  • Patent number: 9328460
    Abstract: The invention relates to a method and to a device for drying a fibrous web wherein the traveling fibrous web is acted upon by steam and hot, moist air in the region of a preceding drying zone and is then fed to the preceding drying zone of a downstream drying zone comprising a drying cylinder and a hood allocated thereto. Hot air is taken out of the hood allocated to the drying cylinder of the downstream drying zone. To create at least a portion of the steam for the preceding drying zone, condensate and/or fresh water occurring in the drying cylinder of the downstream drying zone is heated by the hot air taken out of the hood by means of a first heat exchanger. Alternatively or additionally for creating at least a portion of the hot, moist air for the preceding drying zone, the hot air taken out of the hood guided through the first heat exchanger is fed to the preceding drying zone.

  • Patent number: 9228779
    Abstract: Infrared air float bar for use in floating and drying a continuous planar web of a material in a dryer. Direct radiated or reflected infrared electromagnetic energy from an infrared light source in a removable channel assembly accelerates drying, or evaporation of solvents, or curing of web material passing in proximity to the bar, either by infrared electromagnetic energy, or in combination with convention airflow. The infrared source is cooled by pressurized air passing through an interior portion of the removable air bar channel assembly, and the air is further conducted into fluid contact with the web in an air gap between the emitter and web to promote convective heat transfer and to contribute to the air pressure field supporting web flotation. The removable channel assembly is configured for replacement of the infrared emitter and to allow the setting of the pressurized cooling air flow to the optimum level.
