  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    Process Overview. The NH 3 gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas, as well as to increase the dust collection efficiency of the dust collector (ESP) and prevent erosion. Excess NH 3 injection increases the running cost and the residual NH 3 amount, resulting in the generation of a foul odor. Therefore, the NH 3 concentration in the stack flue gas is measured, controlled, and monitored.

  • 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. The TDLS8000 Laser Analyzer is the solution to all these problems. | Yokogawa Electric Corporation
