Anthracite

Anthracite is a hard, compact variety of coal that has a high luster and a high carbon content (typically over 90%). It is the highest rank of coal, meaning it has undergone the greatest degree of coalification (transformation from peat to coal) due to high pressure and temperature. anthracite burns with a smokeless flame and produces a high amount of heat, making it a valuable fuel source. It's typically found in areas with significant geological uplift, like the Appalachian region. Its dense structure makes it less friable than other coal types.

Anthracite meaning with examples

• In the crisp autumn air, the homeowner prepared the hearth, carefully arranging the anthracite to ensure a long, even burn throughout the evening. The fuel's intense heat output would provide warmth as the seasons transitioned. Its smokeless nature meant that indoors there'd be a clean burn. The family enjoyed the comforting glow of the anthracite fire, as they settled in for a night of storytelling.
• The railway relied on anthracite for its locomotives because it generated high amounts of energy. The trains powered by anthracite coal efficiently transported goods and passengers across the expanding nation. Its low ash content meant less frequent cleaning and thus a more reliable service schedule. The engineers favored this superior grade of coal for its dependable performance and low-smoke emissions.
• During the Industrial Revolution, anthracite fueled the booming industries. The mills depended on its potent heat and smokeless efficiency, creating the capacity for large-scale production. This coal helped shape the economic landscape. Its concentrated carbon makeup and slow burn were crucial for powering manufacturing processes. anthracite thus spurred economic growth and urban development during that era.
• Geologists studying the Appalachian Mountains found large deposits of anthracite. The geological uplift in the region caused the formation of this superior coal. Its discovery revealed a source of heat energy and led to important scientific studies. Researchers examined the strata, analyzed the coal's properties and traced its transformation over eons of geologic history.
