hard coal
A compact, dense, brittle rock whose color is steely or jet black; has a glassy or almost metallic luster, an uneven or conchoidal fracture and a Mohs hardness of 2 or more Joints, well developed and bedding observed in all, except small pieces Anthracite contains 85 to 99 percent carbon, 1 to 15 percent volatile material, and a small amount of clay and other ashy impurities; burns lowly with a pale, clean, blue flame and with much less smoke than from soft coal Hard coal occurs in regions where rocks haven been folded, heated, and squeezed Coal of the highest metamorphic rank, containing approximately 90% carbon
(from Greek anthrax, 'coal') hard, dense, shiny variety of coal
The highest rank of coal; used primarily for residential and commercial space heating It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter
coal with a volatile ratio equal to 0 12 or less
A hard, black, lustrous coal containing a high percentage of fixed carbon and a low percentage of volatile matter Often referred to as hard coal
highest rank of coal; developed by metamorphism of lower ranks of coal; can be referred to as "hard coal"
Hard, very pure, lustrous coal containing a high percentage of carbon anticline Strata which dips in opposite directions from a ridge or an axis
A hard, black lustrous coal, often referred to as hard coal It contains a high fixed carbon and ash content and is low in volatile matter It is the highest rank of economically usable coal The moisture content generally is less than 15 percent It is a non-coking coal Anthracite contains approximately 22 to 28 million Btu per ton
A hard, black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter
A hard, dense type of coal, that is hard to break, clean to handle, difficult to ignite, and that burns with an intense flame and with the virtual absence of smoke because it contains a high percentage of fixed carbon and a low percentage of volatile matter
A hard, black, lustrous coal containg a high percentage of fixed carbon and a low percentage of volatile matter It is often referred to as "hard coal"
A type of coal characterized by a high percentage of carbon and low percentage of volatiles, providing a high heat value Anthracite often forms as a result of metamorphism of bituminous coal
A hard coal used in the drinking water treatment process to remove particles
A hard, black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and low percentage of volatile matter
The highest grade of coal, with high heating value and generally low sulfur content
A hard, compact coal characterized by high luster and low sulphur content Anthracite is comprised of less volatile matter than bituminous coal, which provides for its nearly non-luminous flame Extensive anthracite deposits, representing the majority of U S reserves, are located in Pennsylvania and used mainly for heating homes Heat content range is over 14,000 BTU/lb
The highest rank of economically usable coal with moisture content less than 15% by weight and heating value as high as 15,000 Btus per pound It is jet black with a high luster It is mined primarily in Pennsylvania
Coal of the highest rank; it is almost pure carbon and is used mainly for home heating and cooking in some developing countries industrial purposes
A very hard coal used in water filters to remove particles
A hard, jet-black coal that develops from lignite and bituminous coal through metamorphism, has a carbon content of 92% to 98%, and contains little or no gas Anthracite burns with an extremely hot, blue flame and very little smoke, but it is difficult to ignite and both difficult and dangerous to mine
A hard coal containing little volatile matter
A hard natural coal of high luster differing from bituminous coal in containing little volatile matter
A hard, black coal containing a high percentage of fixed carbon and a low percentage of volatile matter
a hard natural coal that burns slowly and gives intense heat
A hard, black coal with high energy content, often referred to as hard coal
A hard, black, lustrous coal containing a high percentage of fixed carbon and a low percentage of volatile matter Often referred to as hard coal See coal
Anthracite is a type of very hard coal which burns slowly, producing a lot of heat and very little smoke. a very hard type of coal that burns slowly and produces a lot of heat (anthrakitis, from anthrax; ANTHRAX). or hard coal Coal containing more fixed carbon than any other form of coal and the lowest amount of volatile (quickly evaporating) material, giving it the greatest heat value. The most valuable of the coals, it is also the least plentiful, making up less than 2% of all coal reserves in the U.S., with most of the known deposits occurring in the East. Anthracites are black and have a brilliant, almost metallic lustre. Hard and brittle, they can be polished and used for decorative purposes. They are difficult to ignite but burn with a pale-blue flame and require little attention to sustain combustion. In the past they were used for domestic heating, but today they have given way to other sources of energy (e.g., natural gas and electricity)
A hard, compact variety of mineral coal, of high luster, differing from bituminous coal in containing little or no bitumen, in consequence of which it burns with a nearly non luminous flame
A form of carbon; the hardest and cleanest-burning of all the coals
{i} coal which burns with little smoke or flame
The purer specimens consist almost wholly of carbon
Also called glance coal and blind coal
