Abstract:
A method for generating combustion by means of a burner assembly (12) and corresponding burner assembly are disclosed. The burner assembly comprises a refractory block (12), a fuel supply system (18) and an oxidant supply system (20). The refractory block (12) defines along one plane P1 at least one fuel passageway (28A, 28B, 28C) extending from a fuel inlet port (28) to a fuel outlet port, and along a second plane P2 at least one oxidant passageway extending from an oxidant inlet port to an oxidant outlet port, said first and second planes intersecting along a line that is beyond said outlet ports, said oxidant supply system comprising a pair of oxidant supply means, an inlet of the inner oxidant supply means being connected to a source of a first oxidant having a first oxygen concentration and an inlet of the concentric outer oxidant supply means being connected to a source of a second oxidant having a second oxygen concentration, the method having improved flexibility in oxygen concentration in the oxidant.
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 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.
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.

Abstract:
L'invention concerne un procédé de contrôle du formage de verre plat par écoulement de verre fondu sur une nappe d'étain liquide présent dans une cuve de formage dans lequel on mesure une grandeur caractéristique du formage au-dessus de la surface du verre en cours de formage à l'aide de faisceaux générés par au moins un analyseur basé sur la spectroscopie d'absorption, dans lequel les faisceaux de lumière générés par l'analyseur forment un réseau au-dessus de la surface du verre. L'invention concerne également un dispositif utilisable pour la mise en œuvre de ce procédé comprenant un bras supportant un caisson comprenant un moyen de rétroréflexion capable de recevoir un faisceau de lumière et de le renvoyer dans le sens opposé parallèlement au chemin optique incident.
