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