Abstract
In the manufacture of a heat recuperator, a ribbed layered cross-flow ceramic core is inserted into a metal housing. The core has divider ribs in the air-flow layers to provide triple pass air flow through the core. There are triple pass gaskets on the air-in and air-out faces of the core, between said faces and cast ceramic landed surfaces of the housing.
