  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    Introduction. The ammonia (NH 3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH 3 analyzers that perform measurements indirectly, NH 3 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.
