coal processing in steel plants:

Coal steel World Coal Association

Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. The BF-BOF route is used for 71% of steel produced, whilst the EAF route accounts for 29% of steel produced. The key difference between these routes is the material used to produce the steel and the plant configuration.

Metallurgical coal - Wikipedia

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. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply. Metallurgical coal comes mainly from Canada, the United States, and Australia. In the United States, th

Steel Production - American Iron and Steel Institute

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 metallurgical plants use coal, coke, oil, gas, and electricity (generally coal based) to meet their needs for energy. The proportion of form of energy use depends on its availability in the particular area. Figure 4.2.4 shows examples from plants producing steel [11] and aluminum [12].It is observed that the major energy source is coal in both cases which is used to meet thermal and ...

COAL EXTRACTION AND PROCESSING - WordPress

the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.

Decarbonization in steel McKinsey

While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coal-dependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon ...

How a Coke Plant Works - GASP

Oct 04, 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 by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first. Coke is used as fuel in a blast furnace.

Steelmaking CO2 carbon dioxide emissions by process step

DRI-based EAF plants emit approx. 2-3 tonnes CO2 per tonne of steel if they are coal based, or 0.7-1.2 tonnes/tonne if they are gas-based. Direct emissions from scrap based EAF plants are mostly indirect –the CO2 emissions are not produced by the steel plant, but by the electricity generators that supply electricity to the furnaces.
