Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...Coal explained. Use of coal. In 2020, about 477 million short tons (MMst) of coal were consumed in the United States. On an energy content basis, this amount was equal to about 9.2 quadrillion British thermal units (Btu) and to about 10% of total U.S. energy consumption.
