01/01/2013· Coal or coal briquettes enter the dome of the meltergasifier and is converted to char at °C. Oxygen is blown into the meltergasifier and generates a reduction gas upon gasification of the coal. This gas (mainly CO + H 2) is fed to the upper reactor(s), where the burden is reduced. The reduced iron ore or hot DRI is charged into the ...
WhatsAppعرض المزيدPulverized Coal Injection / Coal Dust Injection (PCI / CDI) Rate: Normally speaking, one tonne of Pulverized non cocking coal replaces one tonne of coke. Since coking coal / coke is scarce and costly, PCI is considered very relevant to minimize total coking coal consumption as well as cost of production. . It is expressed in Kgs of noncoking coal consumed per tonne of Hot Metal produced in ...

WhatsAppعرض المزيدPulverised coal injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for ironmaking – 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. This method has a number of advantages, including reducing ...
