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 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 last quarter of 1982 characterization of Kentucky No. 11, Illinois No. 6 and Upper Freeport Indiana Co. Pennsylvania in Task 2 were completed. Combustion tests on the same three coals were performed and the deposits formed were analyzed as part of Task 3 and 4. Washability of tests on Upper Freeport Indiana Co. Pennsylvania coal was completed and analysis of the size and gravity fractions was begun as part of Task 5.
