Coke oven gas is formed by heating coal to 1100 °C without access of air. The classic composition of coke gas: hydrogen (H2 – 51%), methane (CH4 – 34%), carbon monoxide (CO – 10%), ethylene (C2H4 – 5%). The composition may also include benzene (C6H6), ammonia (NH3), hydrogen sulfide (H2S) and other components.
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 are coke oven products?
Coke oven emissions are the volatile products that are released from bituminous coal during its conversion to coke in high temperature ovens in the absence of air.
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.
What is coke for steel?
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.
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 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.
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 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.
What is difference between coke and coal?
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 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 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.
How is steel smelted?
Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. 2), a notable greenhouse gas. After successive interactions with carbon monoxide, all of the oxygen in the ore will be removed, leaving the raw metal element (e.g. Fe).
Which is better coal or coke?
Coke is a better fuel because coke produces more heat on burning as compared to coal. Coke has higher calorific value than coal. When equal masses of coke and coal are bunt, coke produces more heat. Also when coke is burnt, smoke is not obtained whereas coal produces smoke on coal.
How do you create steel?
To make steel, iron ore is heated and melted in furnaces where the impurities are removed and carbon added. Today, most steel is made using one of two processes: Blast Furnace. Electric Arc Furnace (EAF)
What is coke rate?
Coke rate is the parameter for the consumption of BF coke which is measured in kilograms of BF coke consumed per ton of hot metal produced. Blast furnace (BF) coke is a key material for BF ironmaking, acting as a major energy source (fuel), a reductant, a carburization agent and a permeable structural support.
