Smokeless coal is more efficient than a conventional open coal fire indoors because the high working temperature is released into the room as infrared radiation, as can be judged by the bright red color of a mature fire. The hot gases produced are lost up the chimney, thereby reducing efficiency just as in an open coal fire.
The following table lists the coal mines in the United States that produced at least 4,000,000 short tons of coal.. According to the U.S. Energy Information Administration (EIA), there were 853 coal mines in the U.S. in 2015, producing a total of 896,941,000 short tons of coal.
The coal in this field is a low volatile coal, known as "smokeless" coals. [1] The seams of coal that have been mined include Sewell, Fire Creek, and Beckley. This is very high quality bituminous coal rated at approximately 15,000 BTU (16,000 kJ).
Coal plants have been closing at a fast rate since 2010 (290 plants closed from 2010 to May 2019; this was 40% of the US's coal generating capacity) due to competition from other generating sources, primarily cheaper and cleaner natural gas (a result of the fracking boom), which has replaced so many coal plants that natural gas now accounts for ...

The coal seams—Pocahontas No. 3, No. 4, No. 6, and No. 11—are some of the best coal to be found in the world, and are rated at 15,000 Btu/lb (35 MJ/kg). [ 3 ] This operation, replete with beehive coke ovens, eventually spawned the Pocahontas Fuel Company , which operated mines in Virginia at Boissevain and Amonate , and in West Virginia at ...

The Coalite plant near Shuttlewood in 2006. Coalite is a brand of low-temperature coke used as a smokeless fuel. The title refers to the residue left behind when coal is carbonised at 640 °C (1,184 °F). It was invented by Thomas Parker in 1904. In 1936 the Smoke Abatement Society awarded its inventor a posthumous gold medal. [1]
