The purpose of this present research program is to investigate the details of soot formation from liquid fuel droplets and to provide information on methods of minimizing soot formation during synthetic liquid fuels combustion under conditions which minimize the formation of nitric oxides. The program comprises two main tasks, Fuel Screening Studies and Flame Studies. The purpose of the first task is to investigate the impact of fuel properties on particulate production, to establish the importance of droplet size and examine atomizer effects, and to develop techniques for surrogate fuels production. In the second task, fundamental details of soot formation from synfuel droplet combustion will be investigated in variable slip velocity configurations. During the past quarter, no new experimental efforts have been initiated in the Fuel Effects (Subtask 1.1) and Blending Studies (Subtask 1.3) subtasks. Efforts on these tasks are to be resumed and completed once the final test fuel (H-coal) and detailed analyses for all fuels have been received. Work has, however, been started on the preparation of hardware for the 1 MW (3 x 10/sup 6/ Btu/hr) pilot-scale studies of Task 1.5. In the Task 2-Droplet Studies phase of the program, all experimental efforts in the slip flow reactor system have been completed and reported. In the current period, efforts have concentrated on the construction and preliminary checkout of the opposed-jet diffusion flame and microspray reactors. These systems will form the basis of the second phase of the droplet study where conditions more representative of turbulent diffusion flames are to be investigated.
