REGENERATOR PACKING Russian patent published in 2014 - IPC C21B9/06 

FIELD: metallurgy.

SUBSTANCE: regenerator packing is made of refractory blocks, at the laying of which vertical channels and additional vertical passes are formed between the refractory blocks. Each of the refractory blocks includes vertical prismatic elements in the form of plates, which are parallel to each other and installed with equal gaps; the above plates are connected to each other by means of cylindrical connection straps. Some part of plates of the block is elongated and arranged in groups between shortened plates with length equal to thickness of the block. Elongated plates are projected on the side of one of lateral edges formed with end faces of plates. On outer surfaces of extreme plates there are vertical slots, the width of which is equal to width of the group of elongated plates considering thermal expansion. Size of projections exceeds depth of slots by the value of width of a gap between plates considering thermal expansion. Refractory blocks are laid in pairs at the distance from each other, which is equal to width of the gap between plates of the block. Projections and slots of paired blocks are arranged along their perimeter and combined with slots and projections of adjacent paired blocks that alternate with them as to the height and laid with an offset of 90°. Blocks are installed in a vertical plane without any offset; vertical channels and passes are connected to each other and have the same width.

EFFECT: high specific surface of the packing and its stability at operation.
