Abstract
A superheater tube shield of refractory material comprises a pair of elongated half shields of identical interchangeable interlocking size and shape, each half shield having a semi-circular sidewall portion extending between and to diametrically opposite tongue and groove side wall portions which are assembled together about the tubes by axially inserting elongaged tongues into the elongated grooves. Refractory cement may be applied to attach the half sheilds to the tubes.
