Profile Testing Improves Dryer Section Diagnostics, 1990 Papermakers Conference Proceedings
G. Walter Rosenberger, Jeffrey R. Reese--Techniques are now available to measure complete cross-machine profiles of dryer can surface temperatures and dryer pocket humidities. The measurements can be related to reel moisture profiles to determine whether problems originate in the dryer section. Problems with dryer drainage, pocket ventilation, and hood air flows can be identified and corrected.
