Abstract

A refractory tile (30) adapted for protecting boiler tubes (20) from the corrosive and erosive effects of a hot gas stream comprises an elongated ceramic body (38) covering only that side of a boiler tube (20) upon which the hot gas impinges. The tile (30) is hung on the tube (20) with a threaded stud anchored on the tube (20) and a nut threaded on the stud, urging the tile (30) against the tube (20).
