In a process known as “coking,” coal was shoveled into beehive-shaped coke ovens insulated with a layer of dirt and then ignited. After laborers sealed the doors with brick and mud, the coal was left burning under low-oxygen conditions for two or three days and could reach temperatures of nearly 2000C (or 3600F).
How does a coke oven work?
Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. 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.
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.
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.
Does Coke burn hotter than coal?
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. … However, blacksmiths still rely on coke as an efficient source of fuel for the forge.
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.
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.
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 were coke ovens 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 can you use Coca Cola for?

Is Coke is a clean fuel?
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.
Is Coke a primary fuel?
coke,charcoal etc. Answer: Primary Fuels are the natural Fuel. … Fuel which we get from natural resources are primary fuels while artificial fuels are Secondary fuels .
Is Coke a smokeless fuel?
Smokeless fuels do not produce smoke when burned. Smokeless fuels are usually solid fossil fuels, such as: anthracite, coke, and charcoal. … Therefore when burned, coke and charcoal produce no smoke. Coke and charcoal have moderate to low carbon content and are cheaper than bituminous coals.
What is the hottest burning coal?
Why do we turn coal into coke?
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. … This process results in a hard porous material – coke.
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.
