The five parent coals ear-marked for this study have been characterized. These coals include (1) a Texas (Wilcox) lignite; (2) a Montana (Rosebud) subbituminous; (4) an Alabama (Black Creek) high volatile bituminous; and (5) a Pennsylvania (Buck Mountain) anthracite. Samples for analyses were prepared in accordance with the ASTM standard (ASTM D 2013-72). The following ASTM analyses were performed on each coal: proximate, ultimate, higher heating value, Hardgrove grindability index, ash fusibility, and ash composition. Additionally, the flammability index (FI) of each coal was determined in an in-house apparatus. The FI is indicative of the ignition temperature of a given fuel on a relative basis. The combustion kinetic parameters (apparent activation energies and frequency factors) of Montana subbituminous and Pennsylvania anthracite chars have also been derived from data obtained in the Drop Tube Furnace System (DTFS). This information depicts the combustion characteristics of these two coal chars. 1 ref., 5 figs., 4 tabs.
