Urea Dosing Control DieselNet

In NH 3 slip control, the role of the sensor signal is clear; urea dosing is adjusted to maintain the NH 3 slip setpoint. In ammonia coverage control, the NH 3 sensor can also be used to adapt the ammonia coverage maps. If more or less than expected amounts of ammonia are detected during ammonia coverage control, an adaption factor can be applied to the θ map to adjust it accordingly. The ...

Air Pollution Control Technology Fact Sheet

Other Considerations: Ammonia slip refers to emissions of unreacted ammonia that result from incomplete reaction of the NOx and the reagent. Ammonia slip may cause: 1) formation of ammonium sulfates, which can plug or corrode downstream components, and 2) ammonia absorption into fly ash, which may affect disposal or reuse of the ash. In the , permitted ammonia slip levels are typically …
