blast furnace pulverized coal production process
CFD studies of pulverized coal and blast furnace top gas (BFG) injection and found that coal burnout decreased with increasing BFG injection because the BFG consumed oxy-gen, reducing the amount of oxygen available to react
Pulverized coal injection method 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.
In the classic blast furnace process around 300 kilograms of coke and 200 kilograms of pulverized coal are needed to produce a ton of pig iron. The coal is injected as an additional reducing agent into the bottom of the blast
