State energy information, including overviews, rankings, data, and analyses. Steam powered trains were also powered by thermal coal. Bituminous coals are the most common fuel in the power sector. Bituminous: Containing the widest range of carbon content (45% to 86%), bituminous is mainly used as a fuel to generate electricity, though some is used as coking coal to produce steel. J. Kraushaar, R. Ristinen. High-volatile bituminous coal is classified on the basis of its calorific value on a moist, ash-free basis (ranging from 24 to 33 megajoules per kilogram; 10,500 to 14,000 British thermal units per pound), while medium-volatile and low-volatile bituminous coals are classified on the basis of the percentage of fixed carbon present on a dry, ash-free basis (ranging from 69 to 78 percent for … Come test out some of the products still in development and let us know what you think! http://commons.wikimedia.org/wiki/File:Bituminous_Coal.JPG, http://energy.about.com/od/Coal/a/Bituminous-Coal.htm, https://energyeducation.ca/wiki/index.php?title=Bituminous_coal&oldid=7854.

West Virginia leads production, followed by Kentucky and Pennsylvania. Subscribe to feeds for updates on EIA products including Today in Energy and What's New. Bituminous coal (in Indiana), contains between 69% & 86% carbon by weight Sub-bituminous coal contains less carbon, more water & is a less efficient source of heat Lignite coal, or brown coal, is a very soft coal … Anthracite: Anthracite has the highest carbon content (86% to 97%).

Financial market analysis and financial data for major energy companies. Subbituminous coal, also called black lignite, generally dark brown to black coal, intermediate in rank between lignite and bituminous coal according to the coal classification used in the United States and Canada. The character of their volatile matter is more complex than that of anthracites and they are higher in calorific value. Regional energy information including dashboards, maps, data, and analyses. Sign up for email subcriptions to receive messages about specific EIA products. First, this type of coal produces excessive amounts of smoke and soot and its high sulfur content contributes to acid rain through the release of sulfur oxides (SOx). In many countries subbituminous coal is considered to be a brown coal.Subbituminous coal contains 42 to 52 percent carbon … What You Should Know About Metallurgical Coal, Air Pollution Causes, Effects, and Solutions, Carbon Tax, Its Purpose, and How It Works, How Air, Water, and Plastic Pollution Affect the Economy, Nuclear Power in America, How It Works, Pros, Cons, and Its Impact, Climate Change Facts and Effect on the Economy, Six US Natural Resources That Boost the Economy, Deforestation Facts, Causes, Effects, and What You Can Do, Greenhouse Gas Effect on the Economy and You, Plastic Pollution’s Effect on the Economy and Environment, Trump vs. Obama on Their Economic Policies, President Donald Trump's Policies and Economic Plan. 1100 - 1800 (kg/m 3) Typical Bulk Density of Coal.

Tools to customize searches, view specific data sets, study detailed documentation, and access time-series data. EIA's free and open data available as API, Excel add-in, bulk files, and widgets. Sometimes called "black lignite," sub-bituminous coal is not stable when exposed to air; it tends to disintegrate. The coal's sulfur content is generally less than 2 percent by weight. Lignite coal is typically comprised of coal deposits which have had the least amount of heat, pressure, and time to develop. Sub-bituminous coal is noncoking and contains less sulfur but more moisture (approximately 10 to 45 percent) and volatile matter (up to 45 percent) than other bituminous coal types.
