Abstract
A checkerwork for two upright regeneration chambers of a glass melting furnace defines a multiplicity of adjacently arranged vertical passages alternatingly providing upwardly directed fresh air flow and downwardly directed exhaust flow, the passages being connected by vertically spaced openings producing air turbulence, and the vertical distance between vertically adjacent openings becoming progressively smaller towards the uppermost checkerwork region.
