Abstract
This project is designed to develop a family of novel NO{sub x} control technologies, called Second Generation Advanced Reburning (SGAR), which has the potential to achieve 90+% NO{sub x} control in coal fired boilers 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 O.l x lO{sup 6}Btu/hr Optimization Studies; Task 1.4 1.0 x 10{sup 6} Btu/hr Process Development Tests; Task 1.5 Mechanism Development and Modeling; and Task 1. 6 Design Methodology and Application. The fourth reporting period (July 1 - September 30, 1996) included both experimental and modeling activities. The bench scale CTT experiments (Task 1.3) were completed. The 1 MMBtu/hr Boiler Simulator Facility (BSF) was prepared for the test program and experiments were conducted using natural gas (NG) as main and reburing fuels (Task 1.4). A few preliminary tests were also performed with coal firing. The results have been reduced and are reported. Initial experimental data were obtained on reactions of sodium promoters (Task 1.2) at the University of Texas in Austin (UT). The kinetic model was extended to include reactions of sulfurmore » and sodium (Task 1.5). « lessKeywords
