Double louver damper

Basic data:

Plant: Power station
Country: Germany
Investor: RWE- STEAG AG, Essen
Dimensions:  6780 x 5390 mm x 2400 mm

Problem:

RAUMAG – JANICH secured an order from RWE- STEAG AG, Essen, on behalf of their powerstation at Voerde, for the supply of two double louver dampers, ND 6780 x 5390 mm, as a replacement of two existing dampers of another supplier. The existing dampers were equipped with a multitude of blades, internal bearings, ceramic sealing strips and tapered seal landing bars. The Customer wished to improve operation and sealing efficiency.

Solution:

We replaced previous dampers with new louvre dampers with eccentrically supported, full span blades and the metal elastic NICROFLEX sealing system.

Results:

The support of the blades made them easier to operate, as expected. Moreover, equipped seals provide 100% shut off according to UVV regulations.
