249,919. Teisen, T. Dec. 31, 1924. Regenerators.-A tubular brick t of substantially uniform wall thickness for heat transfer purposes is provided at each end with coaxial hexagonal flanges of unequal lengths, one flange b having a spigot and the other a a corresponding socket, such bricks together with end tubes and spacing pieces d being built up to form recuperators in which one gas passes through the tubes and the other around them, or regenerators in which the gases pass only around the tubes. The intermediate part between the flanges may also be of hexagonal shape and may be provided on two opposite pairs of side walls with external teeth c to break up the fluid stream. For each horizontal layer the direction of the bricks t is reversed so that they are bonded due to the unequal lengths of the flanges. The distance-pieces d each have the shape of a quadrant of the hexagonal flange, and are provided with grooves filled with cement to prevent leakage. End tubes of two different lengths are provided so that the end walls come flush. In Fig. 10, i, j are the inlet and outlet passages for air passing upwardly in a zig-zag path around the bricks, which are set so that for every vertical channel there are two inclined channels causing a further mixing action. Waste gases pass through the tubes, being baffled by division slabs o, and teeth similar to the teeth c may also be provided within the tubes. The area of passage for the air may be increased as the air expands by making the recuperator broader at the upper part.
