Temperature, velocity and species profile measurements for reburning in a pulverized, entrained flow, coal combustor. Semi-annual report, October 30, 1995--April 30, 1996
Data for mean velocity and temperature have been obtained over a baseline matrix operating conditions for pulverized coal without reburning. The data show the reactor to be symmetrical about the axial centerline. Effluent NO{sub x} data have been seen to correlate with measured and modeled results of flow patterns within the reactor. At low swirl the fuel jet creates a downward flow at the centerline with some upward recirculation at the perimeter of the reactor near the walls. This recirculation pattern reverses as swirl is increased, changing the flame from a long toroidal shape to a flat annulus. The NO{sub x} data show a local minimum at a swirl number of 1.0 which may be primarily the result of the direction and magnitude of the recirculation zone. Gas species and coal char burnout data have begun but have not yet been completed. Velocity data and modeling results have been used in the process of validating the comprehensive combustion code and in designing the reburning hardware. The details concerning storing and delivering the reburning fuel (natural gas) have been completed and the fabrication of the hardware is underway.
