Coal | Energy4me
Types of Coal. There are four main categories for coal based on the amounts of carbon it contains and the heat energy it can produce. The bituminous and anthracite types of coal typically contain more heat-producing energy. Lignite: Over time, heat and burial pressure turn peat into lignite. Lignite is somewhat light in color, soft and crumbly.

The ranks of coal (from most to least carbon content) are as follows: anthracite, bituminous coal, sub-bituminous coal, and lignite. The coal with the highest carbon content is the best and cleanest type of coal to use. As you move down the coal rank the heat given out decreases and the dirtiness of the fuel and moisture content increases. Used ...
What is coal? | U.S. Geological Survey
Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, …
