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 have a trapezoidal shape and therefore each side wall forms an acute angle with respect to the base. This provides a brick that tapers in thickness from the base to the top and is trapezoidal in cross 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.
