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:
The invention relates to a method for heating a charge using a flame generated by a lance and/or a burner, characterized in that, in a first phase, the flame is directed towards the charge and in that, in a second phase, the flame is directed more or less parallel to the charge.
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:
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:
The invention relates to a glass furnace that comprises at least one burner with a directable flame in the downstream portion of the melting area, and to a method for making glass by the melting of a load in such a furnace.
Abstract:
The invention relates to a method for melting a load in a furnace, the furnace including in the upstream portion of its melting area one or more side oxy-burners with a directable flame.
