| Abstract: | This report describes the work done in the third year of the project {open_quotes}Investigation of Transport Processes Involved in FGD{close_quotes}. The objectives of this five year plan of study is to experimentally obtain a basic understanding of (1) turbulent flow structure of the mixing zone and its influence on particle dispersion, (2) the effect of particle loading on turbulent properties and mixing, (3) the effect of jet entrainment, (4) water spray-sorbent interaction, sorbent wetting and mixing, (5) investigate the flow field where certain ratios of jet velocity to flue gas velocity result in regions of negative flow and define onset of negative flow (6) sorbent reactivity in mixing zone and (7) effect of particle agglomeration. In the first two years of the project a sorbent injection facility which can simulate the conditions encountered in COOLSIDE set up was designed and built. Non-intrusive laser based diagnostic tools PDA/LDA was used for flow characterization of particle laden jet in cocurrent flows. All tasks for third year were addressed. The accomplishments for the third year include the following. For the investigation of Lime Laden Jet Flow, since no existing technique was capable of providing the simultaneous measurement of irregular shaped particle size and velocity, a new technique, TTLDV which utilizes the transit time in LDV measurement volume and the LDV velocity measurements to obtain simultaneous particle size and velocity measurements was developed. Better Sorbent Injection Methods and Optimized Injection Schemse were investigated. Progress was made in the development of Technique to Study Particulate Droplet Interactions, the task was not completed because of difficulties encountered due to differences in the refractive index of glass beads and water droplets. The investigations of flow reversal resulting from spray jet cocurrent flow interactions was completed. |
