Boiler Feedwater & Condensate Filtration

Returned condensate and make-up feedwater carry iron-oxide (corrosion products) and suspended particulate that foul boiler internals and reduce heat-transfer efficiency. High-flow filtration captures this particulate load before it reaches the boiler, protecting an expensive asset.

Where in the process

On the feedwater line and on condensate return, upstream of the boiler / deaerator. It removes particulate corrosion products; it is not a demineralisation stage.

What goes wrong without adequate filtration

  • Iron-oxide and corrosion products that foul boiler internals
  • Reduced heat-transfer efficiency and higher fuel cost
  • Media that break down at elevated condensate temperature
  • Unplanned boiler outages driven by particulate carry-over

How it works

  1. 1

    Filter feed and return

    The element sits on the feedwater line and condensate return, upstream of the boiler / deaerator — the last particulate barrier before the boiler.

  2. 2

    Capture iron-oxide load

    Temperature-appropriate media remove iron-oxide corrosion products and suspended solids from hot condensate and make-up water.

  3. 3

    Run long between outages

    High dirt-holding extends run time so the filter suits continuously running steam plant with few interventions.

  4. 4

    Protect the boiler

    Clean feed keeps boiler internals and heat-transfer surfaces clean, protecting efficiency and the asset.

Typical filtration requirements

  • Capture of iron-oxide particles and suspended solids
  • Media suited to elevated condensate temperature
  • High dirt-holding for extended runs between outages
  • Low pressure drop to protect feed-pump duty

Why high-flow wins here

1Large elements handle full feed / return flow with few housings

Selection & sizing factors

Operating temperature
Hot condensate narrows the media choice — media are selected to be rated for the operating temperature.
Boiler cleanliness target
How clean the boiler feed must be sets the rating — finer for high-pressure or sensitive plant.
Feed / return flow
The feed and return flow sizes element and housing so full flow is covered with few housings.
Particulate loading
The iron-oxide and solids load sets the dirt-holding needed for a long run between outages.

Sizing & selection

Feedwater and condensate filtration typically targets fine-to-mid particulate, with media chosen for the operating temperature. The rating follows how clean the boiler feed must be. Tell us your steam-plant duty and temperature for a recommendation.

The right housing for this solution

A feedwater / condensate housing must suit the operating temperature and pressure of the steam plant, so material and rating are chosen for that duty. We size the housing to the feed / return flow and supply the temperature-appropriate high-flow elements. Use the housing configurator to specify a feedwater or condensate vessel.

Operational impact

Clean boiler feed preserves heat-transfer efficiency and lowers fuel cost
Fewer change-outs suit continuously running steam plant
Protected boiler internals mean fewer unplanned outages
One source for element and housing simplifies steam-plant support

Frequently asked questions

Does this replace demineralisation?

No. This is particulate removal (iron oxide, suspended solids). Dissolved-ion control still relies on demineralisation / condensate polishing resin where required.

Can the media handle hot condensate?

Yes — we select media rated for the operating temperature of your condensate. Share the temperature and flow.

Why filter condensate at all?

Returned condensate carries iron-oxide corrosion products picked up in the steam/condensate loop. Filtering it stops that particulate from fouling boiler internals and heat-transfer surfaces.

What rating is typical for feedwater?

Feedwater and condensate filtration usually targets fine-to-mid particulate; the exact rating follows how clean the boiler feed must be. Tell us the plant and we recommend one.

The right solution for your process?

Tell us your flow rate, medium and target rating — we recommend the element and, if required, the matching housing.
