Abstract
A method, system and apparatus is disclosed for drying a wet web quickly and efficiently on the surface of a steam heated drying cylinder in a continuous papermaking process. A steam-heated drying cylinder having an exterior surface is rotated under a drying hood adjacent the exterior surface of the drying cylinder. The hood comprises a drying zone of heated air, with nozzles adapted to supply hot air streams into the drying zone. A wet web is adhered to the drying cylinder and rotated through the drying zone of the hood. Then, hot air streams are directed from the nozzles upon the wet web. A hot air stream is provided from a nozzle at a lead angle that deviates from perpendicular between about 3 and about 30 degrees, in a lead direction towards the downstream end of the web drying process.
