FGD Inlet & Outlet Isolation
A matched set of raw gas, clean gas and bypass gates that lets the absorber be opened while the unit stays on load.
Solutions, by duty position
A damper is only right when it matches the duty at its own position. These are the five application problems we are asked about most often, and how we answer them.
Boiler Duct Isolation
Air preheater, ID fan and stack isolation using double-shaft gates sized to the duct section.
Air & Gas Flow Regulation
Linear-characteristic dampers with ball-jointed linkage for stable control loops.
Desulfurization Corrosion Protection
Material and lining selection for the wet, chloride-bearing sections of the FGD duct.
Custom Non-Standard Duct Components
Design and fabrication of non-standard dampers, gates, supports and flue components to drawing.
How we work
From enquiry to dispatch
1. Duty review
We read the duct section, temperature, pressure difference and gas composition, and confirm the duty position.
2. GA drawing
A general arrangement drawing is issued for approval, including flange drilling and actuator mounting.
3. Fabrication
Material certificates, qualified welding and dimensional checks are recorded against the order.
4. Test & ship
Blade travel and seal tested with the actuator fitted, limit switches set, then export packing.
