Medium D: Vitrinite reflectance of 0.5 to 0.6. Corresponds approximately to ASTM high volatile C bituminous or sub-bituminous A. 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. A second peak in coal deposition began in the Cretaceous, though most of this is lower rank coal rather than bituminous. [49] In the United States, Cretaceous bituminous coals occur in Wyoming, Colorado and New Mexico. [53] [54] In Canada, the Western Canada Sedimentary Basin of Alberta and British Columbia hosts major deposits of bituminous coal that formed in swamps along the western margin of the Western Interior Seaway. They range in age from latest Jurassic or earliest Cretaceous in the Mist Mountain Formation, to Late Cretaceous in the Gates Formation. [55] The Intermontane and Insular Coalfields of British Columbia also contain deposits of Cretaceous bituminous coal. [56] Thus bituminous coal is divided into high-, medium-, and low-volatile categories based on fixed carbon content, and high-volatile bituminous coal is further subdivided by energy content.

Different types of coal are suitable for various applications, such as residential heating, electricity generation, industrial processes, or metallurgical purposes.

The Johannesburg Anthracite Company is a leading retailer of anthracite coal products for home and commercial use. We source our anthracite coal from the top suppliers across the country and deliver it around Johannesburg.

What are the Uses of Coal?

Easy to Light: Although anthracite coal can take a little longer to ignite compared to wood or other coals, it is still relatively easy to light with the right kindling and fire-starting techniques. Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation.

Medium C: Vitrinite reflectance of 0.6 to 1.0. Corresponds approximately to ASTM high volatile C to high volatile B bituminous. The belt of Carboniferous coal fields extends into central Europe, [41] and much of this is bituminous coal. Bituminous coal fields are found in Poland [42] and the Czech Republic, [43] and the Polish deposits are one of the most important of that nation's natural resources. [44] The Czech deposits have been exploited since prehistoric times. [43] The European deposits include the Coal Measures of Britain, which account for most of Britain's coal production and which are mostly bituminous coal. [45] The Westfield coal basin is the largest in Britain. [46] Other significant bituminous coal deposits are found through much of Europe, including France, Germany, and northern Italy. [47] Fushun coal mine, Liaoning, China Coal rank is based on several characteristics of the coal. The fixed carbon content refers to the percentage of the coal that is neither moisture, nor ash, nor volatile matter. When evaluated on a dry, mineral-matter-free basis, the fixed carbon content is the fraction of the coal that is not volatile organic matter. [3] An agglomerating coal is a coal that softens when heated, forming a hard, gray, porous coke that resists crushing. [4] Vitrinite reflectance is a measure of how reflective a polished surface of an average particle of vitrinite in the coal is. It is determined by how much of the carbon has condensed to an aromatic form from the heat and pressure of deep burial. [5]Winston, V.H. (February 1956). "The Polish bituminous coal-mining industry".

When it comes to combustion properties, anthracite is known for producing hot flames with very little smoke or soot. This makes it ideal for use in home heating systems where clean-burning fuel is desired. Additionally, anthracite burns slowly and steadily, providing consistent heat over extended periods. What is bituminous coal? 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. Longer Burn Time: Due to its high carbon content and low moisture content, anthracite coal burns slowly and steadily. This means you’ll spend less time refueling and tending the fire.
