Abstract:
A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.
Abstract:
L'invention concerne un procédé de chauffage d'une charge à l'aide d'une flamme engendrée par une lance et/ou un brûleur, caractérisé en ce que dans une première phase, on dirige la flamme en direction de la charge et en ce que dans une deuxième phase, on dirige la flamme sensiblement parallèlement à la charge.
Abstract:
Brûleur comportant au moins un passage (10) pour l'injection d'au moins un jet primaire, tel qu'un jet de comburant et/ou de combustible et/ou d'un prémélange comburant et combustible, et des moyens d'injection (21) d'au moins un jet de fluide secondaire (2) débouchant dans ledit passage, l'interaction entre le jet primaire et le au moins un jet secondaire permettant de faire varier la direction et/ou l'ouverture de la flamme. Utilisation dudit brûleur pour chauffer une charge avec la flamme à direction et/ou ouverture variables.
Abstract:
The invention relates to an apparatus for injecting at least one jet of fluid, in which the direction and/or opening of at least one of the jets may be variable, comprising means of injecting at least one main fluid jet, means for injecting at least one secondary fluid jet, and means for causing at least one main fluid jet to interact with at least one secondary fluid jet and producing a fluid jet resulting from this interaction whose direction and/or opening are variable; as well as the associated method; and the uses of these.
Abstract:
The invention relates to a method for controlling flat glass forming by flowing a molten glass over a liquid tin layer contained in a forming vat wherein a forming characteristic quantity is measured above the glass surface during forming by means of beams generated by at least one absorption spectroscopy-based analyser, wherein the light beams generated by said analyser form a net above the glass surface. A device for carrying out the inventive method comprising an arm for supporting a vessel which comprises a retroreflecting means for receiving a light beam and transmitting it in an opposite direction parallel to an incident optical path is also disclosed.

Abstract:
Four verrier comprenant au moins un brûleur à flamme orientable dans la partie aval de la zone de fusion et procédé de fabrication de verre par fusion d'une charge dans un tel four.
Abstract:
Burner comprising at least one passage (10) for injecting at least a primary jet, such as a jet of oxidant and/or fuel and/or of a premix of oxidant and fuel, and means (21) of injecting at least one secondary jet of fluid (2) opening into said passage, the interaction between the primary jet and the at least one secondary jet making it possible to vary the direction and/or the size of the flame. Use of said burner for heating a charge with the variable-direction and/or variable-size flame.
Abstract:
L'invention concerne un appareil d'injection d'au moins un jet de fluide dont la direction et/ou l'ouverture de l'un des jets au moins peut être variable, comportant des moyens d'injection d'au moins un jet de fluide principal, des moyens d'injection d'au moins un jet de fluide secondaire, et des moyens pour faire interagir au moins un jet de fluide principal et au moins un jet de fluide secondaire et engendrer un jet de fluide résultant de cette interaction dont la direction et/ou l'ouverture sont variables, ainsi que le procédé associé et leurs utilisations.
Abstract:
A jet of gas injected from a lance is fluidically deviated with a gas flowing in either the same or opposite direction as the jet of gas. The gas used to fluidically deviate the jet is the same as or different from the gas in the jet.
