Abstract
An oxidation furnace for the oxidative treatment of fibers having a housing which is gas-tight, apart from passage openings for the fibers, inter alia. A process chamber is located in the interior of the housing. Deflecting rollers guide the fibers through the process chamber in a serpentine manner so that the fibers lie next to one another as a fiber carpet which spans a plane between opposite deflecting rollers. An atmosphere-generating device can generate a hot working atmosphere and includes a blowing device with at least one outlet window through which a hot working atmosphere can be blown into the process chamber between two adjacent planes of the fiber carpet (). The working atmosphere is guided into the process chamber by a flow guiding system. The flow guiding system includes exchangeable flow guiding elements with flow passages which can be detachably and/or movably mounted on the blowing device, before the outlet window.
