Abstract
This invention relates to an electric-arc fired blast furnace system for the reduction of iron-bearing material utilizing electric-arc heated air containing a reducing gas or carbon-containing fuel allowing for a decrease in the amount of coke normally used in the reduction process. The excess reducing gases exiting the furnace are utilized as a source of power via a system consisting of turbines, compressors and a heat exchanger to drive the electrical generators which are used to provide electricity to the arc heaters. This arrangement forms an essentially closed loop furnace system for metal reduction. Injection of finely-divided coal into the arc-heated air to provide reductants is also employed.
