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

Variable momentum burner assembly for separately injecting fuel gas and oxidant in a combustion zone, comprising at least two fuel gas canals, at least one oxidant canal and a fuel gas distributor, whereby the at least two fuel gas canals comprise an inner fuel-conducting passage forming an inner fuel gas outlet and an outer fuel-conducting passage forming an outer fuel gas outlet, said inner and said outer fuel-conducting passages being coaxially arranged; and whereby said fuel gas distributor comprises a first fuel gas chamber in fluid connexion with the inner fuel-conducting passage of the at least two fuel gas canals and a second fuel gas chamber in fluid connexion with the outer fuel-conducting passage of the at least two fuel gas canals.

Burner assembly and method of combustion

The invention relates to a method for heating a material in a zone heated by combustion of a fuel with an oxidant by means of a oxyburner comprising an injector arranged within a block defining a chamber with a confinement index Iconf=(S/S')&#xd7;(L/L&#x2032;)&#xd7;(1/(1+a/100))=0.10; the fuel being injected into the burner chamber with a rate IF and the oxidant being injected into the burner chamber at a rate Iox such that 0.7=IF=3.6 et 0.3=Iox=5.1, provided that when Iox&#x3e;3.8 then IF=3.3.

Combustion method and system

The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between &#x2153; and &#xbe; of the length L of the melting chamber.
