Abstract: An industrial furnace for heating products such as steel products includes a thermally insulated enclosure, a plurality of burners arranged in the enclosure for heating products passing from one end of the enclosure to the other, the burners being distributed over a plurality of temperature-regulated heating areas, and a recovery system designed for recovering heat energy from recovery fumes, The recovery system includes a rotary regenerator associated with each heating area, each of the rotary regenerators being configured to receive a predetermined flow rate of recovery fumes via a first duct, receive a predetermined flow rate of supply air via a second duct, preheat the supply air in order to supply the burners of the associated heating area with a predetermined flow rate of preheated combustion air via a third duct, and discharge exhaust fumes via a fourth duct.

Abstract: A device for managing unburned residues, the device comprising a regenerator (5) having one end connected to a combustion enclosure (3) and an opposite end connected to a fuel admission pipe (4) and a flue gas exhaust pipe (8), the pipes being fitted with valves (2; 10) to alternate between an admission stage and an exhaust stage through the regenerator. A purge circuit (1) connected to the regenerator (5) acts before the exhaust stage to purge the regenerator of the fuel that it contains. The invention provides a corresponding method of managing unburned residues and a burner including such a device.

Abstract: A fluid regulator device having means for injecting one or more make-up fluids into a duct conveying the fluid to be regulated. Make-up fluids are injected selectively along at least two orientations. The means for selecting the orientation of injection are situated outside the main duct. A method of regulating a fluid, the method comprising a step of injecting one or more make-up fluids into a duct that conveys a flow of the fluid that is to be regulated.
