Abstract

The detection of gaseous ammonia in the flue gas of biomass combustion systems is becoming increasingly important due to stricter legislation. The optimization of an existing sensor principle showed significant improvements in ammonia sensitivity in comparison to the original sensor. In further measurements in the flue gas of a wood combustion, the cross sensitivities to other components turned out to be very low. So, a high accuracy in the determination of the ammonia concentrations could be achieved in comparison to an FTIR spectrometer.
