Optimization of Constellation Energy’s SNCR System at Crane Units 1 and 2 Using Continuous Ammonia Measurement

Constellation Energy installed SNCR systems at the CP Crane Station, units 1 and 2. These SNCR systems use continuous ammonia slip analyzers that work on the principle of tunable diode laser (TDL) spectroscopy and provide continuous, real-time indication of ammonia slip in the duct. These analyzers facilitated optimization of the SNCR system to avoid high ammonia slip transients that are the principal contributors to downstream problems normally associated with ammonia slip.
