Abstract (en)

[origin: EP0809070A1] The recirculated exhaust gases are mixed with the fresh air (16) in a mixing channel (5) formed as a ring-shaped jet pump with a device for causing the gas mixture to twist round the burner axis as it moves in a main flow direction parallel to the burner axis. The mixing channel is defined by two conical shells with the inner shell ending in the main flow direction in front of a restriction (3) in the outer shell. The outer shell widens out after the restriction to a diffusor. Several openings are provided for the fresh air to enter the mixing channel in order to form several individual separate suction jet pumps to recirculate the exhaust gases.
