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. They also differ in usage from standard grade anthracite (used mainly for power generation), being employed mainly in metallurgy as a cost-efficient substitute for coke in processes such as sintering and pelletising, as well as pulverised coal injection (PCI) and direct injection into blast furnaces. They can also be used in water purification and domestically as a smokeless fuel. Both coals are fossil fuels. However, anthracite has far fewer impurities compared to bituminous coal — which makes it more likely to contaminate the air as it burns far less cleanly. anthracite".

Corresponds approximately to ASTM low volatile bituminous.

Anthracite coal is the highest-quality coal, with high carbon content and low moisture. It burns efficiently, producing intense heat and minimal smoke, making it ideal for open fires. Bituminous coal is a mid-grade coal with higher carbon content than others but produces more emissions. Choose anthracite for cleaner and longer-lasting open fires. What is anthracite coal? The two other types of coal are lignite and anthracite. Sub-bituminous coal is used primarily as fuel for steam-electric power generation. While bituminous coal is also used mainly as fuel in steam-electric power generation, it can be used for heat and power applications in manufacturing too. Hsu, Li-Yeh; Teng, Hsisheng (May 2000). "Influence of different chemical reagents on the preparation of activated carbons from bituminous coal". Fuel Processing Technology. 64 (1–3): 155–166. doi: 10.1016/S0378-3820(00)00071-0. Anthracite coal: Anthracite is the highest rank of coal. It has a bright luster and breaks with a semi-conchoidal fracture. What is Coal "Rank"? 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.Anthracite is divided by size mainly into applications that need lumps (typically larger than 10mm) – various industrial processes where it replaces metallurgical coke, and domestic fuel – and those that need fines (less than 10mm), such as sintering and pelletising. [22] From a performance and heating standpoint, anthracite is a higher quality coal for domestic, open fire heating. While harder to ignite, anthracite does burn for a longer period of time at a hotter temperature, meaning it is more effective at providing reliable warmth for your household. John Nelson, W. (October 1987). "Coal deposits of the United States". International Journal of Coal Geology. 8 (4): 357–361. Bibcode: 1987IJCG....8..355J. doi: 10.1016/0166-5162(87)90072-3.

Assess moisture content: For combustion purposes, lower moisture content is preferred as it affects the efficiency of burning. Anthracite typically has lower moisture content compared to other coal types. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), [a] in which the carbon content is between 86% and 97%. [1] [3] [4] The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. [5] Anthracite is difficult to ignite, and burns with a short, blue, and smokeless flame. Jeddi, Samir; Schönfisch, Max; Alvarez, Carlos Fernández (2019).

Why Choose Charles Swann Coal Merchants

Identify your purpose: Determine the primary purpose for which you need coal. Different types of coal are suitable for various applications, such as residential heating, electricity generation, industrial processes, or metallurgical purposes. Report of the United states coal commission.... (5 vol in 3; 1925) Official US government investigation. online vol 1-2 Less Maintenance: Anthracite coal produces less residual ash compared to bituminous coal, which means you’ll have to clean out the fireplace less frequently.
