Integrated coal-fueled steel mills accounted for ∼60% of the 1.4 Gt of global steel produced in 2008, consuming 15–18 GJ per t-steel produced and emitting a global average of ∼1.4 t-CO 2 per t-steel produced. In the first stage of the steelmaking process, high-grade coal (anthracite) is used to fuel a blast furnace in which iron is extracted by reduction from the ore hematite (Fe 2 O 3
Oct 21, 2018 Pulverized coal injection (PCI) is a well-established technology for hot metal (HM) production in a blast furnace (BF). It is practiced in most of the BFs and all the new BFs are normally built with PCI capability. The composition and properties of the coal used for injection can influence the operation, stability and productivity of the BF
China puts growth ahead of climate with surge in coal-powered steel mills. found that 18 steelmaking blast furnaces and 43 coal-fired power plants were announced in the first half of this year
dioxide emission is for one blast furnace, producing 4000 tons of hot metal per day, in one steel mill; far greater reductions could be achieved by use of anthracite in more furnaces and mills. In electric arc furnace applications, anthracite also enjoys an advantage relative to metallurgical coke, but the advantage is not so great.
Coke is burned as a fuel to heat the blast furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron. This is the basic chemical reaction in the blast furnace; it has the equation: Fe2O3 + 3CO = 3CO2 + 2Fe.
