Burner

A burner comprising a combustion zone into which three components are introduced by a first injection group:

• i. a fuel;
• ii. an oxidizing gas, for example air;
• iii. an inert gas, for example gases from combustion, nitrogen, or water vapor;
• wherein:
• two components are mixed together and the resulting mixture is injected and pulsed at a plurality of stages into the third component in the combustion zone, and in that the fuel is in motion and traverses the combustion zone, while the oxidizing gas and the inert gas are mixed together by one or more injectors, so that the mixture thus obtained is drawn into the combustion zone at a plurality of injection stages arranged at different positions relative to the movement of the fuel.
