AirEcotube (Primary method for NOx and CO emission reduction)

AirEcotube is based on the use of special perforated pipes called Ecotube® for air injection to the boiler at very high speed in order to optimize the combustion process and emission reduction of NOx and CO.


Due to AirEcotube technology the following advantages can be achieved:


  • Two combustion zones in boiler (λ<1 and λ>1),
  • Higher turbulence,
  • Even temperature distribution,
  • NOx reduction of about 50%,
  • CO reduction below 55 mg/Nm3,
  • O2 to level around 2-3%,
  • Combustion in a whole chamber volume (Volumetric Combustion).
