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.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.

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. 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.

Coal mill is a machine that crushes and grinds the coal briquette into pulverized coal. It is important auxiliary equipment of pulverized coal furnace. During the coal grinding process, the coal is crushed and its superficial area increases continually. To add new superficial area, the bond between solid molecules must be overcome, so the ...
In a wide variety of industries, e.g. in the cement and steel industry, an explosive dust atmosphere is created during the grinding of coal and similar products. This can lead to explosions and therefore requires the consideration of constructional explosion protection measures in the form of pressure relief devices.

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. By 1920, nearly 90% of US steel was produced using coke.
Pulverized Coal Injection (PCI) is a process that involves blowing large volumes of fine coal granules into the BF. This provides a supplemental carbon source to speed up the production of metallic iron, reducing the need for coke production. As a result energy use and emissions can be reduced. However, as coke provides physical support and gas permeability in the BF, its …
