Pulverized Coal Injection Industrial Efficiency Technology Measures

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.

Pulverized coal injection method Wikipedia

Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Rises in the cost of coke due to increased global demand and thus more competition for the resource have made this method attractive to the ironproducing industries and increased its value.

Index for IronBased Slagging for Pulverized Coal Firing in Oxidizing ...

A model for the prediction of ironbased slagging precursors from the combustion of ironcontaining coals is detailed. The model accounts for the form of iron (pyrite or siderite), the distribution of iron within the pulverized coal, temperature, and oxidizing or reducing conditions. The input required for the model is a CCSEM analysis of the pulverized coal. For oxidizing conditions, the ...

Steel Raw Materials: Weekly Market Tracker Metal Bulletin

Sep 21, 2022This is called pulverised coal injection (PCI) and the coal used is called PCI coal. One tonne of PCI coal replaces about of coking coal. Steam coal is used for PCI because it has a lower price than coking coal, but PCI coal needs to be less than 7% (on an airdried basis) and less than 10% total moisture and low in alkalis and phosphorous.

Injection of coal and waste plastics in blast furnaces USEA

as high as the pulverised coal normally injected, and their higher ratio of hydrogen to carbon means less CO2 is produced within the BF from the combustion and iron ore reduction processes; lower energy consumption. Hydrogen is a more favourable reducing agent than carbon. The regeneration of hydrogen is faster and less endothermic than carbon

Pulverised Coal Firing of Small Boiler Plant

Why pulverised coal firing? The firing of coal in pulverised form offers great advantages. Once it has been pulverised, it becomes a homogeneous, con trolled powder, which no longer has to be burnt in contact with cast iron grates. The burner resembles an oil burner, in asmuch as combustion takes place in suspension in a very

Metallurgical coal | BHP

Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth''s crust. Categories of met coal include hard coking coal, semihard cokingcoal, semisoft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
