Industrial Applications

Double Flap Dampers in steel and sponge iron plants control material discharge and gas isolation at critical hopper outlets and duct branch points.
Application 1

Blast Furnace Dust Catcher Discharge

Controls gravity discharge of coarse dust from BF gas dust catchers while maintaining gas-tight seal against pressurized blast furnace top gas.
Application 2

Sinter Plant De-Dusting Hopper

Discharges collected iron-bearing dust from sinter plant de-dusting hoppers for recycling back to the sinter mix without gas leakage.
Application 3

DRI Product Discharge Isolation

Isolates hot DRI pellet discharge chutes from the reactor vessel, preventing process gas escape during product extraction and transfer.
