F27D 99/00 - Subject matter not provided for in other groups of this subclass
An oxidation furnace for the oxidative treatment of fibers, which, comprises a process chamber arranged inside a housing, a blowing device arranged in the center of the process chamber, a suction device arranged in the two opposite end regions of the process chamber, at least one ventilator that circulates the hot air through the blowing device, the process chamber and the suction devices, and at least one heating device arranged in the flow path of the hot circulated air. The blowing device comprises a plurality of vertically interspaced blowing boxes comprising an inlet, and, on opposite sides, outlets for the hot air. Two stacks of vertically interspaced blowing boxes may be provided, said blowing boxes being interspaced one behind the other in the direction of movement of the fibers, and/or the built-in boxes in a stack comprise at least one additional outlet in the upper side and the lower side, for hot air.
F26B 13/00 - Machines or apparatus for drying fabrics, fibres, yarns, or other materials in long lengths, with progressive movement
F27B 9/28 - Furnaces through which the charge is moved mechanically, e.g. of tunnel type Similar furnaces in which the charge moves by gravity for treating continuous lengths of work
F27D 7/00 - Forming, maintaining or circulating atmospheres in heating chambers
An oxidation furnace for the oxidative treatment of fibers, especially for producing carbon fibers, which comprises a process chamber arranged inside a housing, a blowing device for hot air, at least one suction device arranged in an end region of the process chamber, at least one ventilator that circulates the hot air through the blowing device, the process chamber and the suction device, and at least one heating device arranged in the flow path of the hot circulated air. The suction device is formed from a plurality of vertically interspaced suction boxes. Said boxes have at least one outlet for the hot air, and at least one inlet for hot air, communicating with the process chamber and arranged in the outward-facing side of the suction boxes, that is the side that is at a distance from the center of the process chamber.
