Four design variants of a full-flow burner for the thermal regeneration of a particle filter in an exhaust gas aftertreatment system of an internal combustion engine, especially a diesel engine, which is arranged fully in the tailpipe, especially in an expanded, straight coaxial tailpipe section, are suggested according to the present invention. As a result, the flow can enter a particle filter axially, which means simplified design and good temperature distribution. The full-flow burners are preheated by the heat of the exhaust gas of the engine during the start phase. The exhaust gas of the engine cools the burner surface during the phase of burner operation, so that thermal overload is avoided.
