Flue Gas Condensing and Heat Recovery

A_Keuruu_F0009 768x432.jpg

There is a lot of energy in flue gas due to the water (30–60%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmet’s advanced flue gas condensing technology, you can recover this energy and use it for example to increase district heat capacity or save fuel.

Up to 30% more energy from fuel through flue gas condensation

Low additional investment costs

High availability and low maintenance costs

Valmet offers different technologies for heat recovery

  • Tube condenser
  • Condensing scrubber
  • Combination of these two (a pre-scrubber and a tube condenser)

To boost heat recovery even more, it is possible to add either a combustion air humidifier or a heat pump to either of the solutions. Valmet also offers condensate treatment solutions with which will treat condensed water to raw water quality or even to demineralized water quality for the boiler and thus create a truly zero-emission plant.

Each condensing solution will be tailored to meet your specific fuel and flue gas condensing needs.
