Zusammenfassung:	A burner for an exhaust gas treatment system treats an exhaust flow from an engine and includes an inner housing defining a primary combustion zone and a secondary combustion zone. The inner housing includes a plurality of apertures upstream of the secondary combustion zone for receipt of a first portion of the exhaust flow. An outer housing surrounds the inner housing to define a bypass flow path between the inner and outer housings to bypass a second portion of the exhaust flow around the inner housing outside of the primary and secondary combustion zones. The outer housing includes an exhaust inlet coaxially aligned with an exhaust outlet along a central longitudinal axis. A mixing zone is provided downstream of the second combustion chamber in receipt of the first and second portions of the exhaust flow.
