Test TP-013-3 was conducted to evaluate gasifier operability with various coal feedstocks. The primary goal of this test was to explore the feasibility of feeding coal directly to the gasifier without the benefit of pretreatment or devolatilization. The candidate coals chosen were a non-caking Wyoming sub-bituminous coal, a mildly-caking Indiana No. 7 coal from the Minnehaha mines and a highly-caking Pittsburgh seam coal from Consolidation Coal's Champion facility. The free-swelling indices of these three coals were 0, 2 and 8, respectively. The Pittsburgh coal had a Gieseler plasticity of 28,000 ddm. A total of 75 hours of gasifier operation was logged in this test and 50 tons of fuel were processed. Reactor temperatures were held between 1720/sup 0/F and 1770/sup 0/F. The heating value of the product gas fell in the range of 69-129 Btu/scf. The ash particles discharged from the agglomerator were angular in shape with ash contents of 37 percent to 69 percent.
