Method and apparatus for electric steelmaking

摘要

A burner/injector (200) and method for providing a localized impingement flame or multiple flames for scrap heating and melting through use of a fluid fuel and at least one oxygen rich oxidizing gas. The burner/injector (200) includes a liquid-cooled combustor for generating an impinging flame directed toward a scrap pile and a structure for injecting a controllable amount of solid carbonaceous fuel (204) and a controllable flow of high velocity oxidizing gas (232) into space that has been previously occupied by the impinging flame.
