Abstract:

The experimental and theoretical knowledge of industrial glass melting processes, acquired during the two last decades, opens a way to new melting concepts, characterised by high quality glass production from smaller, highly performing, flexible furnaces that have low energy consumption. Such concepts offer the potential for the production of new, high quality advanced glassy materials produced in small scale melting facilities. The key to successful developments lies in melting process analysis, partially free from industrial experience. This work presents a method for evaluating the effects of temperature, process time, flow conditions and insulation in a model melting space (simulating a melting tank) on energy consumption, melting performance and flexibility of the process to convert rapidly from one glass type to another type of glass, in terms of dissolution and bubble removal (fining). The requirement for completion of both homogenisation processes just prior to the glass leaving the melting space was maintained in all calculations. The calculations utilised laboratory sand dissolution times and fining times with the aim of finding theoretical optimum conditions for dissolution and bubble fining processes during glass melting. The results obtained under isothermal conditions provide a way to fundamentally improve both processes; particularly by process separation, application of controlled glass melt flows and special conditions for bubble removal.
