| 摘要 |
The invention relates to a method and device (6) for combusting a fuel-oxidising agent mixture in a combustion chamber (7) of a group of turbogenerators, in particular of a power plant. A total oxidising agent flow (12) is divided into a main oxidising agent flow (14) and a secondary oxidising agent flow (15). Said main oxidising agent flow (14) is mixed with a main fuel flow (21) in a premixing burner (8) in such a way that a poor mixture is formed, a mixture (23) being fully oxidised in the combustion chamber (7). The secondary oxidising agent flow (15) is divided into a pilot oxidising agent flow (17) and a thermal transmittance oxidising agent flow (18). The pilot oxidising agent flow (17) is mixed with a pilot fuel flow (22) in order to produce a rich mixture, the mixture (17, 22) being partially oxidised in a catalyst (24), thereby producing hydrogen. A partially oxidised fuel-oxidising agent mixture (25) and the thermal transmittance oxidising agent flow (18) are introduced together, after the catalyst (24), in at least one zone (26) which is constructed in such a way that it makes it possible to stabilise the combustion of the main fuel-oxidising agent mixture (23). |
