Abstract

The invention relates to a method for heating a material in a zone heated by combustion of a fuel with an oxidant by means of a oxyburner comprising an injector arranged within a block defining a chamber with a confinement index Iconf=(S/S′)×(L/L′)×(1/(1+a/100))=0.10; the fuel being injected into the burner chamber with a rate IF and the oxidant being injected into the burner chamber at a rate Iox such that 0.7=IF=3.6 et 0.3=Iox=5.1, provided that when Iox>3.8 then IF=3.3.
