Energy Savings at PM Vacuum Systems

Introduction

During last five years I have been working a lot with energy saving prjects at paper industry.

Short desktop studies have been carried out for over 100 paper machines. Conclusion is, that energy savings can be achieved at more than 50 % of these machines. Estimated theoretical cumulative total saving potential is about 35 MW.

Felt Conditioning

Typically efficiency improvements can be achieved at felt conditioning of  printing and writing paper machiens.

Future actions and needs

All invesments at paper industry are today difficult to get through, even if pay-out times could be relatively short. Benchmarking is often the easiest method to esimate possible energy saving potential.

Thus now looking for ways to identify the right mills, where profitable improvements could be done. Please compare to the benchmarkng data.
