Abstract (en)
[origin: WO2014048431A2] The invention relates to a dryer section for drying a web (10) of fibrous material, particularly paper, cardboard, tissue/sanitary paper, having at least one drying unit (11) for reducing the moisture content of the web (10) by means of convection drying. The drying unit (11) has at least one nozzle (12) for applying a drying fluid to the web (10), at least one discharge device (13) for the moist air produced during convection drying, and transport means for moving the web (10) relative to the drying unit (11). The drying unit (11) has at least one ultrasonic generator (15), which is arranged, for excitating vibrations in the drying fluid, in the region of the nozzle (12) in such a manner that the reduction of the moisture content by ultrasound can be supported over the entire width of the web.
