Existing NO{sub x} control technologies have limitations which may prevent them from successfully achieving commercial, cost effective application in the near future. This project develops a family of novel NO{sub x} control technologies, Second Generation Advanced Reburning (SGAR), which have a potential to achieve 90+% NO{sub x} control at a significantly lower cost than Selective Catalytic Reduction (SCR). 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, 0.1 {times} 10{sup 6} Btu/hr optimization studies; Task 1.4, 1.0 {times} 10{sup 6} Btu/hr process development tests; Task 1.5, mechanism development and modeling; and Task 1.6, design methodology and application. This second reporting period included both modeling and experimental activities. Modeling was focused on evaluation of ammonia injection into the reburning zone and on the effect of various additives on promotion of the NO-NH{sub 3} interaction in the reburning zone. First bench scale Controlled Temperature Tower (CTT) experiments have been performed on different variants of the Advanced Returning technology. The tests are continued, and the results will be reduced and reported in the next quarter.
