Abstract
A method (200) for operating an exhaust gas burner (120) in an exhaust section (102) of an internal combustion engine (110), comprising introducing a purging fluid comprising at least air (20) into the exhaust gas burner (120) during a purging operating phase (205), which lies outside the time of a normal operating phase (201) of the exhaust gas burner (120), and discharging a discharge mixture formed using the purging fluid from the exhaust gas burner (120), wherein the exhaust gas burner (120) is operated for the purpose of heating a component (130, 150) of the exhaust section (102) to its operating temperature during the normal operating phase (201). A processor unit (140) and a computer program for carrying out such a method (200) are furthermore proposed.
