Abstract
A method of injecting selected material along a preselected path into charged material. The charged material at least partially obstructs the preselected path. An injection device includes a central barrel through which a carrier stream of a transport gas is directed, and the selected material is introduced into the carrier stream to form a transport stream that exits the central barrel at an output end. The injection device also includes an outer barrel coaxial with the central barrel to define an annular space. An annular shroud stream of a shroud gas exits the annular space at a downstream end. The annular shroud is directed along the preselected path to provide an opening in the scrap steel pieces. Subsequently, the transport stream and the annular shroud stream are directed along the predetermined path to inject the selected material through the opening into the charged material.
