Coal Drying Improves Performance and Reduces Emissions
Lignite and subbituminous coals from the western U.S. are attractive fuels for power plants, due their low cost and emissions. However, lignite and PRB coals typically contain high amounts of moisture and/or ash. When high moisture coals are burned in utility boilers, about 7 percent of the fuel heat input is used to evaporate fuel moisture.

What are the types of coal? U.S. Geological Survey
There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are:Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
