The consistent warmth produced by anthracite coal and its minimal ash waste means Welsh Anthracite is the cleanest and one of the most dependable of the smokeless solid fuels.

Coal analyses may be presented in the form of “ proximate” and “ ultimate” analyses, whose analytical conditions are prescribed by organizations such as ASTM. A typical proximate analysis includes the moisture, ash, volatile matter, and fixed carbon contents. (Fixed carbon is the material, other than ash, that does not vaporize when heated in the absence of air. It is usually determined by subtracting the sum of the first three values—moisture, ash, and volatile matter—in weight percent from 100 percent.) It is important for economic reasons to know the moisture and ash contents of a coal because they do not contribute to the heating value of a coal. In most cases ash becomes an undesirable residue and a source of pollution, but for some purposes (e.g., use as a chemical source or for coal liquefaction) the presence of mineral matter may be desirable. Most of the heat value of a coal comes from its volatile matter, excluding moisture, and fixed carbon content. For most coals it is necessary to measure the actual amount of heat released upon combustion (expressed in megajoules per kilogram or British thermal units per pound). Countries producing HG and UHG anthracite include Russia and South Africa. HG and UHG anthracite are used as a coke or coal substitute in various metallurgical coal applications ( sintering, PCI, direct BF charge, pelletizing). It plays an important role in cost reduction in the steel making process and is also used in production of ferroalloys, silicomanganese, calcium carbide and silicon carbide. South Africa exports lower-quality, higher-ash anthracite to Brazil to be used in steel-making.

(February 1956). "The Polish bituminous coal-mining industry". American Slavic and East European Review. 15 (1): 38–70. doi: 10.2307/3004277. JSTOR 3004277. 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. It commands a higher price than other grades of bituminous coal (thermal coal) used for heating and power generation.Comparatively, anthracite is a more expensive solid fuel, but there is a marked performance increase when used as a domestic fuel. Anthracite burns hotter and longer than bituminous coal, meaning that, in the long term, it’s arguably a more cost-effective solution. Ozbayoglu, G; Mamurekli, M (July 1994).

Seek expert advice: If you are unsure about the specific coal type you need, consult experts in the field, such as coal suppliers, energy consultants, or engineers, to get personalized recommendations based on your requirements. The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 26 to 33 MJ/kg (22 to 28 million Btu/ short ton) on a moist, mineral-matter-free basis. The heat content of anthracite coal consumed in the United States averages 29 MJ/kg (25 million Btu/ton), on the as-received basis (i.e., containing both inherent moisture and mineral matter). Since the 1980s, anthracite refuse or mine waste has been used for coal power generation in a form of recycling. The practice known as reclamation is being applied to culm piles antedating laws requiring mine owners to restore lands to their approximate original condition. Bituminous coal is used for the production of activated carbon. The coal is first coked, removing volatiles, then steam treated to activate it. Chemical processes for activating coke produced from bituminous coal have also been investigated.
