Abstract: The invention relates to a reactor for purifying a gas flow by contact with a liquid. The reactor comprises a chamber which delimits a channel having an inlet opening and an outlet opening for the gas flow. The chamber has walls made of a flexible material which is secured to an inflatable structure which is provided with means for retaining pressurised air therein in order to form a self-supporting flexible structure with trapped air.

Abstract: A device for blowing gas on a face of traveling strip material has at least one hollow box having its wall fitted with a plurality of blow orifices enabling gas to be directed towards the face of the strip material. The hollow box is also fitted laterally on at least one side thereof relative to a midplane (Q) perpendicular to the plane in the strip with a movable shutter member having the function of selectively shutting some of the blow orifices in order to adapt the width of the blow zone to the width of the corresponding strip material. The movable shutter member has an edge adjacent to the inside surface of the wall fitted with the blow orifices, and an edge adjacent to a side wall of the hollow box.

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.
