Temperature, velocity and Species Profile Measurements for Reburning in a Pulverized, Entrained Flow, Coal Combustor
Measurements of effluent NO{sub x}, CO, and O{sub 2} have been obtained for various reburning locations in the controlled profile reactor. the location of the reburning zone and tertiary air zone have been varied to find an optimal location for detailed reburning profile measurements. No{sub x} reduction of greater than 70% has been seen with natural gas injection in and just below the primary combustion zone. Strategic injection of the natural gas for reburning reduces the total No{sub x} reduction capability of reburning. Modeling efforts continue in trying to match the modeling solution to the detailed baseline data taken in previous measurement. The use of more accurate measured boundary conditions did not appear to improve the model predictions greatly but the use of more detailed turbulence models was found to improve the predictions, the predictions are still far from matching the combustion measurements.
