This research project is for the development of a technical and economical feasible process for drying and stability fine particles of high-moisture subbituminous coal. Research conducted in this quarter focused upon thermogravimetric analysis (TGA) of both feed coals; continuation of the bench-scale IFB drying experiments; and initiation of the characterization of the products from the bench-scale drying experiments to determine their moisture reabsorption, dustiness, and spontaneous ignition properties. Thirty 4-hr and six 12-hr bench-scale IFB drying tests were conducted this quarter making a total of forty-one 4-hr (19 using Eagle Butte feed coal and 22 using Usibelli feed coal) and six 12-hr (3 using each feed coal) tests conducted thus far. IFB reactor slopes of 3, 6, 9, 12, and 15 degrees were investigated for each feed coal. During the tests using Eagle Butte coal, gas-to-solids ratios ranging from approximately 0.7 to 9.7 lb/lb (kg/kg) and average IFB reactor temperatures ranging from approximately 370 to 700/degree/F (188 to 371/degree/C) were tested. 5 refs., 41 figs., 7 tabs.
