The main use of coke is to make iron. The burning of coal to coke produces carbon monoxide. A touch at the bottom of the furnace allows impurities to flow out of the furnace.
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 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 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.
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 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.
How does a blast furnace work?
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
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.
How is coke obtained from coal?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is “coked”, or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
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.
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.
What is charcoal vs coal?
Coal is a rock you dig out of the ground (that much I knew). Charcoal is a man-made product, and it’s made from wood. … This general process of partially combusting a fuel by heating it in the absence of oxygen is called charring, and it can be applied to coal as well. Confusingly, charred coal is called “coke”.
Do you need coke to make steel?
But steel production would not be possible without the use of coal and coke. What is coke? 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.
How does a coke oven battery work?
A coke battery is made up of multiple ovens. 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.
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.
