Tandem dampers

Basic data:

Plant: FGD Plant
Country: Poland
Investor: LURGI – SMS, Denmark
Dimensions: 6000 x 8000 mm, 8000 x 5000 mm, 3070 x 2790 mm

Problem:

RAUMAG – JANICH negotiated a contract with LURGI – SMS, Denmark, for the design and supply of all necessary shut off and modulation dampers for the FGD plant of the Dolna Odra powerstation.

Solution:

We created all the tandem dampers using stainless steel. All of their blades are open and hollow.  Seals fitted throughout were of the patented NICROFLEX – HIPERFORM type.

Results:

The design reduces the cross damper pressure drop quite considerably. The choice of the resilient seals in combination with seal air make the dampers 100% gastight according to  the UVV regulations.
