Abstract

The invention relates to a steam blower box for the application of steam onto a material web passing by, for example onto a paper web that is to be dewatered and is passing through the press section of a paper-manufacturing machine. The steam blower box extends, transverse to the web travel direction, over the entire web width and comprises a plurality of zone chambers, that are arranged side by side over the web width and are covered by a perforated steam exit panel. Each zone chamber is connected to a steam source via a control valve of its own. The steam exit panel can be removed for purposes of cleaning the zone chambers. Each of the zone chambers comprises a perforated panel insert which is likewise removable.
