ABSTRACT:
A recuperator having refractory walls has ceramic recuperator tubes which are located at each of their ends in tapering bores in the recuperator walls. The ends of the tubes are sealed in the bores in the walls by a number of precompressed fibrous refractory rings of different diameter which are in turn held in place and prevented from expanding by refractory locking rings that engage the sidewalls of the bores through a bayonet fitting. Ceramic inserts may be provided in the recuperator walls to form the bores. Buffer rings are provided between the locking rings and the tube ends, and a thrust washer is provided between the fibrous rings and the locking rings.
