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.
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.
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.
What is a coke oven battery?
Normally, a coke battery comprises a large number of ovens, typically a set from 60 to 90 per battery, grouped in ‘sections’ of 15 to 20. This Coke Plant, with a total tonnage per year of 1.6 Mt/y, is composed by four different batteries, 80 ovens each, totalizing 320 ovens. …
What is 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.
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.
Does burning coke produce carbon dioxide?
At temperatures of 1000°C and above, coke carbon reacts with carbon dioxide to produce carbon monoxide, gasifying the coke in the process.
How do you make a coke oven?
It is used to produce Coal Coke (used as an alternative to Charcoal in the Blast Furnace) and Creosote Oil. The structure is made by placing Coke Oven Bricks in a 3x3x3 cube without the middle block. 104 Brick and 130 Sand are required to create one Coke Oven, a total of 26 Coke Oven Bricks.
Why Coke is used in blast furnace not coal?
Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel.
What is Coke in 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.
Is Coke 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.
Which is better coke or coal?
Coke is a better fuel than coal because; -Coke produces more heat on burning than coal. -Coke has a higher calorific value than coal. When equal masses of coke and coal are burnt, coke produces more heat.
