Pulverized Coal Injection
The injection of pulverized coal into a blast furnace has become the most important secondary fuel for iron making. The advantages of pulverized coal injection are obvious:
-
Replacement of 30 to 40 (up to 50) percent of the coke charge
-
Substitution of existing oil or natural gas injection
-
Reduction of fuel costs
-
Reduction of pollution of coke making
-
Lower capital costs by investing into coal injection system instead of coke batteries
-
Return On Investment between 6 months and 3 years
