These terms can cause confusion because many of the principal methods and much of the equipment used for cleaning coal have significant overlap in the particle size ranges they can treat. …

Coal Preparation Equipment

Coal preparation is an important aspect of coal handling. When coal leaves a plant's coal handling system, it generally is sent to one of two places. Depending on the design of the plant, the coal may go directly to a boiler furnace to be burned, or it may go through coal processing equipment, such as a pulverizer, before it is burned.

Coal Processing and Use for Power Generation

The use of coal is negatively perceived, since the use of fossil fuels in power generation and other industry sectors contributes significantly to the CO 2 emissions worldwide. Of the main fossil fuels, coal has the lowest H:C ratio, and consequently coal has the highest CO 2 footprint per unit of combustion energy produced. Coal also …
