Patent ID: 7421844

Claim:
A method for the combustion of a fuel-oxidizer mixture in a combustion chamber of a turbogroup in particular of a power plant, in which a total oxidizer flow is or has been divided into a main oxidizer flow and a secondary oxidizer flow in which the main oxidizer flow is lean mixed with a main fuel flow in a premix burner, and this main fuel-oxidizer mixture is fully oxidized in the combustion chamber, in which the secondary oxidizer flow is or has been divided into a pilot oxidizer flow and a heat-exchanging oxidizer flow, in which the pilot oxidizer flow is rich mixed with a pilot fuel flow, and the mixture is partially oxidized in a catalyst with hydrogen being formed, in which the partially oxidized pilot fuel oxidizer mixture and the heat-exchanging oxidizer flow, downstream of the catalyst, are together introduced into at least one zone which is suitable for stabilizing the combustion of the main fuel-oxidizer mixture.
