摘要： PROBLEM TO BE SOLVED: To provide a nozzle for injecting a gas such as oxygen into a molten metal bath accommodated in a metal container. SOLUTION: A supersonic injector (10) is disposed in an electric arc furnace. This supersonic injector has a so-called Laval nozzle (20) disposed above the bath with a predetermined distance therefrom. The dimension of the nozzle (20) is calculated as a function of a desired flow rate of oxygen and a desired speed of jet. The pressure of oxygen at the inlet of the nozzle (20) is set so that the static pressure of the jet at the outlet of the injector (10) is substantially equal to the atmospheric pressure. More preferably, the injector has an annular channel (13) for injecting natural gas, and is used in a burner mode when scrap iron starts to melt. The oxygen speed is subsonic.

摘要： The invention concerns the optimisation of an installation wherein is performed an operation requiring control of the atmosphere inside a chamber (3), operation carried out in the presence of a gas mixture capable of releasing effluents, which optimisation is obtained by the presence of inlet (5) and outlet (8) devices outside the chamber to prevent air intake into the chamber and discharge of gas effluents outside; and a suction device (4) comprising means (42) for regulating flow rate to maintain between inside and outside the chamber a more or less null pressure differential. The invention is applicable to installation treating the surface of a moving substrate.

摘要： The invention concerns a method for separating, by impaction, living particles and particles capable of being revived of a gas or a gas mixture under pressure, characterised in that it comprises a step (a) which consists in accelerating in a stage and along an axis (x) a single gas or gas mixture stream in a confined volume (V), to reach a speed not less than the speed of sound; a step (b) which consists in sudden deceleration of said single stream derived from step (a) in said volume, along substantially the same axis (x), at atmospheric pressure; a step (c) which consists in changing the direction of the gas or gas mixture flow at the output of the volume (V), which on average becomes radial; and a step (d) which consists in trapping said particles separated from the flow during step (c), on a target. In another embodiment, the method further comprises a step (e) which consists in counting the particles trapped during step (d). The invention also concerns a method for determining the microbiological quality of a gas under pressure, characterised in that it consists in using said alternative embodiment. The invention further concerns a device (D) designed to implement said method and its alternative embodiment comprising an element (D1) wherein the single gas stream is successively subjected to steps (a) and (b), an element (D2) constituting the target whereon the living particles or particles capable of being revived are trapped as in step (d), and securing means for making (D1) and (D2) integral, while allowing the flow of gas or of gas mixture to change direction as in step (c). The device is useful for determining the microbiological quality of a gas under pressure.
