Laboratory tests were made to determine the chemical analysis of this fuel and the remaining ash, its viscosity-temperature relationship, comparative burning characteristic by use of thermogravimetric analysis (TGA) and its grindability. The test coal was fired in the atomized form employing a conventional type burner employed for No. 6 fuel oil (bunker C). Firing tests were also made in a small laboratory furnace using the fuel in the pulverized form. The results and conclusions are: (1) based on results of both the proximate and ultimate analyses, this material appears very similar to a high volatile bituminous coal except for a reduction in sulfur and ash content; (2) ash analyses indicate a tendency for selective removal of the various constituents, i.e., ash was high in sodium and titanium compared to the normal range of coal ashes; and (3) thermogravimetric analyses indicate ignition characteristics similar to a high volatile bituminous coal. However, for complete combustion or burnout this fuel appears to more closely resemble a semi-anthracite.
