This project develops Fuel-Flexible Reburning (FFR), which combines conventional reburning and Advanced Reburning (AR) technologies with an innovative method of delivering coal as the reburning fuel. The overall objective of this project is to develop engineering and scientific information and know-how needed to improve the cost of reburning via increased efficiency and minimized carbon-in-ash and move the FFR technology to the demonstration and commercialization stage. The first reporting period (August 11, 2000-February 10, 2001) included experimental activities with the primary objective to characterize the impacts of reburning process parameters on NO{sub x} reduction at conditions typical of the full-scale boilers. Tests were conducted in GE EER's Boiler Simulator Facility (BSF). Tests showed that NO{sub x} reduction in basic coal reburning depends on process conditions, initial NO{sub x} and coal type. Up to 60% NO{sub x} reduction was achieved at optimized conditions
