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. The coke, when exposed to oxygen, will immediately ignite and begin to burn.
What is the production process of coke?
Coke manufacturing includes preparing, charging, and heating the coal; removing and cooling the coke product; and cooling, cleaning, and recycling the oven gas. Coal is prepared for coking by pulverizing so that 80 to 90 percent passes through a 3.2 millimeter (1/8 inch) screen.
What does a coke oven produce?
The coke ovens use thermal energy (coke oven and blast furnace gas) to make coke. The amount of thermal energy depends on the nature of coking coal used, coke oven design, and operating practice.
What is coke oven in steel plant?
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.
How did old coke ovens work?
A worker known as a “scraper” leveled off the coal by reaching in through the door in the front of the oven. He did that so the coke would burn evenly. “The coal was loaded, or “charged”, into an oven that was between two hot ovens, so that the newly-charged oven could light itself by spontaneous combustion.
What is coke oven battery?
A battery consists of a group of ovens connected by common walls. ♦ Coke oven emissions are among the most toxic of all air. pollutants. Emissions from coke ovens include a mixture of polycyclic organic matter, benzene, and other chemicals that can cause cancer.

How does a coking plant work?
How does this work? The coal is heated to 1.250° C in the coke ovens. During the distillation process, a large amount of gas and smoke is generated, which –after purification– creates coke oven gas and other valuable by-products, such as tar, sulphur, ammonia, naphthalene and benzole.
What is BF BOF?
Blast furnace – basic oxygen furnace (BF-BOF) process and electric arc furnace (EAF) process are the two most common routes of steel production.
Why coke is not used as a fuel?
Answer: because fuel has different properties than coke as fuel can help a car move and coke can’t do do that as it does not have the chemicals to complete that task …
How old are the coke ovens in it?
| Dunlap coke ovens | |

Why is coke a cleaner fuel than coal?
Coke is a fuel with few impurities and a high carbon content, usually made from coal. -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.
When was the first coke-oven plant built?
Within three years of the official ground- breaking in March 2000 and the laying of the foundation stone in July 2000, the world’s most modern, environmentally- friendly and, in terms of its dimensions, unique coke-oven plant took shape on the basis of engineering performed by ThyssenKrupp Industrial Solutions.
How is Coke separated from the gas in an oven?
The gases, tars, and liquors are collected from the oven, if required, and separated in an adjacent by-products plant. When carbonization is complete, the heating is stopped, the doors removed, and the hot coke discharged from one end by pushing at the other.
How much Coke does the Schwelgern coke-oven plant produce?
