The purpose of a flue gas cleaning system is to reduce atmospheric emissions of substances hazardous to the environment and health. This includes e.g. heavy metals, dioxins and substances that cause acidification and eutrophication. Because many of the substances are toxic and carcinogenic, it is important to reduce their emissions. The acidification of forests and lakes has been reduced substantially by removing sulfur dioxide and oxides of nitrogen from flue gas.

Babcock & Wilcox Vølund AB offers both subsystems and fully assembled installations for cleaning flue gases generated by the incineration of e.g. hazardous municipal and industrial waste and the combustion of biofuels. Metal, chemical and process industries are also numbered among our customers. Together with our owner, Babcock & Wilcox Vølund A/S, we are able to provide turnkey installations from fuel feed to smokestack (see NextBAT® below) and with exceptional flue gas cleaning where required.

Our flue gas cleaning systems are customized to meet our customers' specific requirements. We often combine wet and dry flue gas cleaning. We place great emphasis on ensuring our installations easily exceed emission standards according to applicable EU directives and also anticipated future standards.

Products

More than 40 incineration lines are in operation with flue gas cleaning systems from Babcock & Wilcox Vølund AB. We have also installed our ADIOX® dioxin removal technology in more than one hundred incineration lines. We upgrade existing installations to meet increasingly restrictive environmental standards and deliver our unique, compact systems to new installations. Flue gas cleaning systems are often integrated with flue gas condensation for energy recovery in multi-stage scrubber systems.

We provide the following principal processes, of which many can be combined to advantage:

We have developed many, unique technologies:

  • ADIOX® – dioxin removal using carbon-doped plastics in scrubbers and absorbers.
  • MERCOX™ – oxidation and removal of mercury in wet scrubbers.
  • CUTNOX® – reduction of NOx formation in grate furnace systems using air-water jets.
  • Multi-stage scrubbers – compact, multi-functional units with small footprints.
  • Sulfur recirculation – reduction of high temperature corrosion by returning sulfur to the furnace.
  • Wet electrostatic precipitators – separation of dust and particulates in a wet scrubber.

NextBAT®  ̶  from crane to stack

In collaboration with our owners, Babcock & Wilcox Vølund A/S, we have developed a concept for turnkey NextBAT® installations that offers exceptionally low emissions and will meet the requirements of the coming waste incineration BREF.
