Chapter 7 COAL - Pennsylvania State University

Of the three fossil fuels in common use – natural gas, petroleum, and coal – the United States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource.

Petroleum and Coal - Purdue University

Sub-bituminous coal contains less carbon and more water, and is therefore a less efficient source of heat. Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight. The total energy consumption in the United States for 1990 was 86 x 10 15 kJ. Of this total, 41% came from oil, 24% from natural gas, and 23% from coal.

Slurry Rheology - an overview | ScienceDirect Topics

Slurry rheology is a function of particle size and its distribution, solids loading, base liquid viscosity, and particle shape; the last particularly at high shear rates. A rather complete set of experimental measurements is reported by Papachristodoulou and Trass (1984) for bituminous coal in four grades of oil, from #2 fuel oil to heavy #6 bunker oil.
