This research project is for the development of a technically and economically feasible process for drying and stabilizing of fine particles of high-moisture subbituminous coal. Research activities were initiated with efforts concentrating on characterization of the two feed coals: Eagle Butte coal from AMAX Coal Company's mine located in the Powder River Basin of Wyoming; and coal from Usibelli Coal Mine, Inc.'s mine located in central Alaska. Both of the feed coals are high-moisture subbituminous coals with ''as received'' moisture contents of 29% and 22% for the Eagle Butte and Usibelli coals, respectively. However, physical analyses of the crushed coal samples (--28-mesh particle size range) indicate many differences. The minimum fluidization velocity (MFV) of the feed coals were experimentally determined. The MFV for --28-mesh Eagle Butte coal is approximately 1 ft/min, and the MFV for --28-mesh Usibelli coal is approximately 3 ft/min. 2 refs., 16 figs., 3 tabs.
