Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity. Most of the electricity consumed in the United States is made by burning coal.

Characterization of fly ash from coal-fired power plants

Abstract. X-ray analysis shows that mullite and silica are the major crystalline phases in fly ash. The "method of known additions" from X-ray diffraction techniques was used to calculate changes in the significant peak intensities of mullite and silica to determine their weight fractions in fly ash.

Size Distribution of Fine Particles from Coal Combustion

Measurements of the particle size distribution at the outlets of six coal-fired utility boilers showed a peak at a particle diameter near 0.1 micrometer. This submicrometer mode appears to be a general feature of coal combustion that results from a volatilization-condensation process in the boiler. At the boilers tested, the submicrometer mode contained 0.2 to 2.2 percent of the total fly ash .
