Abstract
Um flüssige Metalle in einem meist zum Transport geeigneten Behälter warmzuhalten ist es bekannt, einen Brenner in einem nach oben offenen, unterseitig geschlossenen Tauchrohr aufzunehmen, dessen Heizenergie über die Wände des Tauchrohrs auf die Schmelze übertragen wird.In order to keep liquid metals warm in a container which is usually suitable for transport, it is known to receive a burner in an upwardly open, underside-sealed immersion tube whose heating energy is transferred to the melt via the walls of the immersion tube.
Um die Energieeffizienz und die Homogenität der Temperaturverteilung in der Schmelze zu verbessern, wird erfindungsgemäß vorgeschlagen, den Brenner in einem Tauchrohr anzuordnen, das in einem unteren Abschnitt mit wenigstens einer Strömungsöffnung für die Rauchgase ausgerüstet, im Übrigen aber geschlossen ausgebildet ist. Die aus der Strömungsöffnung des Tauchrohrs austretenden, als Gasblasen in der Schmelze aufsteigenden Rauchgase vergrößern die für die Wärmeübertragung zur Verfügung stehende Fläche, zugleich sorgen die in der Schmelze aufsteigenden Rauchgasblasen für eine gute Durchmischung der Schmelze und damit für eine homogene Temperaturverteilung. In order to improve the energy efficiency and the homogeneity of the temperature distribution in the melt, the invention proposes to arrange the burner in a dip tube, which is equipped in a lower portion with at least one flow opening for the flue gases, but otherwise formed closed. The emerging from the flow opening of the dip tube, ascending as gas bubbles in the melt flue gases increase the surface available for heat transfer, at the same time ensure the rising in the melt flue gas bubbles for a good mixing of the melt and thus for a homogeneous temperature distribution.
