Advanced Dryer Controls

Control systems that optimize process variables offer an effective way of reducing energy consumption, increasing productivity, and improve the quality of industrial processes. They also hold a significant potential for paper machines. Dryer Management System™ control software is one such system offering advanced control of dryer system set points and process parameters to reduce steam use and improve productivity (Kramer et al., 2009. p.100).

Energy Savings Potential

In a study performed in a US based mill a potential to reduce steam consumption by around 2 tons per hour was identified with the use of the Dryer Management System™ software tool (Kramer et al., 2009. p.101).

Costs

Corresponding energy cost savings of 2 tph steam reduction were $360,000 annually (2006 dollars). Payback period has been estimated as 3 years based on energy savings alone. This period excludes productivity benefits. In another US based mill annual savings of $263 000 were observed due to energy savings enabled with the use of advanced control systems for paper machines (Kramer et al., 2009. p.101).
