摘要

The economic benefits derived from supplemental fuel injection are of two types: 1) the reduction in costs of hot metal production arising primarily from decreased coke consumption, and 2) the value of the increased production of hot metal--and steel--that can be sold. All blast furnaces in North America inject supplemental fuel. Approximately two-thirds currently inject or coinject natural gas in the range from 30 to 200 pounds per ton of hot metal (lb/THM) or from 1,800 to 4,500 standard cubic feet per ton of hot metal (scf/THM). The total amount of natural gas consumed in North American blast furnaces is now about 100 billion cubic feet per year (bcfy).
