ABSTRACT:
A furnace lining is formed by a plurality of lining bricks. The bricks have surfaces defining an internal surface of the lining that is to face the interior of the furnace and to receive therefrom radiant heat. At least one depression is formed in the lining and opens onto the surface through an opening. The depression has internal wall surfaces that are geometrically configured to cause radiant heat from the furnace interior that impinges on a first internal wall surface to be reflected thereby and to impinge therefrom onto a second internal wall surface. Thus, the heat will be absorbed by the bricks of the lining, and such heat will be emitted thereby from the inner surface thereof.
