Pitha, J R

The invention contemplates a fireplace comprising a stacked plurality of courses of modular prismatic blocks laid upon a base to define a firebox region of opposed side walls and a rear wall contiguous thereto. In one embodiment the blocks are characterized by at least one horizontal surface having external horizontal channel formations and by limited vertically extending end passages such that one or more vertically serpentine continuous air-flow ducts are established through successive horizontal channels in the stacked plurality of courses of the walls. Above the firebox region, and surrounding an associated chimney region, the wall-block courses continue, providing extension of the air-flow duct system into additional heat-exchanging relation with the chimney. The chimney-flue system also relies on modular blocks with vertical flue passages which register from one to the next course, the arrangement being such as to provide relatively large flue-surface area for extraction of flue-gas heat and to cause plural cycles of horizontal undulation of the vertical flow of exhausted flue gases, in their upward passage through the chimney.
