Diverter / Flap Dampers
Diverters /Flap Dampers are primarily used in gas turbine applications with heat recovery steam generators (HRSG). A diverter damper is designed with one inlet and two outlets. The outlets are normally at right angles from each other. The blade pivots from one end rotating 90 degrees to close off one of the two outlets. This system always allows for an escape route for the flue gas, therefore protecting any upstream equipment from bottlenecking the turbine. Diverters can be supplied in a low leak or zero leak application. They are perfect for clean applications that require low-pressure drop and good isolation.
