Abstract
Regenerator packing members are constructed and arranged to form tapered passageways interconnecting regenerator flues to induce transverse flow of gas between flues for increased heat transfer. A preferred embodiment includes parallelepiped bricks arranged in an open basketweave pattern, with spaces between brick ends and side faces defining the tapered passageways.
