Abstract
A refractory tile for a suspended wall of a glass furnace includes upper and lower horizontal faces having respective raised and depressed tongue and groove portions. The tile is adapted to be laid in overlapping or bonded courses such that the tongue and groove portions of a tile overlap and matingly engage the tongue and groove portions of two tiles in a subjacent course of tiles. Each tile also includes vertical side edges having mating ridges and grooves. Each of the tiles further includes a neck portion outwardly extending from a cold face edge thereof. The neck portion defines open spaces between adjacent tiles for insertion of insulation batts therein. The horizontal faces of the tiles also have slots formed therein for engagement with one of the hanger members. The slots have one of a transverse T-portion or a recessed portion formed therein and spaced inwardly from the cold face of the tile which are adapted to engage the hangers.
