HOW TO IMPROVE THE PAPER MACHINE PERFORMANCE BY COMBINING DRYER SECTION SURVEY AND COMPUTER SIMULATION

The continuously increasing paper machine speeds and widths have contributed to the growing importance of dryer section runnability. To obtain an optimal way of operating the dryer section, the papermakers can have access to dryer section surveys performed by machine manufacturers and suppliers of ventilation equipment and dryer fabrics. In the last years also the use of computer simulation has increased. It strengthens the reliability of given recommendations and multiplies the benefits gained from the survey by enabling the valuation of even completely new running situations.
