Abstract
A ceramic tube recuperator for recovering energy from hot flue gases, in which a multiplicity of heat exchange elements connected to a cold air inlet manifold and a hot air outlet chamber extend upwardly into a flow passage for hot flue gases. Each heat exchanger comprises an inner open ended tube extending into the cold air inlet manifold, and an outer ceramic tube having a closed upper end and an open lower end communicating with the hot air chamber. An essential feature of the invention is that the lower end of the ceramic tube is sealed solely as a result of resting on an annular seal, so that the ceramic tube may be removed and replaced simply by lifting and lowering through an access opening in the flue passage.
