A method for generating combustion by means of a burner assembly and corresponding burner assembly are disclosed. The burner assembly comprises a refractory block, a fuel supply system and an oxidant supply system. The refractory block defines along one plane Pat least one fuel passageway extending from a fuel inlet port to a fuel outlet port, and along a second plane Pat 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.

Method for generating combustion by means of a burner assembly and burner assembly therefore

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.

Distributed combustion process and burner

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.

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.

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.
