摘要： The invention relates to a device for producing optically homogeneous, streak-free quartz glass bodies (11) having a large diameter comprising a furnace device (12), an inner chamber (16) with facing openings (13, 13'). In one (13) of said facing openings at least one burner (14) is provided and in the other the respective glass body (11) to be produced is located in the other facing opening (13') are movably positioned. Both said burner and said glass body are movably positioned. In the course of the production of the quartz glass body (11), a relative movement is effected place in the axial and radial direction between the burner (14) and the quartz glass body (11) in such a way that the distance from the burner outlet opening (15) pertaining to the quarz glass body (11) decreases (Fig. 3) as the distance from the burner (14) to the X-X axis of the quartz glass body increases.
