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.
How did coke ovens work?
In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke” remains. The coke, when exposed to oxygen, will immediately ignite and begin to burn.
What is an old coke oven?
The coke ovens were used to convert the coal mined in the local area into industrial coke, a relatively clean-burning fuel used in the smelting of iron ore. … In a process known as “coking,” coal was shoveled into an insolated beehive-shaped and ignited.
What does a coke plant produce?
The carbonization by-products are usually refined within the coke plant to commodity chemicals such as elemental sulfur, ammonium sulfate, benzene, toluene, xylene and naphthalene. Subsequent processing of these chemicals produces a large number of other chemicals and materials.
How does a beehive coke oven work?
Each oven was heated to a temperature of over 2000 degrees Fahrenheit. When the coal is baked inside the ovens, the moisture and volatile chemicals are driven off, leaving a porous material that is almost pure carbon.
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.
Why Coke is not used as a fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
Where is Coke used?
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 is Coke vs coal?
By distilling bituminous coal in retorts to obtain gas for illumination, or by burning it in kilns or pits, the residue left behind is called coke, which is simply coal charcoal, and is nearly pure carbon.
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.
What is coke oven in steel plant?
When coking coal is heated in absence of air, a series of physical and chemical changes take place with the evolution of gases and vapours, and the solid residue left behind is called coke. Conventional cokemaking is done in a coke oven battery of ovens sandwiched between heating walls.
Is Coke a carbon?
Coke is an almost pure form of carbon. The calorific value (heat energy produced when a fuel is burnt) of coke is about 56,000 kilojoules/kilogram.
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.
