  • Heat recuperative apparatus incorporating a cellular ceramic core
    Patent number: 4083400
    Abstract: High cell density (125 Cells/inch) cross-flow ceramic recuperators having high efficiencies are utilized for industrial waste heat recovery in an apparatus in which a ceramic recuperator core is surrounded by a metallic housing adapted for coupling to the metallic fittings of existing furnaces, ovens and preheaters. Insulating and sealing layers between the core and housing minimize heat loss through the housing and prevent leakage of the heat transfer fluids past the core.
