Definitions

  • the invention is also usefully executed such that the burner has a burnout zone and that the secondary air which is supplied to the burnout zone has higher angular momentum than the secondary air which is supplied to the starting zone.
  • High angular momentum is desired in the burnout zone.
  • a radially inner swirled backflow region improves burnout and effectively uses the combustion chamber volume.
  • Another group of air guide elements 30 in their alignment, has a smaller angle relative to the radius of the heat shield 24 . These air guide elements 30 also have a smaller angle relative to the surface of the heat shield 24 than the air guide elements 28 . Consequently, these air guide elements 30 route the secondary air with a low angular momentum, in an exit flow direction indicated by another arrow, into the core region of the flame; this especially benefits stable combustion chamber behavior.
