A ceramic recuperator (18) for a recuperator burner (1) is provided, in its heat exchanger region, with a plurality of radially inward- and outward-extending teeth. On the otherwise hollow-cylindrical recuperator (18), the teeth (19) are arranged in groups, e.g., in rings; the teeth of one ring are each offset from the teeth of an adjacent ring. Alternatively, it is possible to arrange the teeth on a single- or multi-start helical line. The recuperator can be produced economically by the slip-casting method.
