Abstract
In a refractory brick assembly for a heat regenerator, a plurality of brick units are assembled so as to form many long vertical gas flow passages. Each outer wall of the brick units has four corner portions each of which has a plurality of convex and concave strips. That can engage with each other so as to hold the brick units due to the friction between them. A high projection is formed on at least one of the inner and outer walls for producing a turbulent flow.

A refractory brick assembly for a heat regenerator comprising a plurality of brick units assembled in both horizontal and vertical directions for forming a plurality of long vertical flow passages, each of the brick units having an inner wall, an outer wall and two opposite open ends, the inner wall defining a part of the vertical flow passages and having a center line between the open ends, the outer wall defining a part of the vertical flow passages, the outer wall having four corner portions which are arranged in contact with each other when they are assembled, each corner portion having concave and convex means in such a manner that the concave means can engage with the convex means when the adjacent corner portions engage with each other so that the brick units can be held in position, some selected brick units among the brick units being separate from vertically adjacent brick units so as to form cross-flow passages between them so that the vertical flow passages are connected to each other through the cross-flow passages.
A refractory brick assembly for a heat regenerator comprising a plurality of brick units assembled in both horizontal and vertical directions for forming a plurality of vertical flow passages, each of the brick units having an inner wall, an outer wall and two opposite open ends, the inner and outer walls having concave and convex strips, at least one projection formed on at least one of the inner and outer walls for producing a turbulent gas flow, the height of the projection being larger than that of the strips whereby a plurality of projections are placed in the shape of a flange in the vertical flow passages when the brick units are assembled.
