Description

Dave Osborne (ed), The Coal Handbook: Towards Cleaner Production: Volume 1: Coal Production Elsevier, 2013 Bituminous coal is its carbon content, which ranges from 45% to 86%. This makes it a relatively high-grade fuel compared to other types of coal. In terms of energy output, bituminous coal produces more heat per unit than lower-grade coals.

In the United States, bituminous coal is further divided into subranks based on its heating value and fixed carbon content.The Coal Region of Northeastern Pennsylvania in the United States has the largest known deposits of anthracite coal in the world with an estimated reserve of seven billion short tons. [7] China accounts for the majority of global production; other producers include Russia, Ukraine, North Korea, South Africa, Vietnam, the United Kingdom, Australia, Canada, and the United States. Total production in 2020 was 615 million tons. [8] The Groundhog Anthracite Deposit, located in British Columbia, Canada, is the largest previously undeveloped anthracite deposit in the world. It is owned by Australian publicly listed company Atrum Coal and has 1.57 billion tonnes of high grade anthracite. [30] Australian in situ coal resources" (PDF). Geosciences Australia. 2012 . Retrieved 13 November 2021.

Coal deposition was interrupted by the Permian-Triassic extinction event, [48] but resumed later in the Permian. Extensive bituminous coal deposits of Permian age are found in Siberia, east Asia, and Australia. [49] These include the Minusinsky coal basin in Siberia, [50] the Queensland, Bowen, and Sydney Basins in Australia, [51] and the extensive bituminous coal reserves of China.

High grade (HG) and ultra high grade (UHG) anthracite are the highest grades of anthracite coal. They are the purest forms of coal, having the highest degree of coalification, the highest carbon count and energy content and the fewest impurities (moisture, ash and volatiles). Sahney, S.; Benton, M.J.; Falcon-Lang, H.J. (2010). "Rainforest collapse triggered Pennsylvanian tetrapod diversification in Euramerica". Geology. 38 (12): 1079–1082. Bibcode: 2010Geo....38.1079S. doi: 10.1130/G31182.1. From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern US, until it was supplanted by oil-burning systems, and more recently natural gas systems. Many large public buildings, such as schools, were heated with anthracite-burning furnaces through the 1980s.

Bibcode: 2005Gbio....3...13C. doi: 10.1111/j.1472-4669.2005.00043.x. S2CID 129219852.Bituminous coal is used primarily for electrical power generation and in the steel industry. Bituminous coal suitable for smelting iron (coking coal or metallurgical coal ) must be low in sulfur and phosphorus. Is anthracite coal clean? a b Mobley, R. Keith (2001). "Coal and ash". Plant engineer's handbook. Boston: Butterworth-Heinemann. p.21/339. ISBN 9780080539041 . Retrieved 10 November 2021. Anthracite Coal, is more normally known as “hard coal.” Anthracite coal is a highly-carbnated fossil fuel that will generate the highest heat of all the fossil fuels availabe and the low sulfur content in Anthracite makes it an extremely clean-burning fuel.

Environmental impact: If sustainability and environmental impact are crucial, look for cleaner-burning coal with lower emissions. Arigoni, Ashley; Newman, Alexandra; Turner, Cameron; Kaptur, Casey (October 2017). "Optimizing global thermal coal shipments". Omega. 72: 118–127. doi: 10.1016/j.omega.2016.12.001. Structurally, anthracite shows some alteration by the development of secondary divisional planes and fissures so that the original stratification lines are not always easily seen. The thermal conductivity is also higher; a lump of anthracite feels perceptibly colder when held in the warm hand than a similar lump of bituminous coal at the same temperature. [5]Nowak, Grzegorz J. (April 2004). "Facies studies of bituminous coals in Poland". International Journal of Coal Geology. 58 (1–2): 61–66. Bibcode: 2004IJCG...58...61N. doi: 10.1016/j.coal.2003.08.006.
