Abstract: The invention relates to a method for the combustion of a fuel using an oxygenated gas, in which a jet of fuel and at least two jets of oxygen-rich oxygenated gas are injected. According to the invention, the first jet of oxygen-rich oxygenated gas, known as the primary jet, is injected such as to be in contact with the jet of fuel and to produce a first incomplete combustion, the gases produced by said first combustion comprising at least one part of the fuel, and the second jet of oxygen-rich oxygenated gas is injected at a distance I1 from the jet of fuel such as to combust with a first part of the fuel present in the gases produced by the first combustion. Moreover, a low-oxygen oxygenated gas is injected at a distance I2 from the jet of fuel such as to combust with a second part of the fuel present in the gases produced by the first combustion, I2 being greater than I1. The invention also relates to the burner used to carry out the method and to the use of said method for the heating of a glass filler or for a reheating furnace.

Abstract: An air separation unit separates air into an oxygen-rich and oxygen-deficient gas. Fuel gas and the oxygen-rich gas are preheated at heat exchangers through which hot flue gas flows. Combustion of the preheated fuel and oxygen-rich gases result in the hot flue gas. The hot flue gas is cooled at the heat exchangers and flows through a waste heat boiler. Water and/or steam flowing through the waste heat boiler absorbs energy from the cooled flue gas thereby producing heated steam. The heated steam flows through a turbine to produce power. The power is transferred to the air separation unit, thus reducing a power requirement of the air separation unit needed to separate the air.

Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.

Abstract: The invention concerns a method for burning a fuel by means of at least one a burner, each burner comprising two half-assemblies (1, 1′) comprising each at least one fuel injecting means (2) associated with a primary oxidant injecting means (3), and at least one secondary oxidant injecting means (4), a first oxidant jet being injected at a first distance from the fuel by the primary injecting means so as to generate a first incomplete combustion, and a second oxidant jet being injected at a second distance (L1), greater than the first distance, from the fuel injecting means so as to generate a second combustion with the remaining fuel of the first incomplete combustion. Said method is characterized in that each half-assembly delivers a combustion power different from the one delivered by the other half-assembly.

Abstract: The invention relates to a fuel combustion method in which one jet of fuel and at least two jets of oxidant are injected. According to the invention, the first jet of oxidant, known as the primary oxidant jet, is injected such as to be in contact with the jet of fuel and to produce a first incomplete combustion, the gases produced by said first combustion comprising at least one part of the fuel, and the second jet of oxidant is injected at a distance from the jet of fuel such as to combust with the part of the fuel present in the gases produced by the first combustion. Moreover, the primary oxidant jet is divided into two primary jets, namely: a first primary oxidant jet, known as the central jet, which is injected at the centre of the jet of fuel; and a second primary oxidant jet, knows as the sheathing jet, which is injected coaxially around the fuel jet.
