1. A burner comprising:
- a non-circular peripheral wall and orifices provided through said wall in order to eject a primary gaseous mixture along an ejection axis associated with each orifice, said orifices are arranged so that the ejection axis of any first orifice diverges from the ejection axis of a second orifice closest to said first orifices;
a venturi including an annular radial divergence chamber which is defined by a throat;
a recompression chamber for recompressing a primary gaseous mixture, said chamber being defined between said divergence chamber and said peripheral wall of said burner; and
a direct path of said primary gaseous mixture defined between said throat of said venturi and an orifice, said direct path comprising a first partial path through said divergence chamber and a second partial path through said recompression chamber, wherein said first and second partial paths are each longer when said direct path is longer.
