Heating device

A heating apparatus for an exhaust train, said heating apparatus comprising a flow-conducting device for guiding an exhaust gas flow along a flow path;

• a burner that is arranged outside the flow-conducting device and that is configured to generate heating gases during the combustion of a fuel;
• and a supply device that is configured to supply the heating gases generated by the burner to the exhaust gas flow, which is guided through the flow-conducting device, via a heating gas inlet that is formed in a wall of the flow-conducting device,
• wherein the supply device has a channel that is fastened to an outer side of the flow-conducting device in a manner covering the heating gas inlet and open towards it, wherein the channel extends along a peripheral direction running around the flow path and in so doing engages around the flow-conducting device while forming an interruption.
