Lowercost PCI coal is injected into blast furnaces to reduce coking coal consumption. Essentially highquality thermal coal, PCI coal can be sold into either the metallurgical or thermal coal markets. Wood Mackenzie sees PCI coal coming under particularly high pressure under a 2˚C scenario with demand falling 50%.

Therefore, this work assesses the implications of different carbon allocation principles for the generation of lowcarbon products. The work evaluates the potential for reducing CO 2 emissions and the emissions intensities of the products, in a European setting, by implementing CCS and/or biosubstitution of pulverized coal injection (BioPCI) at an integrated steel mill that produces a ...

Fig 1 Typical flow sheet of pulverized coal injection in blast furnace. The process of coal injection. The PCI process is based on the simple concept of carrying the finely ground (pulverized) dried coal by a conveying gas (normally nitrogen) to the BF where it is distributed to different tuyeres and injected through a lance in the blow pipe.

Milling. The Hardgrove Grindability Index (HGI) is included in most thermal/PCI coal specifications as the indicator of mill performance. While HGI is adequate to characterise the grinding of most coals, some Australian coals can be disadvantaged as the HGI will indicate higher power requirements, lower throughputs and /or a coarser size ...

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. The PCI method is based on the simple ...
