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.
What are the two uses of coke?
Uses of Coke:
- The most common use of coke is as a fuel for stoves, furnaces and blacksmithing. It is sometimes preferred over coal because burning coke produces very little smoke.
- It is also used to produce iron in a blast furnace.
- Coke is used to manufacture steel and many other materials.
What are the uses of coke Class 8?
The uses of coke are as follows: It was used for domestic heating in the past. It is used for the extraction of metals. It is used in the manufacture of steel.
The characteristics of coke are as follows:
- It is a tough, porous and black substance.
- It is an almost pure form of carbon.
- It gives little or no smoke.
What are characteristics of coke?

- It burns without producing any smoke.
What is a coke oven used for?
Generally, the coke ovens found in the Cumberland region were used to convert the bituminous coal mined in the local mountains into industrial coke, a relatively clean-burning fuel used in the smelting of iron ore.
What is the meaning of coke?
distilled to dryness
What is the difference between coal and coke?
What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
Where is Coke used?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.
Which is the best type of coal?
What are the types of coal?
- Anthracite: The highest rank of coal. …
- Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. …
- Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite.
Which fuel is known as black gold?
What is hard coke?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. … The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product.
What is foundry coke?
Foundry coke is a high-quality grade of coke, also known as hard coal. … It is a large, strong coke used as a supporting matrix and energy carrier during foundry cupolas to produce cast and ductile iron products.
What is the role of coke in metallurgical process?
Metallurgical coke, along with iron ore and limestone, is layered into a blast furnace to convert the iron ore to metallic iron. Coke, which is mostly carbon, reacts with the blast air to produce carbon monoxide, which, in turn, reacts with the iron oxide to produce carbon dioxide and metallic iron.
What is the chemical formula of Coke?

What is coke oven gas?
Coke oven gas (COG), sometimes simply called “coke gas,” is a by-product of the coke-making process, where volatile coal matter is generated as COG, leaving carbon intensive coke behind.
Is Coke a fossil fuel?
Coal gas, coke and producer gas are the byproducts of coal and are not fossil fuels, except natural gas which is a fossil fuel.
