Coke (fuel) - Wikipedia

Raw coke Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

12.2 Coke Production - US EPA

Coal may be added to the ovens in either a dry or wet state. Prepared wet coal is finely crushed before charging to the oven. Flash-dried coal may be transported directly to the ovens by the hot gases used for moisture removal. Wall temperatures should stay above 1100°C (2000°F) during loading operations and actual coking.

12.2 Coke Production - US EPA

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

Coal to Make Coke and Steel, Kentucky Geological Survey .

The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released. During this process, it softens, then liquefies, and re-solidifies into a hard porous material called "coke". This is not the cola soft drink.

Coal & steel | World Coal Association

Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.

History of Coke - Mining History Resources - Coal Culture .

Walston also had its own deep well for drenching the coke before it was taken out of the ovens. This combination of good coal and pure water make a high grade of coke, which competed successfully for a decade with the coke of the famous Connellsville region. By July, 1885, 500 men worked at Walston.

Museum | Penn State Fayette

Coal had been mined for many years before the idea of making coke in beehive ovens became popular. Coke is the bones of coal. In a general way, coke is as near a pure carbon as may be had; as near an uncrystalized diamond as can be made.

Coke in West Cumberland | Industrial History of Cumbria

The new coke ovens were, however, designed to use crushed coal of about a quarter of an inch down, and the economics of the process enabled it to absorb the cost of washing and crushing. Consequently a coal washery became a feature at all the collieries where the new ovens were installed.

Solvay Coke, Milwaukee, WI - SUBSTREET

Not that coke isn’t coal—not exactly. The process of making coke is straightforward. One builds an airtight oven, packs it with coal, seals the oven, then heats the coal until all the impurities burn out in the form of gas, leaving the only thing that would not convert into gas (without oxygen, of course)—the carbon in the coal.

Making steel without coal: Lets talk about coal

This has a much higher energy value than coal, and is better geared to producing high temperatures for smelting. Coke came into use in Great Britain in the 1700s, partly because of its superior crushing strength to that of coal. Blast furnaces for making iron and steel could be built taller and bigger, to improve economies of scale.

What You Should Know About Metallurgical Coal

Coke Making . Coke making is effectively the carbonization of coal at high temperatures. Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius (2,000 .

Steel Production - American Iron and Steel Institute

Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.

Corsa Coal Corp. - Coal in Steelmaking

The grade of coal and its coking ability are determined by the coal's rank—a measure of volatile matter and degree of metamorphism—as well as mineral impurities and the ability of the coal to melt, swell and resolidify when heated. Coke making is effectively the carbonization of coal at high temperatures.
