From measurement to control
The system combines distributed NOₓ/O₂ measurements, ammonia-slip analysis and flow information with the plant’s ammonia-injection controls.
- Feedforward control responds to changing operating conditions.
- Closed-loop feedback coordinates total NOₓ and ammonia-slip objectives.
- Zone balancing and self-learning logic support adjustment of the ammonia injection grid.
Define the control boundary
Review the existing plant controls, dosing equipment, measurement positions and commissioning plan together. The final control architecture and equipment are project-specific.
Operating benefits depend on baseline conditions and commissioning. The website does not turn source-case savings into a guaranteed result.
