Clean Air Journal How a Coke Plant Works by Baraa Ashour | Oct 4, 2018 How a Coke Plant Works by Baraa Ashour Oct 4, 2018 Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful byproducts that come from that.

A charge of coal is introduced through a hole in the top, leveled, and then heated, after the oven is sealed, by combustion of coal gas in heating flues at the sides. The gases, tars, and liquors are collected from the oven, if required, and separated in an adjacent byproducts plant.

In the steelmaking process, coke is used in the blast furnace as a (1) fuel to produce added heat; (2) chemicalreducing agent for the reduction of iron oxides; and (3) as a permeable support in the molten material in the furnace. Byproducts from coke ovens are used in the chemical industry (see Coal for chemicals and specialty products).

1. OBJECTIVE: The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant.

To combat global warming, industry needs to find ways to reduce its carbon footprint. One way this can be done is by reuse of industrial flue gases to produce valueadded chemicals. Prime example feedstocks for the chemical industry are the three flue gases produced during conventional steel production: blast furnace gas (BFG), basic oxygen furnace gas (BOFG), and coke oven gas (COG), due to ...

Manufacturing 1 ton of steel needs 50 kg of hydrogen. Replacing coal with hydrogen would raise the total price of a ton of steel by almost onethird. If largescale hydrogen generation reduces the price of H 2 to €/kg by 2030, the price difference between green hydrogen steel and conventional steel would be 10%.

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. Prior to the 1880's, steel was produced using charcoal.
