Solid residue from roasting coal in a coke oven; used principally as a fuel and in the production of steel. Formally used also as a domestic fuel in Appalachian coal-mining areas
{i} ® Coca Cola, brand name of a popular carbonated soft drink which was first invented in 1886 in Atlanta (Georgia, USA) by a pharmacist named Dr. John Stith Pemberton (originally intended as a patent medicine)
In general, coke is made from bituminous coal from which the volatile constituents are driven off by baking in an oven at temperatures as high as 2,000 degrees Fahrenheit, so that the fixed carbon and ash are fused together Coke is hard and porous and is strong enough to support a load of iron ore in a blast furnace It is used both as a fuel and a reducing agent in smelting iron ore in a blast furnace
Coke is the residue formed when coal is heated in the absence of air It is primarily carbon with mineral matter and some residual volatile material (1)
Carbonizing coal made in oven by driving off volatile elements It is a hard porous substance that is principally pure carbon In blast furnaces, coke helps generate the 3000 F temperatures and reducing gases needs to smelt iron ore
clean, light fuel produced when coal is strongly heated in an air- tight oven Coke contains 90% carbon and makes an useful domestic and industrial fuel (used, for example in the iron and steel industries and in the production of town gas)
Coal from which most gases have been removed by heating It burns with intense heat and little smoke, and is used as an industrial fuel A solid residue left after the distillation of petroleum or other liquid hydrocarbons
Coke is the same as cocaine. A trademark used for a soft drink. See Regional Note at tonic. To convert or be converted into coke. To affect or intoxicate with cocaine. Solid residue remaining after certain types of coals are heated to a high temperature out of contact with air until substantially all components that easily vaporize have been driven off. The residue is chiefly carbon, with minor amounts of hydrogen, nitrogen, sulfur, and oxygen. Also present in coke is the mineral matter in the original coal, chemically altered and decomposed. The gradual exhaustion of timber in England had led first to prohibitions on cutting of wood for charcoal and eventually to the introduction of coke. Thereafter the iron industry expanded rapidly and Britain became the world's greatest iron producer (see Abraham Darby). The crucible process (1740) resulted in the first reliable steel made by a melting process. Oven coke (about 1.5-4 in., or 40-100 mm, in size) is used in blast furnaces to make iron. Smaller quantities of coke are used in other metallurgical processes (see metallurgy), such as the manufacture of certain alloys. Large, strong coke, known as foundry coke, is used in smelting. Smaller sizes of coke (0.6-1.2 in., or 15-30 mm) are used to heat buildings
A hard, dry carbon substance produced by heating coal to a very high temperature in the absence of air Coke is used in the manufacture of iron and steel
The basic fuel consumed in blast furnaces in the smelting of iron Coke is a processed form of coal About 1,000 pounds of coke are needed to process a ton of pig iron, an amount which represents more than 50% of an integrated steel mill's total energy use Metallurgical coal burns sporadically and reduces into a sticky mass Processed coke, however, burns steadily inside and out and is not crushed by the weight of the iron ore in the blast furnace Inside the narrow confines of the coke oven, coal is heated without oxygen for 18 hours to drive off gases and impurities
A hard, dry carbon substance produced by heating coal to a very high temperature(1000 degrees celsius) in the absence of air Coke is used in the manufacture of iron and steel

A solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatile constituents are driven off by baking in an oven at temperatures as high as 2,000 degrees Fahrenheit so that the fixed carbon and residual ash are fused together Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace Coke from coal is grey, hard, and porous and has a heating value of 24 8 million Btu per short ton
