The invention relates to a power plant (1),with at least one turbo group (2) comprising at least one turbine (3) and at least one main burner (5) which is arranged upstream of the turbine (3),with at least one recuperator (11) which is arranged, on the one hand, in a first flow path (15) leading gas
The invention relates to a power plant (1),with at least one turbo group (2) comprising at least one turbine (3) and at least one main burner (5) which is arranged upstream of the turbine (3),with at least one recuperator (11) which is arranged, on the one hand, in a first flow path (15) leading gas toward the turbo group (2) and, on the other hand, in a second flow path (12) leading the gas away from the turbo group (2),with at least one auxiliary burner (19) which is arranged outside the second flow path (12) and which is connected on the outlet side, at or upstream of the recuperator (11), to the second flow path (12).

1. A power plant, with at least one turbo group which has at least one turbine and at least one main burner arranged upstream of the turbine, with at least one recuperator which is arranged, on the one hand, in a first flow path leading gas toward the turbo group and, on the other hand, in a second
1. A power plant, with at least one turbo group which has at least one turbine and at least one main burner arranged upstream of the turbine, with at least one recuperator which is arranged, on the one hand, in a first flow path leading gas toward the turbo group and, on the other hand, in a second flow path leading the gas away from the turbo group,with at least one auxiliary burner which is arranged outside the second flow path and the outlet of the auxiliary burner is connected at or upstream of the recuperator, to the second flow path.2. The power plant as claimed in claim 1, wherein, to supply the auxiliary burner with gas to be heated, an auxiliary blower or auxiliary compressor is arranged upstream of the auxiliary burner.3. The power plant as claimed in claim 1, wherein the power plant is designed as a gas storage power plant, the first flow path being connected, upstream of the recuperator, to a gas store.4. The power plant as claimed in claim 3, wherein the turbo group has at least one additional turbine which is arranged upstream of the main burner.5. The power plant as claimed in claim 4, wherein the turbine is drive-connected to the additional turbine.6. A method for starting a power plant wherein said power plant comprises at least one turbo group which has at least one turbine and at least one main burner arranged upstream of the turbine, at least one recuperator which is arranged, on the one hand, in a first flow path leading gas toward the turbo group and, on the other hand, in a second flow path leading the gas away from the turbo group, and at least one auxiliary burner which is arranged outside the second flow path and which is connected on the outlet side, at or upstream of the recuperator, to the second flow path, said method comprising: operating the auxiliary burner to generate heated gas, by means of which the recuperator is preheated before the turbo group is started.7. The method as claimed in claim 6, wherein, during preheating, the flow also passes through the recuperator along the flow path which, during normal operation, leads the gas to be heated out of a gas store.8. The method as claimed in claim 6, wherein, before the starting of the turbo group, the recuperator is preheated to a temperature which is below a selfignition temperature of a fuel/oxidizer mixture delivered to the main burner during the starting of the turbo group.9. The method as claimed in claim 6, wherein, for the heated gas generated by the auxiliary burner, a temperature is set which is below a selfignition temperature of a fuel/oxidizer mixture delivered to the main burner during the starting of the turbo group.10. The method as claimed in claim 9, wherein the temperature of the heated gas is set in that cooler gas is admixed with a hot gas which is generated by the auxiliary burner and the temperature of which is above said selfignition temperature, before the gas mixture thus formed is fed into the second flow path.11. The method as claimed in claim 10, wherein the admixing takes place even internally within the auxiliary burner.
