Engineering Development of Coal- Fired High Performance Power Systems

The current computational fluid dynamics modeling technique is capable of identifying the optimal reagent injector locations for SNCR systems. However, this technique cannot quantify NOx reduction and ammonia slip. ABB carried out a research project to investigate various computational fluid dynamics (CFD) models and the chemical kinetics of nitrogen species during coal combustion. An enhanced computational model was developed by integrating CFD and chemical kinetics to predict the overall performance of SNCR systems. The model was validated using data collected from a large-scale experimental test facility. Table of
