Ammonium sulfate (AS) is of interest as an additive in stationary combustion plants for the simultaneous control NOx (through selective noncatalytic reduction, SNCR) and deposition corrosion sulfation alkali chlorides). The SNCR performance ammonium was evaluated through experiments a laboratory-scale flow reactor. Experiments with 5 10 wt % aqueous solutions, corresponding to AS/NO ratios abov...
