The objective of this program is to examine slags formed as a result of firing coals with varying concentration levels, size, distribution, and orientation of pyrite with regard to mineral matter in the coal in a laboratory furnace. The program tasks are: (1) selection of eight candidate coals; (2) chemical characterization of the coal samples and identification of the pyrite size, distribution, and orientation with respect to other mineral matter and concentration levels; (3) testing of the candidate coals in a laboratory furnace; (4) chemical and physical characterization of the slag and fly ash samples created by the impurities in the coal sample; (5) influence of coal beneficiation on furnace slagging; and (6) analysis of data and identification of parameters influencing the contribution of pyrite to slagging problems. During the second quarter of 1983, characterization of Kentucky No. 9 was completed in Task 2. A combustion test on the same coal was conducted, and the deposits formed were analyzed as part of Tasks 3 and 4. Analysis of washabiltiy tests on Upper Freeport coal from Indiana County in Pennsylvania, was completed, and washing of a 2000-lb sample was begun. 23 figures, 11 tables.
