Design

  • Complete plant or single part of it
  • SCR Selective catalytic reduction / highest possible conversion of NOx / catalysts for low and high dust concentration
  • SNCR Selective non-catalytic reduction / spraying of reducing agent at 900°C – 1000°C / Limited conversion rate 
  • Reduction agent storage and metering
 

Reduction agents, commercially available

  • Urea solution from tank, low cost agent
  • Ammonia water from tank,
  • Ammonia gas from casks, immediately active to react in case of high NOx-concentration and peaks
