [1,2]. Dusting results in loss of raw materials and segregation causes loss of homogeneity.…”

In the conventional soda-lime glass production, loose raw materials are normally mixed into a glass batch for melting. Dusting and segregation of the loose glass batch are always occurred during the melting process inside the glass furnace. Also, the loose glass batch has low thermal conductivity which limits the glass melting ability and pulling rate of the glass furnace. Granulation and preheating of glass raw materials have been proposed to solve the problems. In this study, the granulated soda-lime glass batch (SiO2 50% Na2CO3 22.5% CaCO3 12% NaAlSi3O8 9.5% BaCO3 2.5% ZnO 1.75% Sb2O3 1% and K2CO3 0.75% by weight) was prepared to study the melting ability in an electric furnace. The granulated batch was also preheated at 500-600°C before melting. The preheating temperature was matched to the temperature of flue gas at the bottom of the stack in the glass furnace. The purpose behind this was aiming to recover the waste heat from the furnace. The experiment exhibited the increased melting ability for the granulated-preheated glass batch

“…In such common method of making glass, it always presents dusting and segregation problems because of the different densities and particle sizes of the components of the batch [1,2]. Thus, the traditional melting of glass is an inefficient process because loose glass batch has low thermal conductivity which limits the melting rate of glass and pulling rate of the furnace [3,4].…”

The physico-chemical processes and individual factors affecting the uniformity of the mix both when the mix components are being mixed in a mixer in a sectional line and when the mix is transported and loaded into a glass-making furnace are analyzed. The effect of moistening on mix quality in obtaining glass mix and transporting and loading the mix into the furnace by means of mix loaders is determined. The temperature factors ensuring that the mix temperature when the mix is loaded into the furnace is no lower than 35 -40°C are determined. The degree to which mix is removed with respect to both quantity and individual components on the loading hopper and regenerators along the glass-making furnace is determined. The direction for further research on optimizing the mix preparation process in order to increase the operational efficiency of a glass-making furnace is proposed on the basis of the results obtained in the present work.
