Recuperative burner

A recuperative burner comprising:

• a burner base;
• a combustion chamber tube, in which at least one burner nozzle is positioned, at which at least one fuel gas line opens;
• an exhaust gas recirculation device with a jet pump which is operated by combustion air and comprises a jet nozzle, a cross section of which decreases in a flow direction, and comprises a jet pump annular gap for an intake of exhaust gases from outside a combustion chamber tube via an annular driving jet, the exhaust gas recirculation device being configured upstream of a mixing plane of the fuel gases flowing into the combustion chamber tube, between the burner base and the combustion chamber tube;
• at least one endless exhaust gas intake opening and/or a peripheral, self-contained arrangement of a plurality of exhaust gas intake openings, from which at least one flow path leads into an interior of the combustion chamber tube;
• and
• a recuperator arranged upstream of the combustion chamber tube, with a heat transfer body which has at least two separate throughflow channels provided to conduct counterflowing fluids,
• wherein at least two fluids enter/exit via inlet and outlet openings of the throughflow channels in the heat transfer body and, of the fluids, one is formed by combustion air to be preheated and the other is formed by the exhaust gas of the recuperative burner, and
• wherein the jet nozzle is formed at a combustion air outlet opening of the recuperator.
