Second generation advanced reburning for high efficiency No. (x) control
This project is designed to develop a family of novel NO{sub x} control technologies, called Second Generation Advanced Reburning which has the potential to achieve 90+% NO{sub x} control in coal fired boilers at a significantly lower cost than SCR. The seventh reporting period (April 1 - June 30, 1997) included experimental, kinetic modeling, and engineering design activities. New experimental data for high-temperature reactions of sodium carbonate were obtained in a flow reactor at the University of Texas in Austin. The AR chemical model was used to evaluate the effect of sodium on process kinetics in the burnout zone. This study revealed that sodium affects radical concentrations which are responsible for NO{sub x} reduction under both fuel-rich and fuel-lean conditions. An engineering design study was conducted to accommodate second generation AR improvements for application in coal fired boilers. Economic and market analyses demonstrated potential advantages of AR technologies over commercial NO{sub x} control methods. All information presented in this report is in summary form since a Draft Final project report will be submitted to DOE FETC by July 31, 1997.
