Drying Performance and Fabric Tension - Mill Trials, 2003 Spring Technical Conference Proceedings
Dryer fabric tension is a major factor affecting drying performance yet information on the subject is limited and much of what appears in journals and standards is dated. A recent laboratory study showed the positive effect on drying rate of operation at elevated dryer fabric tension. In this paper, the results from mill trials on different paper grades (news, fine and linerboard) are presented which support the findings of the lab trials and show that significant improvements in drying capacity can be achieved by operating dryer fabrics at tensions higher than those commonly used by industry.
