Operating glass melting plant, comprises providing flow-influencing element in a portion, coating flow-influencing element with metal sheet made of iridium or high iridium-containing material, and providing control device

Operating a glass melting plant (1) comprising a portion having a melting region (2) for melting a liquid glass melt (8), a refining zone (3) for refining the molten glass and/or a conditioning section (4) for conditioning the glass melt, comprises: providing at least one flow-influencing element, preferably an overflow wall in the portion to influence a flow profile of the glass melt; coating the flow-influencing element with a metal sheet made of iridium or high iridium-containing material; and providing a control device for controlling the glass melting plant. Operating a glass melting plant (1) comprising a portion having a melting region (2) for melting a liquid glass melt (8), a refining zone (3) for refining the molten glass and/or a conditioning section (4) for conditioning the glass melt, comprises: providing at least one flow-influencing element, preferably an overflow wall in the portion to influence a flow profile of the glass melt, where the portion is associated with the heating devices; coating the flow-influencing element with a metal sheet made of iridium or high iridium-containing material; and providing a control device for controlling the glass melting plant, where the control device is designed such that the temperature of the portion is increased in a first heating step to a critical temperature in the absence of a glass batch insert or glass melt, in which oxidation of the metal sheet is performed, the temperature of the portion is increased in a subsequent second heating step continuously to an operating temperature in the absence of the glass batch insert or glass melt, and the portion is filled with the glass melt in the third step, and a glass flow is formed, which is used for coating the flow-influencing element. An independent claim is also included for a glass melting plant, comprising the portion having melting region for melting liquid glass melt, refining zone for refining the molten glass and/or conditioning section for conditioning the glass melt. Die Erfindung betrifft eine Glasschmelzanlage sowie ein Verfahren zum Betreiben einer Glasschmelzanlage. Die Glasschmelzanlage weist einen Abschnitt mit zumindest einem strömungsbeeinflussenden Element, insbesondere in Form eines Überströmwalles auf, wobei das strömungsbeeinflussende Element mit einem Metallblech aus Iridium oder einem hoch-iridiumhaltigen Material überzogen ist. Statt aufwändiger Oxidationschutzmaßnahmen wird die Glasschmelzanlage erfindungsgemäß trocken hochge
