Understanding Pulverized Coal Injection in Blast Furnace ...

21/10/2018  The injection system pneumatically transports and meters the pulverized coal from the storage bin through the injectant vessel, where it is pressurized up to or above the BF pressure, to the tuyere injection lances. The lances inject the coal in equal amounts through the tuyeres, which are arranged symmetrically around the circumference of the BF.

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 iron-producing industries and increased its value.
