ABSTRACT:
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.
