The apparatus includes a connecting tube assembly having a conduit for conveying the molten glass, the conduit including at least two flanges and a sealing member disposed between the at least two flanges around an outer peripheral region of the flanges, thereby forming an enclosed volume between an outer wall of the conduit, the at least two flanges and the sealing member. An atmosphere within the volume may be controlled such that a predetermined partial pressure of hydrogen or a predetermined partial pressure of oxygen may be maintained within the volume. A current may be established between the at least two flanges to heat the conduit.

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： A precious metal structure which has an internal gas permeable membrane is described herein for a glass manufacturing vessel configured to have molten glass flow therein. The internal gas permeable membrane can be supplied with an atmosphere of gas (or gases) to control the flux of hydrogen into our out of the molten glass or otherwise improve the production of the molten glass. In this manner, the undesirable detrimental reactions that can occur at the interface of the molten glass and precious metal interface which can cause defects in the molten glass such as bubbles or solid inclusions can be stopped or at least substantially reduced.

摘要： The invention includes a method and an arrangement for influencing the flow of glass melts in a controlled way during the transfer from the melting furnace to a processing process. The simultaneous generation of electric and magnetic fields generates a force in the glass melt which boosts or inhibits the melt flow and acts substantially in the same direction as or in the opposite direction to the main direction of flow. It is in this way possible to control the melt flow without affecting the temperature of the melt. Consequently, the invention is suitable in particular for the accurately controllable feeding of a homogeneous glass melt to a glass production process.
