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. Similar elemental and proximate analyses have been conducted for the subbituminous coal slurry provided by the Grand Forks Project Office. 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. Apparent viscosity comparisons with other slurries tested in an earlier program were made. A review of available nozzles and atomizers was conducted and several nozzles were identified for spray and combustion testing. Contact with manufacturers has indicated probable availability of at least one small-sized commercial nozzle for lab-scale tests. Apparatus for slurry spray characterization tests was fabricated to study techniques to isolate portions of the spray for particle size, velocity and trajectory measurements. The reactor facility was moved and refurbished in preparation for low rank coal slurry combustion tests. The first sample of the test slurry was received from the Grand Forks Project Office and solids and ash content were measured in initial characterization studies.
