The various stages of the steel plant is described below. COKE MAKING COAL CARBONISATION : Coking coals are the coals which when heated in the absence of air, first melt, go in the plastic state, swell and resolidify to produce a solid coherent mass called coke. When coking coal is heated in absence of air, a series of physical and chemical ...

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.

Coke was first produced commercially in England in the early eighteenth century. By the early to mid1800s, coke was being widely produced in Europe and the United States of America as the major fuel for blast furnaces. Coal carbonization is a process that yields metallurgical coke for use in ironmaking blast furnaces and other metalsmelting ...

Coke is a very strong macroporous carbonaceous material produced by the carbonization of a specific coal grade or of different coal blends at temperatures ⩾1400 K. Approximately 90% of coke produced from blends of coking coals is used to maintain the iron production process in a blast furnace (BF) [9].

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).

Coke oven gas (COG) is highly rated as a valuable byproduct of coal carbonization to produce coke in the steel industry. Typically, a single ton of coke generates approximately 360 m 3 COG. China annually produces 70 billion N m 3 COG; however, only 20% of the gas produced is utilized as fuel. Disposing COG without an effective recovery and ...

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.

Coal traditionally has been a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.
