COAL DUST DAMPER TYPE KSK-HLK 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. The damper type KSK-HLK comes with an additional hot-air connection. In closed position of the main damper blade hot air injected ensures automatic cooling and cleaning from remaining dust at the burner port. As a result the burner is protected against illegal high temperatures and the boiler is protected against explosion.
