The invention relates to a recuperator (3) for a recuperative burner (1), said recuperator comprising a hot side and a cold side; a housing (31) which is closed in the circumferential direction and surrounds an exhaust gas channel (32) through which a flow can pass in the longitudinal direction; and a plurality of heat exchanger tubes located in the exhaust gas channel, wherein a first connection chamber (301) having a first supply connection (37) for combustion air and a second connection chamber (302) having a second supply connection (38) for a fuel gas are provided on the cold side of the exhaust gas channel (32), wherein the exhaust gas channel (32) is divided at least into a first segment (321) fluidically connected to the first connection chamber (301) and a second segment (322) fluidically connected to the second connection chamber (302), in each of which segments some of the heat exchanger tubes (33) are located and through which the exhaust gas can flow in parallel, the division of the exhaust gas channel being such that the ratio of the heat capacity flow of the cold side to the heat capacity flow of the hot side is between 0.9 and 1.1. The invention also relates to a recuperative burner (1).
A recuperator for a recuperative burner, having a hot side and a cold side, having a housing which is closed in the circumferential direction and which surrounds an exhaust gas duct through which an exhaust gas can flow in the longitudinal direction, and having a plurality of heat exchanger tubes arranged in the exhaust gas duct, wherein a first connection chamber with a first supply connection for combustion air and a second connection chamber with a second supply connection for a combustion gas are provided on the cold side of the exhaust gas duct, wherein the exhaust gas duct is subdivided at least into a first segment fluidically connected to the first connection chamber and a second segment fluidically connected to the second connection chamber, in each of which a part of the heat exchanger tubes is arranged and through which the exhaust gas can flow in parallel, such that a ratio of the heat capacity flow of the cold side to the heat capacity flow of the hot side is between 0.9 and 1.1.
