STEAG Energy Services (SES) was commissioned to control the existing SNCR system using the IT solution PiT Navigator SNCR. The aim was to meet the statutory daily and half-hour limit values of NOx and NH3 and to reduce the cost of the reducing agent consumption.

Services by SES: use of the existing SNCR system; connection to the control system for reading and writing signals; implementation of the complete control incl. pre-control of the reducing agent flow based on a NOx-prognosis; automatic selective control of all SNCR lances.

Benefits: reliable compliance with the limit values; reduction of reducing agent cost; fully automatic control of the SNCR system without manual intervention.
