Planned results:

  • plant level: plant modul/system components
  • data level: test series/-program
  • publications: scientific paper (ISI, peer-reviewed)


The use of biogenic residues in combustion plants and the combustion of biogas results in increased nitrogen oxide emissions, which require mitigation. The research project intends to develop novel sensors and sensor principles for the measurement of NOx and NH3, which can be applied for the optimal control of SCR systems and the monitoring of biomass plants.


  • Development of NH3 sensor for use in SCR systems at biomass plants
  • Practical evaluation on plants operated with biogenic residues
  • Development of sensor technology for measuring the NH3 loading of SCR catalysts
  • Research of the method for loading measurement at SCR-system on a biogas CHP plant
