The Stora Enso Anjala PM2 drying section runnability was optimized in two steps. In 2009, runnability problems of the double felted section were eliminated with machine geometry modification and stabilizing technology tailored for the area. In the second step, in 2010, runnability of the single felted section was optimized.”The problems because of poor runnability are eliminated after the web stabilizing projects in single and double felted sections. We have now more stable sheet run, and the drying section runnability enables also higher speed,” says Antti Outinen, Production Manager, Stora Enso Anjala PM2.At Arjowiggins Dalum mill in Denmark, significant energy savings and higher production was achieved on PM7 after the drying section optimization project. The project included modern heat recovery, hood exhaust units, condensate and steam coils, supply air fans, pocket ventilation technology and web stabilizing technology.“Now 65 percent of the PM7 heating energy is recovered for district heating and hood supply air year round. The machine speed has increased by about 20 percent,” says Claus Christiansen, Production Manager, Arjowiggins Dalum, PM7./KB
