Abstract:

An exhaust gas burner assembly includes a body, an inlet opening, an outlet opening, a first chamber, a second chamber, and an intermediate opening. The exhaust gas burner assembly also includes a perforated pipe disposed between the first chamber and the second chamber, a fluid injector adapted to discharge a combustible mixture, and an igniter adapted to ignite the combustible mixture to generate combustion products. The perforated pipe allows at least a portion of the exhaust gas to flow therethrough from the first chamber to the second chamber such that the exhaust gas exiting the outlet opening has a higher temperature than the exhaust gas entering through the inlet opening.
