Accomplishements for the fiscal year are as follows: (1) Physical property characterization, including elemental analysis, ash, volatiles, moisture, sulfur and particle size determination has been accomplished for the virgin coal and two low-rank lignite slurries steam-dried at 300/sup 0/C and 330/sup 0/C. The elemental analysis, ash and moisture content have been determined for the recently obtained test slurry which was dried at 340/sup 0/F. Similar elemental and proximate analyses have been conducted for the subbituminous coal slurry provided by the Grand Forks Project Office. (2) Rheological tests using a capillary viscometer have been completed for a range of solids loadings and shear rates for the lignite slurry produced at a drying temperature of 300/sup 0/C. (3) A review of available nozzles and atomizers was conducted and several nozzles were identified for spray and combustion testing. (4) Apparatus for slurry spray characterization tests was fabricated to study techniques to isolate portions of the spray for particle size, velocity and trajectory measurements, and equipment was obtained for studies using high speed photography. (5) The reactor facility was moved and refurbished in preparation for low rank coal slurry combustion tests. (6) A sample of the test slurry dried at 340/sup 0/F was measured for solids, elemental analysis, moisture and ash content in initial characterization studies. A four drum quantity of test slurry, dried at 330/sup 0/F, was also received and samples from each container were analyzed for carbon, nitrogen, hydrogen, ash and moisture. (7) Electric coil wall heaters were fabricated from high temperature alloy wire, installed and tested on a test reactor insert.
