Process for partial oxidation in a Claus furnace of at least one gas stream having hydrogen sulphide, and including the steps of: (a) injecting at least one gas stream including hydrogen sulphide and at least one oxygen-enriched gas stream into the Claus furnace, wherein each of the streams is injected at a speed of injection which is substantially parallel, and (b) controlling the speed of injection of the gas stream including hydrogen sulphide and the speed of injection of the oxygen-enriched gas stream such that the speeds have a ratio between 0.8 and 1.2.

A process for combustion in an industrial furnace (1), using at least one burner (2; 3) supplied with combustible (4) and combustion supporting (5) fluids. The flow rate of at least one of the fluids is pulsed at a frequency comprised between 0.1 and 3 Hz. There is provided in the furnace (1) at least one pair of two burners (2A, 2B; 3A, 3B) disposed substantially confronting each other; and the fluid of the burners of a pair is pulsed in offset phase from one burner to the other. The frequency of pulsation is between 0.1 and 1 Hz. The flow rates of fluids are substantially identical for each burner (2A, 2B; 3A, 3B) of the pair. The power of the pair of burners is greater than 300 KW.

To heat a thermic enclosure, flames are generated in a burner having a plurality of injectors, from an oxy-combustible mixture, the flames extending in different directions and having different power and/or oxidizing reducing capacity. Application for example to the heating of furnaces or metallurgical ladles or glassware furnaces.
