Estimating the term…
The subject of the invention is a process for melting and refining vitrifiable materials, such that all or part of the thermal energy necessary for melting the said vitrifiable materials is supplied by the combustion of fossil fuel(s) with at least one oxidizer gas, the said fuel(s)/gas or the gaseous products resulting from the combustion being injected below the level of the mass of vitrifiable materials (7). The refining of the vitrifiable materials after melting takes place at least partly in the form of a “thin layer”. The invention also relates to the device for implementing the process and to its applications.
1-37. (canceled)
Refiner for refining glass in thin film form, comprising at least one device capable of being rotated in order to carry out centrifugal refining, the internal walls of the device substantially defining the shape of a vertical hollow cylinder at least in its central part, inside which cylinder there are partitions over at least part of its height so as to constrain molten glass from flowing out between the internal walls and the partitions.
