Patent ID: 8122719

Claim:
An apparatus for the combustion of a fuel-oxidizer mixture in a combustion chamber of a turbogroup, in particular a power plant, comprising: a premix burner, in which, when the apparatus is operating, a main oxidizer flow is lean mixed with a main fuel flow and this main fuel-oxidizer mixture is fully oxidized; at least one catalyst, which is designed, when the apparatus is operating, to partially oxidize a rich pilot fuel-oxidizer mixture flowing through it so as to form hydrogen, the at least one catalyst including a heat exchanger; an oxidizer supply device which, when the apparatus is operating, admixes a heat-exchanging oxidizer flow to the partially oxidized pilot fuel-oxidizer mixture downstream of the catalyst, the heat-exchanging oxidizer flow exchanges heat with the rich pilot fuel-oxidizer mixture, in the heat exchanger; wherein the catalyst and the oxidizer supply device being designed in such a way that, when the apparatus is operating, they introduce the partially oxidized pilot fuel-oxidizer mixture and the heat-exchanging oxidizer flow together into at least one zone that is suitable for stabilizing the combustion of the main fuel-oxidizer mixture.
