Sufficient amount of coal powder was filled in the container and compacted. Excess coal powder was scraped carefully from top of the vessel with the sharp edge of a spatula, and the weight of the coal powder in the container was taken. The bulk density of the sample was determined by dividing the sample weight by container volume.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
