Benefits:
Safe limit compliance
NOx reduction <200 mg/Nm³ (0.15 lb/MMBtu) possible
Avoidance of investment in SCR
Low slip at low reagent consumption
Reduced operating costs = fast amortization
Upgradable with PiT Navigator to reduce primary NOx
Features:
Software
Adaptive and self learning software; permanent dynamical optimisation through autarkic learning and therefore saves the manual adaption to process changes
Autonomous process exploration within given limits; as a process expert constantly working on process optimisation
Internal prediction of future developments at NOx, temperature, coating etc.
Online-CFD: Continuous on-line description of temperature
distribution by dividing the rising duct into many small volume
elements.
(Download 6 MB Video with
explanation from a large scaled PF power boiler, duration 5 minutes;

16 MB example video showing developement over 15 hours in approx. 2
minutes)
Online-calculation of the ideal spray amount (considering the future and current levels of NOx, O2, temperature, deposition rate and slip)
Hardware
Multi level SNCR
Single lance control
Additional temperature measurement of different depth in the refractory material of the rising duct to estimate the current coating in the riser duct
Modularity: Possibility to upgrade to PiT Navigator to reduce the primary
NOx by up to 150mg/Nm³
