Hollow block for the chamber edge grid of a glass melting furnace

摘要

The angularly symmetric hollow block (1) of refractory material, with a polygonal prismatic outer contour and an interior channel (4) bounded by broader (2) and narrower side walls (3) is characterized by the following fact: the narrower side walls are provided with cutouts (5, 6), while the broader side walls are free from such cutouts. The cutouts are open to one of the block faces (7, 8). An Independent claim is also included for the use of the hollow blocks for chamber edge grids of glass melting furnaces which is characterized in that the blocks are rotationally offset relative to one another. The top or bottom cutout (5, 6) of a block is always faced by a wall region without a cutout belonging to the adjacent block.
