Flue Gas Condensation

Flue Gas Condensation Heat Recovery in flue gas cleaning parts become essential for plant efficiency. Performant flue gas condensation units proposed by LAB are possible to combine to all existing or new flue gas cleaning process.

It is performed by condensing the water in the flue gases and transfer the recovered heat to the district heating network.

Condensing units can be implemented in different ways:

  • in combination to a polishing scrubber with an external heat exchanger
  • direct condensation using a plates or tubes condenser

Assisted condensation with use of heat pumps (absorption or compressor type) and chilled water loop is also included in LAB portfolio and references.

For Biomass plants, heat recovery is maximised by combination of flue gas condensation and humidification of combustion air.
