The iron and steel sector is one of the major CO 2 stationary emitters out of the power sector where CCS could be installed contributing significantly to the mitigation effort. The majority of CO 2 emissions arise from the coal consumption in the blast furnace, although there are other large sources of CO 2 in a steel plant: the internal power plant, the hot blast stove, the coke oven, etc ...
Thermal coal is also used in some of the processes for ironmaking especially in the production of direct reduced iron (DRI) and in the smelting reduction processes for the production of hot metal (HM). Thermal coal is a complex heterogeneous substance. Hence, it has no fixed chemical formula. Its characteristics and hence its CV vary widely.

Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. 3.19.1.1.2 Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.
These are: Plant material, wood. Peat. Brown coal (lignite) Black coal (sub-bituminous, bituminous and anthracite) …. Each successive stage has a lower water content and a higher energy content. This means that when the same quantity of each material is burned, a greater amount of heat is released for each successive stage.
The iron and steel industry – where we are Total world crude steel production in 2012: 1 542 Mt Energy costs represent around 20 to 25 % of the total input of steel producers and it becomes one of the most important topic of steel producers Coking coal accounts for more than 65% of primary source of energy 4 BF / BOF: 69.6% EAF: 29.3 %
Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
At present, the Division operates four open cast coal mines viz., Quarry A, C D & SEB and two coal Washeries to produce about 2.5 MTPA of coking coal at 18% ash for the steel plant. Both Washeries produce clean coal at 18% ash and three types of coal by-products i.e. middlings, tailings and rejects.
Coking Coal for steel production and alternatives. Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel, …
Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke.Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking.

Each type has different proportions of carbon and thus, have different uses. Peat - This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used. Lignite - This type of coal has 40% - 55% carbon content, which implies that moisture content is lesser ...
coal in the United States is between 100 to 300 million years old. It is the most abundant rank of coal found in the United States, accounting for about half of U.S. coal production. Bituminous coal is used to generate electricity and is an important fuel and raw material for the steel and iron industries.
The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled and screened into pieces ranging from one inch to four inches. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong.
The most plentiful form of coal in the United States, bituminous coal is used primarily to generate electricity and make coke for the steel industry. The fastest growing market for coal, though still a small one, is supplying heat for industrial processes.
What are the types of coal? There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.
Coal fired power plants are a type of power plant that make use of the combustion of coal in order to generate electricity.
