Background

At present, a quartz fiber burner is generally a linear fire row, and when quartz fibers are produced, the quartz fibers corresponding to each flame hole are drawn downwards to the central position below the burner, are firstly bundled and then are wound and collected. The number of flame ports of the burner must be limited within a certain range, that is, the length of the burner cannot be too long, if the burner is too long, when a plurality of corresponding quartz fibers are bundled, the larger the bundling angle (i.e., the maximum bundling angle) of the quartz fibers corresponding to the flame ports which are farther from the horizontal distance of the bundling point is, the longer the length of the quartz fibers is correspondingly drawn, and when the longer quartz fibers are bundled with the middle shorter quartz fibers, the tension of the quartz fiber bundle is uneven, which frequently causes 'filament flying', and the tensile force bearing performance of the quartz fiber bundle is greatly influenced.

Further, the burner tubes are joined end to end.

Further, the burner tube body is circular or polygonal.

Further, the polygonal burner tube body is a regular polygon.

Further, the beam concentration point is disposed below a central axis of the burner tube body.

Further, the combustor body is C type, U type, E type, S type, "king" font, "8" font or "2" font.

Furthermore, the central line or the central line connecting line of the burner tube body arranged on the flame port is in a plane.

Further, the flame ports are positioned on the outermost or innermost pipe wall of the burner pipe body.

Further, the gas inlet is far away from the flame opening.

By adopting the technical scheme, the invention has the beneficial effects that: the invention changes the traditional mode that the flame ports are horizontally arranged in a straight line on the burner, on the premise of the same number of flame ports, the flame ports are arranged in a plurality of directions in the same horizontal plane, for example, one area is formed in a rectangular coordinate system in the horizontal plane for arrangement, the arrangement mode can be regular, such as round, rectangular, triangular and the like, and also can be irregular, such as E-shaped, 8-shaped and the like, correspondingly, the burner pipe body also adopts a corresponding shape, the bundling point is arranged at the position of one center below the flame ports, so that the distance from each bundling point is as close as possible, the maximum bundling angle of the flame ports with the same number can be reduced, the phenomenon of 'flying silks' can be reduced as much as possible, the tensile force bearing performance of the drawn quartz fiber bundle can be improved, and the product quality can be improved, meanwhile, on the premise that the maximum bunching angle is fixed, the number of flame ports which can be arranged on the combustor can be further increased, the number of quartz fibers which are drawn at one time is increased, and the production efficiency of products is improved.
