SWIRL-STABILIZED BURNER FOR THERMAL MANAGEMENT OF EXHAUST SYSTEM AND ASSOCIATED METHOD

摘要

An apparatus comprises a reciprocating or Wankel engine, an exhaust gas passageway fluidly coupled to the engine, and a fuel-fired burner. The burner is positioned in the exhaust gas passageway and comprises a swirler configured to swirl exhaust gas of the engine so as to stabilize in the exhaust gas passageway a flame generated by the burner without use of supplemental combustion air when the engine is operating above idle. An associated method is disclosed.
