Abstract: A method for producing quartz glass cylinders includes producing soot bodies using depositing burners to deposit SiO2 particles for mass deposition on a rotating substrate and vitrifying the soot bodies to form quartz glass cylinders. Prior to producing the soot bodies, the following steps are carried out: producing first and second test soot bodies, determining the density distribution of the first test soot body in the axial direction; vitrifying the second test soot body to generate a test quartz glass cylinder; determining the mass distribution of the test quartz glass cylinder in the axial direction; and setting the mass deposition of SiO2 particles to be deposited as a function of the axial mass distribution of the test quartz glass cylinder. As such, the mass distribution of the produced and vitrified soot bodies is improved and/or made more homogeneous relative to the axial mass distribution of the test quartz glass cylinder.

Abstract: Common solar radiation receivers are equipped with a chamber for transmission of an operating gas which is directed along to an absorber for solar radiation for thermal absorption. The absorber has a dome-shaped entry window made of quartz glass, wherein the inner side facing the absorber assumes a nominal interior temperature Ti of at least 950° C. during proper use, preferably at least 1000° C., whereas the outer side facing away from the absorber is exposed to the environment and subject to risk of devitrification. The invention relates to modifying the known solar radiation receiver so that a high absorber temperature can be set and thus a high efficiency of the solar thermal heating is enabled, without increasing the risk of devitrification in the region of the outer side of the entry window.
