ABSTRACT:
A lance for submerged injection of a feed composition, such as a waste, into a molten metal bath includes a perforate refractory tube which extends substantially coaxially about an injection tube. The perforate refractory tube shields the injection tube from the molten metal bath during partial submersion of the lance into the molten metal bath. A perforate support liner extends between the injection tube and the perforate refractory tube and supports the perforate refractory tube. The perforate support liner and the injection tube define an annulus. The method includes conducting a coolant from a coolant source through the annulus to perforations defined by the perforate support liner and the perforate refractory tube, whereby coolant can be directed through the perforations and into the molten metal bath to cause a protective coating of metal to form on the lance. The lance is thereby protected, preserving its structural and chemical integrity during submerged injection of the feed composition through the injection tube into the molten metal bath.
