Energy Savings through Optimized Refining, 2006 Papermaker’s Conference
The cost of energy for refining on a typical fine paper machine can exceed $1.0 million per year. A typical linerboard machine can exceed $3.0 million per year. By using a system-wide optimization strategy to match hydraulic capacity, plate patterns, and alloy to the needs of the paper machine, significant savings can be found. In addition, the proper mechanical condition, use of new technologies and upgrades can also reduce energy requirements. Overall, 10% to 20% energy savings can be realized through an optimized refining strategy.
