Abstract: A premixing burner intended to be mounted in a combustion chamber, the burner being configured to be supplied with oxidant and with fuel, the burner comprising a central annular shroud and a peripheral annular shroud, the central shroud being positioned inside the peripheral shroud so as to form an annular space between these central and peripheral shrouds, the burner further comprising at least one injection of fuel and at least one injection of oxidant into the annular space so as to premix the fuel and the oxidant in the annular space.

Abstract: A burner designed to be fitted in a combustion chamber, the burner including: a central nozzle configured to have an oxidizer and fuel supply; several peripheral nozzles configured to have an oxidizer and fuel supply and which each have at least one upstream fuel injector in order to pre-mix the fuel and the oxidizer in the nozzle; at least one oxidizer input connected to the said central and/or peripheral nozzles; wherein peripheral nozzles each have a flame stabilizer located at the end of the peripheral nozzle designed to exit into the combustion chamber, as well as a tip injector to inject fuel at the end of the peripheral nozzle.

Abstract: A premix burner made up of an air inlet tube of length L and a single specific gas injection, the gas injection includes an upstream gas injector, a mixer, a downstream gas injection situated at a distance L3 from an upstream end of the air inlet tube and a stabilizing element, where the gas injection constitutes a one-piece mechanical assembly that ensures a self-stable elementary flame.
