A proven and cost-effective method of recovering energy for a district or local heating grid is achieved by condensing the water in flue gases. The amount of energy recovered depends on the district heating water temperature, and can be improved by using a heat pump, which can increase recovery by approximately 5 percent.

Flue gas condensation

Sweden and Denmark are considered world leaders in this type of energy efficiency improvement, with international interest in the process growing. This is partly a result of the EU's standards for energy-efficient waste incineration. A condensation system may enable an installation to meet the level requirements of the R1 factor. Flue gas condensation systems also reduce emissions, increase fuel flexibility and have the potential to reduce chemical usage and thus the amount of residual products. 

Condensate water is treated in our water treatment processes to reach purity levels of drinking water quality. Our condensing scrubbers are fitted with tower packing and droplet separators in ADIOX^® dioxin separation material to eliminate dioxin problems. 

Our flue gas condensation solutions include:

• Condensing scrubbers 
  
  
• Metallic condensers 
  
  
• Water treatment 
  
  
• Heat pumps 
  
  
• Chillers 
  
  

Absorption technology

Proven Results & Experience

• More than 35 installations firing waste or biofuels feature our flue gas condensation systems
  
  
• First installations in the 1980s are still in operation today
  
  

Conversions, upgrades and optimizations are carried out in order to ensure optimum efficiency for the customers’ equipment and to meet the demands of stricter environmental legislation. We offer service agreements for preventive maintenance including guaranteed call-out service to avoid unexpected stoppages. Our service organization also takes on installation, commissioning and servicing of absorption chillers.
