Dresden Papier PM 4 Projects Boosts Environmental
 Print this article | Send to Colleague
Dresden Papier, Germany, last summer completed the installation of a new vacuum system for the wire and press sections of its PM 4 in Heidenau, and optimized the heat recovery system to improve environmental performance and increase energy savings. Germany-based Voith Paper was commissioned to handle this project. With the exception of construction work, Voith was responsible for the complete scope of supply and services.
Dresden Papier based its investment decision on an extensive pre-engineering of the existing vacuum system and a balancing of the entire PM and building ventilation technology. The paper mill wanted to record and implement both the economy and the energy saving potential. The examination was performed by Voith.
As Voith explains, a vacuum blower system ensures high thermodynamic efficiency, allowing at the same time power input depending on the air requirements at the paper machine. The hot exhaust air produced can be used for hood supply-air heating through heat exchangers to reduce steam consumption there. Another important aspect in terms of environmental protection is the fact that this technology does not consume any fresh water as conventional systems do. Hence, operating costs are also decreased, and maintenance is optimized due to the reduced number of vacuum generators.
Currently, PM 4 in Heidenau is producing 45,000 metric tpy of uncoated and coated nonwoven wallpaper base and the mill is thus the world's largest producer in this product segment. Dresden Papier GmbH is a subsidiary of Canadian Fortress Paper, Ltd.
