Abstract
A method for injecting a solid feed material through a solids injection lance includes creating flow conditions in an injection passageway of the lance so that at least a part of the feed material flowing along the passageway forms a buffer zone between a wall of a tube that defines the passageway and feed material flowing along a central section of the passageway.
