ABSTRACT:
A composite sparger for use in elevated temperature and corrosive environments. The composite sparger is formed from a thermally conductive non-combustible metal substrate. The surfaces of the conductive non-combustible metal exposed to the reactor environment are protected with a corrosion resistant layer. The corrosion resistant layer protects the substrate material from the corrosive environment of the reactor vessel and the substrate material conducts heat away from the corrosion resistant layer to prevent combustion of the corrosion resistant layer. The substrate material and corrosion resistant material may be selected so as to provide for sufficient thermal conduction to prevent combustion of the corrosion resistant material.
