Modular Melting: Part 1: Industrial glassmelting process analysis
article
The difference between the minimum residence time versus average residence time, the high amount of energy absorption in the initial stages of melting were investigated. The total required, minimum residence time for glassmelting processes is the summation of the necessary minium times for batch melting, sand grain dissolution, fining, refining and final homogenization. During the dissolution of a sand grain, a SiO2-rich boundary layer is formed in the melt surrounding the grain, which lowers the basicity of the melt in that layer. Substantial energy savings and process improvements can be realized by actual modularization of commercial glassmelting processes.
