Abstract

The present invention relates to specially shaped structural components for use in the construction of furnaces, foundries, and similar applications. In particular, the present invention relates to an improved flue wall in a high temperature furnace. The improved flue wall is constructed of specially shaped bricks to improve the tensile strength of the wall, increase the shear transfer capacity of the wall, and thus improve the flue wall life. The flue wall is constructed of specially designed refractory bricks joined together by air and/or heat-set mortar and arranged in courses, and comprises two parallel face walls parallel to the chambers wherein the carbon blocks are positioned and enclosing a flue chamber, two side walls generally perpendicular to the face walls enclosing the lower portion of the flue chamber, and baffle bricks and tie bricks arranged in a number of noncontinuous columns throughout the flue wall. In general the flue wall comprises H-shaped bricks used in the construction of the face walls, K-shaped bricks or C-shaped bricks used in the construction of the side walls of the flue wall to integrate the side wall with the first column of tie bricks, and I-shaped bricks used in the first column of baffle bricks and second column of tie bricks.
