    摘要： Glass melting process, comprising: the introduction of a vitrifiable solid charge (11) into a furnace (1), the heating and the melting of the charge (11) in the furnace (1), so as to obtain molten glass (17), the discharge of the molten glass (17) from the furnace (1) and the discharge of a CO 2 -containing gaseous effluent (20) from the furnace (1), the charge (11) comprising at least one carbonate undergoing a dissociation reaction and releasing gaseous CO 2 (18) when the charge (11) is heated and melted, the gaseous effluent (20) discharged from the furnace (1) being used to produce, by carbonation with the CO 2 present in the gaseous effluent (20), at least one additive (33) in the form of an alkali metal or alkaline earth metal carbonate, at least a part of which is incorporated in the charge (11) which is introduced into the furnace (1), the heat for heating the charge (11) in stage b. being provided by:
    • by electric heating,
    • by combustion of a non-carbon-based fuel (12) with an oxidant (13), optionally in combination with electric heating, or
    • both by combustion of a non-carbon-based fuel (12) with an oxidant (13) and by combustion of a carbon-based fuel with an oxidant, optionally in combination with electric heating.

    摘要： Systems and methods for controlling the flow of vitrified material. In at least some embodiments, a vitrified material control system comprises a melt chamber (8) configured to contain a molten material (27) during operation of the control system; a siphon valve (11) configured to facilitate a flow of the molten material from the melt chamber; and a vacuum-generation system (26, 15, 16) configured to controllably deliver a vacuum to the molten material in the melt chamber and to thereby regulate a flow of the molten material from the melt chamber. In other embodiments, methods of controlling a flow of molten vitrified material from a heating device are disclosed. The methods may include, for example, applying a vacuum to the molten material to control a dwell time of the molten material in a vessel of the heating device and regulating the vacuum based on a measured temperature of the molten material.
