2-way coal dust dampers

COAL DUST DAMPER TYPE KSK

Coal dust dampers are used in pipings of coal fired power plants between mills and burners. The purpose of these dampers is to shut-off individually the coal feeding line upstream the burner when the corresponding mill is out of service. The coal dust dampers are of heavy duty design with an optimised flow pattern to prevent deposit formation. In opened position the damper flap is positioned completely out of the dust stream which results in full orifice cross section for less pressure drop.

  • Reliable shut-off of the medium due to robust seat sealing system
  • Very short positioning times compared to simple knife gate vakves

OPERATION DETAILS

When in its closed position, the flap plate is pressed onto the flap seat by the drive shaft and the internal lever, ensuring dust-tight shut-off. When the flap is opened, the flap plate is moved around 90° and unblocks the entire flow cross section. In this position the flap plate does not interfere with the flow.
