Voith High Efficiency HM Rotor Energy Data, A Repulper Rotor Design Case Study
Abstract
A recently completed
demonstration project, funded partly by
the Wisconsin Focus on Energy
program and Wisconsin Public Service
Corporation, shows the effectiveness of
an energy efficient repulper rotor
design compared with that of a
conventional rotor. We conducted a
demonstration to measure the
performance and energy consumption
of the energy efficient virgin pulp
repulper of Wausau Paper in
Rhinelander, Wisconsin. This paper
describes the demonstration setting,
shows the analysis, and discusses the
results.
Careful monitoring of the batch
repulping operation gave us a very
good picture of the energy savings. We
monitored the energy use and impact
on pulp quality under the following
three conditions:
1. The existing conventional
repulping blade (HOG rotor)
2. A new conventional repulping
blade of the same style (spare
HOG rotor)
3. A new energy efficient
repulping blade (HM rotor)
The HM rotor, a tall, swept-back blade
design, has been engineered to provide
effective turbulence of the fiber
suspension and maximum rotor-fiber
contact while consuming low
horsepower.
