ABSTRACT:
An interlocking checker brick used to form a checkerwork for use in recovering heat in thermal regenerators and recuperators. The checker brick is made of a refractory material and is of a generally trapezoidal shape with each side wall having at least a section forming an acute angle with respect to the base. The preferred brick has spaced side walls each of which includes top and bottom sections adjacent to and perpendicular to top and bottom surfaces respectively. Each side wall also includes a central section flaring outwardly and downwardly from its top to its bottom section. Checkerworks utilizing these bricks increase turbulence while reducing laminar flow during alternating cycles of flowing gases and air. A method for making the preferred brick includes positioning a bottom section in complemental relationship with a mold cavity lower entrance, placing a quantity of brick mold material in the cavity, relatively moving an upper section to an upper entrance to the mold cavity, and thereafter, compressing the material to a predetermined uniform material density.
