Show CONCLUSIONS The pilot-scale combustion work has provided excellent screening and trend data. Modeling can be used to compliment and extend the results for the design of retrofit 10w-NOx systems. The limitations of pilot-scale testing are not thought to be significant with regard to unforeseen problems at scale up. Physical and numerical flow modeling provide further input to design for mixing phenomena not duplicated at the pilot-scale level. ACKNOWLEDGMENTS The authors would like to acknowledge the guidance of previous and current contract managers, Angelos Kokkinos and David Eskinazi at EPRI and John Pratapas at GRl. We also would like to acknowledge the demonstration site project managers and engineers, Robert Newell and Steve Gebhan at Wisconsin Power and Light and Charles Bellanca, Scott Miller, and Hao Duong at Dayton Power and Light. In addition, we acknowlege the hard work of contributing B&W pilot-scale test technicians, Eugene Stoffer and Victor Burgess. We would also like to thank the many B&W modelers for their input to these programs including Woodrow Fiveland, Richard Wessel, Chris Latham, Bill Oberjohn, George Watson, Ray Kim, and Vince Belovich. Finally, we acknowledge the previous and current B&W project and technical managers, Al LaRue, Bruce Janssen, Tony Yagelia, Gerry Maringo, and Tom Laursen.
