The burner comprises a fuel nozzle for producing a fuel jet of outwardly divergent, fan-shaped configuration. The fuel jet is adapted to burn within the oxidant with an outwardly extending and divergent flame. There is upper and lower oxidant nozzle separate and distinct from one another and from the fuel nozzle for producing upper and lower oxidant jets of outwardly divergent, fan-shaped configuration located above and below the fuel jet, respectively, and having a lower velocity than the fuel jet such that the oxidant is aspirated into the oxidant. |
