ABSTRACT:
Ceramic honeycomb type recuperative heat exchangers having a large number of parallel channels formed of partition walls are disclosed, in which fluids to be heat-exchanged are passed through respective channels that are produced by extruding a ceramic raw batch material into a honeycomb structural body, drying the shaped honeycomb structural body, prior to or after firing step cutting off partition walls in the given rows of the honeycomb structural body in the axial direction of the channels to a given depth from the end surface of the honeycomb structural body and sealing only the end surfaces of said rows.
