Why do we use coke instead of coal? 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.

These coals are referred to as metallurgical coal, met coal, or coking coal. These can be considered grade terms. Coke (not the soft drink) is a hard, porous, carbon-rich compound. Only coals with specific quality characteristics can be used to make coke. Metallurgical grade coals for steel production must be very low in ash (generally less ...

The key difference between coal and coke is that Coal is a naturally occurring fossil fuel. Coke, on the other hand, is derived from heating coal. In other words, Coal originates naturally from the fossilization of organic matter over millions of years. In contrast, Coke is derived from coal through a process called coking, involving high ...

Coke-making is the process of heating coal to produce coke, the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature.

It was built by the U.S. Coal and Coke Company, part of United States Steel, in 1917 and named for Thomas Lynch, the company's first president," the Kentucky Atlas and Gazetteer says. "The population peaked around 10,000 in the 1940s and was the largest coal camp in the world. The town was sold to the residents in the 1950s.

Metallurgical coal is a special type of coal used to make metallurgical coke. There are two types of metallurgical coal used to make coke: hard coking coal and semisoft coking coal. According to Grande Cache Coal, these types of coal are ideal for coke because they melt, swell and re-solidify when placed into a superheated furnace.

During the process of coking coal at coke plants, several pollutants are generated and released from the coke ovens to the atmosphere. The main harmful emissions are NOx, SO 2 gases, and particulate matter whose source is the flue gas from the combustion of cleaned coke oven gas in the battery. Among the modern emission …

Coke also has a higher amount of ash content than coal. Coke is rich in carbon, with a calorific value of about 6,000 BTU per pound. It gives off energy at temperatures exceeding 3,800 degrees Celsius when burning. Coal contains around 30–60% carbon but produces carbon dioxide and soot when it burns. Coal's calorific value is around 3,800 ...

Bio-Coke is a new densification product produced from biomass that aims to substitute coal coke usage. Bio-Coke is known to have a better density (1330–1450 kg/m 3) and mechanical strength at both room (44.50–167 MPa) and at high temperatures (700 °C) (1.49–9.41 MPa) which makes it suitable for use in many practical applications …

The requirements on coke quality for blast-furnace use are fairly stringent: CRI ≤ 30%; and CSR ≥ 60%. That entails the use of high-quality coking coal with specific petrographic characteristics, optimal clinkering properties, and optimal mineral composition. Because of these strict requirements, coke is very expensive.
