Five Damper Gate Selection Mistakes That Show Up Two Years Later
None of these mistakes look like mistakes at the quotation stage. All of them cost real money once the unit has run for a couple of years.
Technical news and application notes
Sealing systems, material selection, maintenance practice and selection guidance — written by the people who build the gates.
Mounting Orientation: Why a Damper That Works Sideways Fails Upright
Shaft horizontal or vertical, actuator above or below, housing on the pressure side or the suction side. Three choices that decide how long the gate…
Electric or Pneumatic: Choosing the Actuator Before It Chooses for You
Speed, fail position, torque at speed and what the plant already knows how to maintain. The four questions that settle the argument.
How Much Sealing Air Does a Damper Gate Actually Need?
The 0.5 % rule of thumb, when it is wrong, and the measurement that proves the seal on the day the permit is signed.
Coating Systems for FGD Dampers: Where They Work and Where They Do Not
Glass-flake epoxy, rubber lining, thermal spray and solid alloy compared on the duty each one is actually good for.
How Often Should a Flue Damper Be Inspected?
A schedule built from duty rather than from a manual: what to check monthly, what to check at every outage, and the three measurements worth…

Where damper noise comes from, why partly open is the worst position, and the three fixes that actually work.
The Technical Documents a Damper Tender Actually Needs
A checklist of the drawings, certificates and calculations that separate a bid an engineer can evaluate from one that has to be guessed at.
Material Selection for Flue Gas Damper Gates and Where It Matters
The gate is the bridge between the boiler, the FGD absorber and the wet ESP. Because the three positions see completely different gas, they cannot…
