Abstract (en)

[origin: WO2005095855A1] The invention is characterized in that: a catalytic converter arrangement (1) is provided upstream from the flame (13) and can be flowed through by a air/pilot fuel mixture (4) that is separate from the air/fuel mixture; the catalytic converter arrangement (1) comprises at least two catalytic converter stages, which are arranged one behind the other in the direction of flow and of which the catalytic converter stage (3) situated upstream, the so-called POX catalytic converter, can be flowed through by the air/pilot fuel mixture (4) with an air/pilot fuel mixture ratio of lambda < 1 whereby partially oxidizing the air/pilot fuel mixture (4), and the catalytic converter stage (8) situated downstream, the so-called FOX catalytic converter, can be flowed through by a leaned air/pilot fuel mixture (7) with a mixture ratio of lambda > 1 whereby completely oxidizing the leaned air/pilot fuel mixture while forming an inert flow of hot gas (9).
