<p>A ceramic to metal joint particularly advantageous in a recuperator tube assembly, includes a ceramic tube and a spaced, circumferentially disposed metal sleeve. A bonding material is cast between the ceramic and metal members. A seal member has sufficient ductility within a predetermined thermal operating range to plastically deform and yet maintain an effective fluid seal between the ceramic and metal members. The present invention is particularly useful in the construction of a modular heat exchanger unit. Both individual tube assemblies and module units can be individually removed for cleaning, inspection, or replacement.</p> |
