Limited availability of coking coal in India and world wide will encourage Steel production in the country through combination of DRI & BF e.g. DRI-BF-EAF route. We in SIMA are of the opinion that DRI industry is going to play an increasingly important role in augmenting steel production in India.
Pulverized Coal Injection (PCI) System This technology is for injecting pulverized coal directly through the blast furnace tuyeres as a partial substitute for the coke used in the blast furnace. - 1.55 147 (emission factor: steam coal) assuming 125kg coal injection - 91 A-9 Hot Stove Waste Heat Recovery This device recovers the sensible heat
Pulverised coal injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal.
Coal injection system. Reduced pollution Coal grinding and injection systems are non-polluting systems. Injecting pulverized coal into a blast furnace reduces the overall pollution made by coke production. Increased productivity Installation of a coal injection system can increase productivity through improved operation of the blast furnace.
coal, is a vital ingredient in the steel making process. Steel is a man-made alloy of iron and carbon – carbon is found in coal. >> Coal is abundant, affordable and geographically well-distributed. Major developed and developing economies are able to utilise large indigenous coal reserves, while coal is also available from a wide
Pulverised coal injection (PCI) is a well established technology. It is practised in most, if not all, countries with coke-based BFs, and new BFs are nearly always fitted with PCI capability. Waste plastics injection (WPI) is less Injection of coal and waste plastics in blast furnaces 5 commonly carried out, with only a few ironmaking plants in
Extensive met coal Large met coal reserves Scrap/some DRI Favour BF/BOF + EAF Low grade iron ore reserves No Scrap Favour BF/BOF SE Asia China Russia India In addition to China steel growth to 2014 will be driven by other countries, with a majority favouring the BF route relying on imported seaborne coking coal and domestic iron ore. Brazil
Chromite, coking coal, steel grade limestone, refractory raw material, Nickel, Ferrous Scrap etc. Due to shortage of domestic coking coal, both in terms of quantity and quality, pig iron producers/ BF operators in India have to significantly depend on import of coking coal. 1.10.

China, Russia, Australia and India, coal is actively mined in more than 70 countries.9 • China is by far the biggest producer of coking coal in the world. ... a technology called Pulverised Coal Injection (PCI).10 One tonne of PCI coal .
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 ...
Standard characteristics of coke quality and test methods seem to be insufficient to simulate changing conditions in a modern BF, described in the next section (low coke rate, high pulverised coal injection rate, use of other injectants). They provide limited assessment .
Additionally, mills are increasingly investing in upgrading their furnaces to allow the use of pulverised coal injection (PCI), Roy added. Moreover, Indian mills are diversifying their coal sourcing, as reflected in the increasing share of coking coal sourced from across the Atlantic, and a corresponding lower share from Australia, he added.
In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column.
Coal mining in India began in 1774 when John Sumner and Suetonius Grant Heatly of the East India Company commenced commercial exploitation in the Raniganj Coalfield along the Western bank of Damodar river. Growth remained slow for nearly a century due to low demand.

Impact of PCI Coal Quality on BF Operations Impact of PCI Coal Quality on Blast Furnace Operations P Bennett*, T Fukushima** *CoalTech Pty Ltd, **F-TeCon Pty Ltd Contact: [email protected] ABSTRACT Pulverized coal injection has assisted the steel industry to lower operating costs, extend coke oven life and lower greenhouse emissions.
• The global met coal world has changed due to higher demand for BF based steel and hence metallurgical coke • Increasing demand and challenges from the BF have raised the bar for coke quality, requiring increased levels of hard coking coal • The current market tightness is anticipated to last for some time due to
