Industrial Applications

Parallel Dampers in power plants provide continuous combustion air and flue gas modulation, enabling load-following boiler operation and fan energy optimization.
Application 1

FD Fan Discharge Control

Modulates forced-draft fan discharge volume to maintain optimum combustion air supply across boiler load range from 30% to 100% MCR.
Application 2

ID Fan Inlet Regulation

Controls induced-draft fan inlet flow to maintain furnace negative pressure, preventing puffing and ensuring stable combustion.
Application 3

PA Fan Volume Modulation

Regulates primary air fan output to coal mills, adjusting pulverized fuel transport air velocity for varying coal quality and boiler load.
