A combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel
a coal fire
A red-hot piece of coal or other material in a fire
the glowing coals
fossil fuel consisting of carbonized vegetable matter deposited in the Carboniferous period
char: burn to charcoal; "Without a drenching rain, the forest fire will char everything"
ember: a hot fragment of wood or coal that is left from a fire and is glowing or smoldering
supply with coal
take in coal; "The big ship coaled"
Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. ...
Thomas and Friends (previously known as Thomas the Tank Engine and Friends) is a children's television series about the engines and other characters working on the railways of the Island of Sodor, and is based on The Railway Series books written by the Rev. W. Awdry.
(Coals) Embers are the glowing, hot coals made of greatly heated wood, coal or other carbon-based material that remain after, or sometimes precede a fire. Embers can glow very hot, sometimes as hot as the fire which created them. ...
A black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel; A piece of coal used for burning. ...
(Coals) The burning charcoal in the thurible.
(Coals) To see bright coals of fire, denotes pleasure and many pleasant changes. To dream you handle them yourself, denotes unmitigated joy. To see dead coals implies trouble and disappointments.
(coals (yd)) coals, pieces of coal.
FutureGen plants use coal gasification then steam reformation. Requires 1 billion tons of coal or about 1,000 275-megawatt plants with a cost of about $500 billion, or about $1 per GGE.
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. ...
The primary fuel used by integrated iron and steel producers.
Mineral generated by carbonification (distillation in absence of air) of vegetable matter, especially wood, which has built up in an anaerobic environment and has been buried under a blanket of sediment. Coal has the property of producing a highly exothermic reaction as it burns.
^ 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. ...
A fossil fuel composed mostly of carbon with traces of other elements. Coal is found in seams that can be extracted either by surface or underground mining.
Typically black in colour coal is a member of a group of easily combustible, organic sedimentary rocks composed mostly of plant remains and containing a high proportion of carbon.
Coal is a combustible mineral formed from organic matter (mostly plant material) that lived about 300 million years ago (during the Pennsylvanian Period ). During the Pennsylvanian Period, the earth was covered with huge swampy forests of giant ferns, horsetails, and club mosses. ...
a carbon-rich mineral deposit made of the remains of fossil plant life. It is first deposited as peat, but over time is buried, compressed and heated which changes it physically and chemically. ...
the fossilised remains of plant material.
A rock composed of carbonaceous material capable of being burned, usually black, derived from plants that have partially decomposed in the absence of air, under pressure and temperature.
Black or brown rock, formed under pressure from organic fossils in prehistoric times, that is mined and burned to produce heat energy.
A solid fossil fuel formed by heat and pressure from the remains of ancient plants in swampy areas
