Abstract
Process for combusting a fuel with an oxidant and burner for the implementation thereof, process wherein at least one stream of the fuel is injected through at least one first perforation, a main flow of oxidant is injected below or above the one or more streams of the fuel through at least one second perforation, an auxiliary flow of the oxidant is introduced into contact with the at least one fuel stream so as to generate an initial flame by an initial partial combustion of the fuel with the auxiliary flow of the oxidant, this initial partial combustion being completed downstream of the initial flame by means of the at least one main stream of the oxidant, the flow rate of the main flow of the oxidant or the ratio between the flow rate of the main flow of the oxidant and the flow rate of the auxiliary flow of the oxidant being adjusted depending on the emission intensity of the initial flame.
