Rheological measurements for the lignite slurry (produced at 300/sup 0/C) continued for a range of solids loading values in the slurry, concentration was achieved using vacuum evaporation of the original 40/60 (lignite/water) slurry. At high shear rates, the slurry exhibited thixotropic characteristics, while at lower shear rates the behavior more closely approximated that of a Newtonian fluid. Subbituminous coal ash and moisture determination showed 5.5% ash for slurries produced at both temperatures and moisture content of the dried coals of 2% and 2.7% for 300/sup 0/C and 330/sup 0/C slurry process temperatures, respectively. Assembly and fabrication of apparatus and equipment for slurry spray tests began. Nozzle manufacturers were contacted to supply canidate nozzles for slurry spray and combustion tests. Reactor assembly and facility modifications to the slurry feed system and combustion products drainage system were also completed.
