The results of a dryer section modification at Smurfit Kappa Wrexen, Germany, show reduced draw and a significant increase in strength properties at PM3. Drying capacity was increased due to a reduced pocket humidity level, and there is no over-drying of sheet edges. Furthermore, the equal pocket humidity has reduced the need for moisture profile control, resulting in additional direct energy savings. The ropeless tail threading improves operator safety while ensuring reliable and fast threadings. The delivery included different types of contactless RunPro web stabilizers for the pre-dryer section and geometry changes for double-tier groups and group gaps to enable good runnability even at higher speeds. On-site vacuum roll drilling work and hood air system modification were performed to maintain proper air balance. The optimization of the 0-level and dew point has increased the efficiency of the existing heat recovery system, which remarkably improved efficiency for white water heating and hall ventilation. Additionally, the pre-dryer section's ropeless tail threading and tail threading to the end of the pre-dryer to sizer ropes were upgraded with RunShooter technology. Thanks to SK Wrexen for the great cooperation during this project 🙌
