When SNCR is used, BAT is to achieve efficient NOx reduction, while keeping the ammonia slip as low as possible, by using the following technique:
| Technique | |
|---|---|
| a | To apply an appropriate and sufficient NOx reduction efficiency along with a stable operating process |
| b | To apply a good stoichiometric distribution of ammonia in order to achieve the highest efficiency of NOx reduction and to reduce the NH3 slip |
| c | To keep the emissions of NH3 slip (due to unreacted ammonia) from the flue-gases as low as possible taking into account the correlation between the NOx abatement efficiency and the NH3 slip |
