摘要： Glasses are provided that are highly transparent and have very good resistance to solarisation. The resistance to solarisation is favoured to a special extent by the production method. The concentrations of reduced polyvalent ion species are reduced by targeted use of bubbling with an oxidising gas. Methods for producing glasses and to the uses thereof, particularly as core glasses in optical waveguides, are also provided.

摘要： An apparatus for manufacturing glass includes a furnace. A doghouse of the furnace receives and melts solid-glass forming material using one or more submerged combustion burners. An elongated tank positioned downstream of the doghouse includes a melting chamber, a refining chamber, and a thermal conditioning. The melting chamber has in inlet through which molten glass is received from the doghouse. The refining chamber is positioned downstream of the melting chamber and receives molten glass from the melting chamber. The thermal conditioning chamber is positioned downstream of the refining chamber and receives molten glass from the refining chamber. Additionally, the thermal conditioning chamber delivers molten glass to a glass forming machine.

摘要： Submerged combustion glass manufacturing systems include a melter having a floor, a roof, a wall structure connecting the floor and roof, and an exhaust passage through the roof. One or more submerged combustion burners are mounted in the floor and/or wall structure discharging combustion products under a level of material being melted in the melter and create turbulent conditions in the material. The melter exhausts through an exhaust structure connecting the exhaust passage with an exhaust stack. The exhaust structure includes a barrier defining an exhaust chamber having an interior surface, the exhaust chamber having a cross-sectional area greater than that of the exhaust stack but less than the melter. The barrier maintains temperature and pressure in the exhaust structure at values sufficient to substantially prevent condensation of exhaust material on the interior surface.

摘要： There is provided a process for producing molten glass, which is capable of easily increasing the H2O content in glass melt with excessive generation of convention of the glass melt being reduced.One mode of the process for producing molten glass according to the present invention is characterized to include a material melting step for melting a raw glass material in a melting furnace to prepare glass melt; a water-molecules supply step for supplying a water-molecules supply gas into the glass melt flowing from an upstream end of the melting furnace toward a downstream end of the melting furnace; and a refining step for degassing, under a reduced pressure atmosphere, the glass melt flowing out of the downstream end; wherein a position where the water-molecules supply gas is supplied in the water-molecules supply step includes a first position and a second position from downstream to upstream in a flowing direction of the glass melt in this order; the first position is a position away from both of the upstream end and the downstream end; and the second position is a position closer to the upstream end than a center of a distance between the upstream end and the first position in the flowing direction of the glass melt.

摘要： Processes and systems for producing glass fibers having regions devoid of glass using submerged combustion melters, including feeding a vitrifiable feed material into a feed inlet of a melting zone of a melter vessel, and heating the vitrifiable material with at least one burner directing combustion products of an oxidant and a first fuel into the melting zone under a level of the molten material in the zone. One or more of the burners is configured to impart heat and turbulence to the molten material, producing a turbulent molten material comprising a plurality of bubbles suspended in the molten material, the bubbles comprising at least some of the combustion products, and optionally other gas species introduced by the burners. The molten material and bubbles are drawn through a bushing fluidly connected to a forehearth to produce a glass fiber comprising a plurality of interior regions substantially devoid of glass.

摘要： Methods and systems produce a molten mass of foamed glass in a submerged combustion melter (SCM). Routing foamed glass to a fining chamber defined by a flow channel fluidly connected to and downstream of the SCM. The flow channel floor and sidewalls have sufficient glass-contact refractory to accommodate expansion of the foamed glass as fining occurs during transit through the fining chamber. The foamed glass is separated into an upper glass foam phase and a lower molten glass phase as the foamed glass flows toward an end of the flow channel distal from the SCM. The molten glass is then routed through a transition section fluidly connected to the distal end of the flow channel. The transition section inlet end construction has at least one molten glass inlet aperture, such that the inlet aperture(s) are positioned lower than the phase boundary between the upper and lower phases.
