ABSTRACT:
Straight and arcuately curved superheater tube shields of refractory material comprising a pair of elongated half shields of identical interchangeable interfitting and interlocking size and shape, each half shield having a semicircular sidewall of corresponding straight or arcuate shape of predetermined radius of curvature extending between opposite ends and to inner diametrically opposite inner sides lying in a central plane and the plane of curvature. A number of mating camming portions with inclined camming surfaces are precisely spaced adjacent each of the inner sides so that one of the half shields may be turned end for end relative to and assembled to the other about a correspondingly shaped superheater tube by a relatively short axial movement and engagement of the inclined camming surfaces whereby the half shields are pulled together to close the joints therebetween and interlocked about the superheater tube. A refractory cement may be applied to attach the half shields to the tubes.
