The use of HBI the Blast Furnace (BF)3

Benefits from using Hot Briquetted Iron (HBI):

Hot Briquetted Iron (HBI) is a manufactured product with guaranteed specifications.

Increased Productivity
Each 10% increase in burden metallization will increase iron production by about 8%

Decreased Coke Rate
Each 10% increase in burden metallization will decrease the coke rate by about 7% (100 kg HBI/mTHM = – 14% CO2/mTHM = – 43 kg coke/mTHM)

Decreased CO2 Emissions
(200kg HBI/mMTH = – 14% CO2/mTHM)

Compatible with injected fuels and oxygen

Other Features of Hot Briquetted Iron (HBI):

  • Compatible with iron ore handling equipment
  • Can be stored outside
  • Feeds easily from bins
  • Allows for flexible operation of multiple blast furnaces

Definition OF Hot Briquetted Iron (HBI)

A compacted form of Direct Reduced Iron (DRI) produced from iron ore fines, pellets, or lumps that are densified following reduction at a temperature greater than 650°C to have a density greater than 5000 kglm3, which makes it more resistant to reoxidation and fines generation.
