  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.

  • Ammonia (NH3) Slip Measurement with Continuous Emissions

    Apr 13, 20203. Direct Measurement with Tunable Diode Laser. There’s a relatively newer method for measuring NH3 that has addressed some of the major issues with other NH 3 approaches. TDL uses a near-IR tunable diode laser absorption spectrometer to measure NH 3 in a process gas.. This is an in-situ measuring device meaning it measures directly in the stack or duct.
