Abstract:
1. A device for controlling regenerative burners used as firing equipment for furnaces to reheat steel making products or radiant tubes for lines for the continuous treatment of steel strip, wherein at least one of the fluids involved in combustion, a fuel and an oxidant, is supplied using a rotary injector having rotating injection nozzle which is rotated by a rotary actuator so as to supply one of the burners then the other, in turn, the inlet of air and the outlet of flue gases for a burner are performed by one and the same supply piping, the rotary injector is positioned on the inlet pipe for oxidant, and the rotating injection nozzle is configured to partially block the supply piping leading to the burner so that some of the flue gases from a regenerator of the burner that is switched off are drawn toward the burner that is switched on and the other proportion of the flue gases is discharged to the exhaust.
