Preferably the ceramic tubes are made up of inner and outer coaxial ceramic tubes each connecting to a separate top manifold.
Claims5
A recuperator having a chamber traversed by combustion gases, the improvement comprising a plurality of outer ceramic outer tubes in contact with said combustion gases, said tubes being closed at their bottom ends and open to a first manifold at their top, a like plurality of inner ceramic tubes extending coaxially within the outer tubes and forming an annulus therebetween and open at the bottom ends spaced from the end of the outer tube, the upper end of said inner tubes open to a second manifold, whereby gases to be heated pass through said second manifold, through the inner tube, through the annulus between the inner and outer tubes and out through the first manifold, suspension means in each manifold removably and sealingly receiving and supporting said inner and outer tubes respectively in each said manifold.
