Optimizing Steam Use in the Dryer Section, 2006 Papermaker’s Conference
The dryer section is the largest steam user in a paper mill. The majority of steam energy is used to evaporate water as heat is transferred to the paper through the dryer shell. Steam consumption can be well above good performance levels depending on how the dryer steam and air systems are designed and operated. Many opportunities exist to reduce steam consumption by optimizing the dryer system. The first step in optimizing dryer steam consumption is to benchmark steam use against production data. Benchmark values are established for dryer consumption, system losses, and dryer air systems. This paper presents practical methods to determine savings opportunities and introduces a framework for defining an energy efficient dryer system. Case histories are provided to show examples how steam savings can be achieved through system optimization.
