  • 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.
