Temperature velocity and species profile measurements for reburning in a pulverized, entrained flow. Semiannual report, April - October 1996
The capability of LDA measurements for future reburning experiments has now been demonstrated. Measurements of mean and turbulent gas and particle velocity have been obtained using Laser Doppler Anemometry (LDA) in the near burner and quarl region of the pulverized coal reactor. The mean and turbulent velocity at the burner outlet, or top of the quarl were obtained under non-reacting conditions in order to obtain realistic boundary conditions for comprehensive combustion modeling. Also, under cold flow it was determined that little error occurred in measuring mean velocities with LDA using pulverized coal as the seed particle. Thus, for mean velocities, coal particle and gas velocities were similar. Coal particle velocity profiles were obtained at three swirls and three axial locations. Gas species, and temperature maps for the reactor have now also been completed at three swirl settings in addition to the LDA data. Gas species obtained include CO, CO{sub 2}, O{sub 2} and NO. Calibration of the HCN and NH{sub 3}measurement has been successfully completed but no measurements in the reactor have been obtained. The design and fabrication of fuel and air injectors to be used for reburning are complete. The injectors have not yet been tested.
