This project develops a family of novel NO{sub x} control technologies, Second Generation Advanced Reburning (SGAR), which has the potential to achieve 90+% NO{sub x} control at a significantly lower cost than selective catalytic reduction. Phase I consists of six tasks: Task 1.1, project coordination and reporting deliverables; Task 1.2, kinetics of Na{sub 2}CO{sub 3} reactions with flue gas components; Task 1.3, 20 kW optimization studies; Task 1.4, 20 kW process development tests; Task 1.5, mechanism development and modeling; and Task 1.6, design methodology and application. This third reporting period included both experimental and modeling activities. Tests continued at the Controlled Temperature Tower (CTT), and the results have been reduced and are reported. A study on high- temperature reactions of sodium promoters (Task 1.2) is underway at the University of Texas in Austin (UT). A brief literature review on high-temperature sodium reactions is included in this report. A high- temperature flow system with GC analysis was prepared at the University of Texas at Austin for the experimental program. Modeling focused on description of NO-NH{sub 3} interaction in the burnout zone.
