The ceramic recuperator (30) for a recuperative burner (10) has a pipe section serving as a heat exchange surface with flowing fluids, and which has a number of folds (36). The folds extend in spiral fashion in relation to the longitudinal axis of the recuperator. The folds are constantly curved and constructed especially in wave form. The pipe section has an outer pipe (24) and an inner pipe (14) forming an outer (38) and an inner (32) chamber for passage of fluid. A gap (34,39) remains between the outer pipe and folds, or between the inner pipe and folds. An independent claim is included for a recuperative burner with a ceramic recuperator installed between the flame tube constituting the inner pipe and exhaust gas guide pipe constituting the outer pipe. |
