Using vacuum in various paper machine positions is expensive. In fact, vacuum is one of the top three energy consumers in a paper mill. By using vacuum only in the most critical positions, you can fully benefit from a more efficient nip dewatering strategy and save energy. By measuring the water flow online accurately enables you to optimize vacuum levels and not overdo them. Heat recovery provides another way to save energy.
Using recovered heat instead of primary energy sources, for example, to warm up shower waters or dryer hoods allows you to expect major cost savings.
By optimizing your papermaking process, you can save energy up to 30-70% as well as improve runnability and paper quality.
Switch over from an LRP to an EP Turbo Blower
Did you know that the EP Turbo Blower is at least 15-30% more efficient than a new liquid ring pump (LRP)?
And as an LRP wears down, this difference grows. In typical rebuild projects, 40-60% energy savings have been achieved. Process optimization and lower energy consumption start with the EP Turbo Blower. This completely water-free vacuum solution offers significant heat recovery potential for paper machines. Mills have reported that vacuum system optimization with variable speed and capacity turbo blowers have saved them up to 2,000 kW. However, to save energy maximally up to 30-70% takes more than just switching over from LRP’s to turbo blowers. You need other optimization measures, too.
