Kömür sobasıyla uyumamalısınız. Çünkü karbonmonoksit olarak adlandırılan çok zehirli bir gaz içerir. Kömür sobasıyla uyumak ölümle sonuçlanabilir. - You shouldn't sleep with a coal stove on because it releases a very toxic gas called carbon monoxide. Sleeping with a coal stove running may result in death.
Can we this quote? Walter Hines Page, Arthur Wilson Page, The World's work, Volume 38:The drop in 1918 was also a fall in the production of black coal. In other words he losses were in the best coal, the gains in the poorer coal.
An elevated railway track designed to allow material to fall freely between the rails onto the ground beneath. It is used to rapidly unload hoppers containing coal and other bulk materials.Ellis, Iain (2006). Ellis' British Railway Engineering Encyclopaedia. Lulu. page 70. ISBN 978-1-84728-643-7
A black, viscous tar made by the destructive distillation of coal (to make coke and town gas); it contains a great number of compounds including hydrocarbons and phenols; used in the preparation of medicated soap and shampoo, and industrially for the manufacture of very many products
Phenol can be obtained from coal tars by two methods : (a) Directly by separation of the product contained in this type of feedstock, at the rate of 0.5 to 1.5 per cent weight.
Administrative agency designed to integrate the coal and steel industries of France, West Germany, Italy, Belgium, the Netherlands, and Luxembourg. It originated in the plan of Robert Schuman (1950) to establish a common market for coal and steel by those countries willing to submit to an independent authority. Created in 1952, the ECSC came to include all members of the European Union. It initially removed barriers to trade in coal, coke, steel, pig iron, and scrap iron; it later supervised the reduction of its members' excess production. In 1967 its governing bodies were merged into the European Community. When the treaty expired in 2002, the ECSC was dissolved

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
A solid, brittle, more or less distinctly stratified combustible carbonaceous rock, formed by partial to complete decomposition of vegetation; varies in color from dark brown to black; not fusible without decomposition and very insoluble
A fossil fuel made of sedimentary organic rock that contains more than 40 percent carbon by weight after moisture has been removed It is formed from plant matter that decayed in swamps and bogs that has been compressed and altered by geological processes over millions of years Four main types of coal have been identified and ranked based on how much carbon and energy they contain: lignite, subbituminous coal, bituminous coal, and anthracite
A mineral form of carbon Coal is used as heat source and to produce carbon monoxide, CO, which is the primary reducing agent in the smelting of iron Anthracite, or hard coal contains 90 to 99% carbon, by mass Bitumonous and lignite coal have less carbon and more impurities and are not usually used in ironnmaking
A generic term applied to carbonaceous rocks that were formed by the partial or complete decomposition of vegetation These stratified carbonaceous rocks are either solid or brittle and are highly combustible
Coals are burning pieces of coal. It is important to get the coals white-hot before you start cooking. Solid, usually black but sometimes brown, carbon-rich material that occurs in stratified sedimentary deposits. One of the most important fossil fuels, it is found in many parts of the world. Coal is formed by heat and pressure over millions of years on vegetation deposited in ancient shallow swamps (see peat). It varies in density, porosity, hardness, and reflectivity. The major types are lignite, subbituminous, bituminous, and anthracite. Coal has long been used as fuel, for power generation, for the production of coke, and as a source of various compounds used in synthesizing dyes, solvents, and drugs. The search for alternative energy sources has periodically revived interest in the conversion of coal into liquid fuels; technologies for coal liquefaction have been known since early in the 20th century. hard coal bituminous coal soft coal Coal Measures coal mining European Coal and Steel Community subbituminous coal
A hard mineral that is flammable, and gives off heat and light It forms when decayed vegetable matter is compacted by Earth's crust From soft to hard, giving less heat to more heat, the main types are lignite, subbituminous, bituminous, and anthracite
coal is a form of stored solar energy It is created from the remains of plants that have been concentrated by heat and pressure for millions of years Coal is found in various forms or "grades," which depend on the ratio of carbon mass to energy content Represented in descending order of hardness and energy content per pound, these grades are anthracite, bituminous, sub-bituminous and lignite [return to top]
Sedimentary rock composed of the compacted, lithified and altered remains of plants Coal is a solid, combustible mixture of organic compounds, hydrocarbons, with 30 % to 98 % carbon by weight, mixed with various amounts of water and small amounts of sulfur and nitrogen compounds It is formed in several stages as the remains of plants are subjected to heat and pressure over millions of years
means combustible carbonaceous rock, classified as anthracite, bituminous, subbituminous, or lignite by ASTM Standard D388-84 found at pp 247-252 in Vol 5 05 of the Annual Book of ASTM Standards published by the American Society for Testing and Materials, 1916 Race St , Philadelphia, PA 19103
A black, or brownish black, solid, combustible substance, dug from beds or veins in the earth to be used for fuel, and consisting, like charcoal, mainly of carbon, but more compact, and often affording, when heated, a large amount of volatile matter
A black or brownish-black solid, combustible substance formed by the partial decomposition of vegetable matter without access to air The rank of coal, which includes anthracite, bituminous coal, subbituminous coal, and lignite, is based on fixed carbon, volatile matter, and heating value Coal rank indicates the progressive alteration, or coalification, from lignite to anthracite Lignite contains approximately 9 to 17 million British Thermal Unit (BTU) per ton The heat 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 Anthracite contains approximately 22 to 28 million BTU per ton
A combustible rock of organic origin composed mainly of carbon, hydrogen and oxygen with lesser amounts of nitrogen, sulphur and other elements Coal is formed from accumulated vegetable matter that has been altered by decay and by various amounts of heat and pressure
An organic mineral product resulting from the accumulation of organic material in peat bogs millions of years ago Geologic process compressed the peat into a carbonaceous material Coal varies in quality due to the inclusion of non-organic materials such as sand, silt and clay These determine the character of the coal ash and clinkers Coal also contains variable quantities of volitile hyrdocarbon compounds and sulfur This large number of variables means coal can be in any number of grades ranging from peat, to nearly pure carbon to slate Bituminous coal is a soft coal resulting from the volatile content Anthricite is hard coal that is low in volatiles See our coal and charcoal FAQ
A readily combustible black or brownish-black rock whose composition, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time
A black or brownish/black solid, combustible substance formed by the partial decomposition of vegetable matter without access to air Types of coal are anthracite, subanthracite, bituminous, subbituminous and lignite; the categories are based on fixed carbon, volatile matter, coking properties and heating value
black or blackish mineral substance formed from the compaction of ancient plant matter in tropical swamp conditions coal mining extraction of coal (a sedimentary rock) from the Earth's crust Coal mines may be opencast (see opencast mining), adit, or deepcast The least expensive is opencast but this results in scars on the landscape
