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 comprises a rectangular top, a rectangular base, two side walls and two end walls. The end walls each have a generally trapezoidal shape and therefore each side wall has 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 are arranged to improve the amount of exposed brick surface that acts as a thermal surface and to increase turbulence while reducing laminar flow during alternating cycles of flowing gases and air. A method and apparatus for making the preferred brick is also disclosed.
