Ibbenbüren power plant lowers energy needs with 18%
The Ibbenbüren power plant in North Rhine-Westphalia, Germany, has lowered its energy-needs with 18%, and still relies on an optimal air flow. Key to this result are 3 ZB VSD centrifugal blowers from Atlas Copco. They are used to generate oxidation air for the flue gas desulphurization installation.
Blowers combining efficiency and performance
The turbo installation has not only lowered energy needs by 18%, but offers optimal reliability. The oil-free blowers hardly require maintenance due to their motor with a permanent magnet.
Delivering exact amounts of air
Flue gas desulphurization is very complicated. Too little air is just as bad as too much. The speed-controlled ZB 130 VSD blowers a-enable us to save 18.1% in energy compared to earlier set-ups.
Blower precision and control
The performance of the ZB turbos were actually 8 to 9 percent higher than what Atlas Copco promised.
Mathematically proven gains
A mathematician from the company came to the conclusion that the Atlas Copco machines, based on their components and design, needed less energy than the others that were being looked at. The result – 18% less power consumption in the REA – has since confirmed RWE expectations, plus a little extra: "The performance of the ZB turbos were actually 8 to 9 percent higher than what Atlas Copco promised," Uwe Jäkel says. "This is not only economical, but also good for the environment,” Manfred Hollekamp said. “At the end of the day, the power plant uses less coal per kilowatt hour produced.”
