PSE&G, Wahlco, and Siemens have successfully demonstrated the technical feasibility of a Post Combustion NO{sub x} Reduction System on a 321 MW net coal-fired utility boiler at PSE&G`s Mercer Station Unit 2. The program featured a selective catalytic reduction (SCR) reactor in a horizontal flue gas duct and an air heater SCR (AHSCR). Predicted performance of the In-Duct SCR was confirmed. The AHSCR was shown to be an effective means to enhance overall system performance as compared to an In-Duct SCR alone. Selective Non-Catalytic Reduction (SNCR) was also tested in combination with the SCR/AHSCR system using aqueous ammonia as a common reduction agent. Ammonia based jet mixing SNCR and the use of an ammonia injection grid was found to be the operation of choice in the NH{sub 3} based SNCR/SCR Hybrid NO{sub x} reduction system.
