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.
Refiner for refining glass in thin film form in which glass flows by gravity and/or centrifugal force, comprising at least one device capable of being rotated in order to carry out centrifugal refining, the device having internal walls substantially defining the shape of a vertical hollow cylinder at least in the central part of the device, inside which cylinder there are vertical partition(s), wherein the top of the partition(s) constrain molten glass flowing out between the internal walls and the partition(s).
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 device having internal walls substantially defining the shape of a vertical hollow cylinder at least in the central part of the device, inside which cylinder there is at least one partition in the form of a cylindrical zone, wherein the top of the partition(s) constrain molten glass flowing out between the internal walls and the partition(s), and a metal plate adapted to stop the molten glass to be refined from dropping, the plate forming with the top of the partition(s) a glass-collecting basket, adapted so that glass tends to rise and then pass over the partition(s) before subsequently flowing out in the form of a thin film.
