تعريف alevli kömür في التركية الإنجليزية القاموس.

(Jeoloji) bituminous coal

A shiny black coal that develops from deeply buried lignite through heat and pressure, and that has a carbon content of 80% to 93%, which makes it a more efficient heating fuel than lignite

A dense coal, usually black, sometimes dark brown, often with well-defined bands of bright and dull material, used primarily as fuel in steam-electric power generation, with substantial quantities also used for heat and power applications in manufacturing and to make coke Bituminous coal is the most abundant coal in active U S mining regions Its moisture content usually is less then 20 percent The heat content of bituminous coal ranges from 21 to 30 million Btu per ton on a moist, mineral-matter-free basis

The most common coal It is dense and black (often with well-defined bands of bright and dull material) Its moisture content usually is less than 20 percent It is used for generating electricity, making coke, and space heating

The most common type of coal with moisture content less than 20% by weight and heating value of 10,500 to 14,000 Btus per pound It is dense and black and often has well-defined bands of bright and dull material

the most abundant type of coal, which has a high heating value and usually a high sulfur content Illinois coal is bituminous coal

Soft coal

A general term descriptive of coal intermediate in rank between sub-bituminous and anthracite and including metallurgical coals Low and medium volatile bituminous coals are ranked by their carbon content, while high volatile bituminous coals are ranked by their heating value

Bituminous coal is the most common coal It is dense, black, often with well-defined bands of bright and dull materials Its moisture content usually is less than 20 percent It is used for generating electricity, making coke and space heating

A dense, black, soft coal, often with well-defined bands of bright and dull material The most common coal, with moisture content usually less than 20 percent Used for generating electricity, making coke, and space heating See coal

Bituminous coal is the most common coal It is dense, black, often with well defined bands of bright and dull materials Its moisture content usually is less than 20 percent It is used for generating electricity, making coke, and space heating The contents of subbituminous and bituminous coal range from 16 to 24 million Btu per ton and from 19 to 30 million Btu per ton, respectively

A mineral coal with a high percentage of volatile matter that burns with a smoky yellow flame. Also called soft coal. or soft coal Most abundant form of coal. It is dark brown to black and has a relatively high heat value. Widely abundant and with the broadest range of commercial uses, it has long been used for steam generation in electric power plants and industrial boiler plants. Certain varieties are also used to make coke, a hard substance of almost pure carbon that is important for smelting iron ore. One major problem is that burning large quantities of bituminous coal that has a medium to high sulfur content contributes to air pollution and produces acid rain. See also subbituminous coal

Middle rank coal (between subbituminous and anthracite) formed by additional pressure and heat on lignite Usually has a high Btu value and may be referred to as "soft coal "

Soft coal with a heat content of 24 to 30 million BTUs per ton, and a high percentage of volatile material

rich in tarry hydrocarbons; burns readily with a smoky yellow flame

{i} soft coal, mineral coal containing hydrocarbons that evaporate easily and tarry substance and burns with a smoky yellow flame

– A middle rank coal (between subbituminous and anthracite) formed by additional pressure and heat on lignite Usually has a high Btu value and may be referred to as "soft coal "

'Soft coal', containing between 15 and 50 percent volatile matter It is 'younger' and of lower heat value than anthracite It is the chief fuel in power plants that generate electrical energy with steam

a black industrial coal of higher rank than lignite and lower rank than Anthracite; sometimes called soft coal

The most common coal It is dense and black (often with well-defined bands of bright and full material) Its moisture content usually is less than 20 percent It is used for generating electricity, making coke, and space heating Comprises five groups classified according to the following ASTM Specification D388-84, on a dry mineral-matter-free (mmf) basis for fixed-carbon and volatile matter and a moist mmf basis for calorific value

The most common coal, which is dense, black and has a moisture content of less than 20% Used for generating electricity, making coke, and space heating
