Abstract

Method of combusting a fuel with an oxidizer and corresponding burner assembly, whereby a jet of fuel and a jet of primary oxidizer are injected into a combustion zone in contact with one another so as to generate a primary fuel-rich flame, a swirling first peripheral gas jet is injected through a first passage around the fuel jet and primary oxidizer jets and a swirling second peripheral gas jet is injected through a second passage around the first peripheral gas jet and whereby a jet of secondary oxidizer is injected through a passage into the combustion zone between the first and second peripheral gas jets.
