Abstract:
1. A method for operating a gas turbo group, which gas turbo group includes at least one combustion chamber, wherein the combustion chamber includes at least one catalytic, first burner stage and a second, non-catalytic burner stage following the at least one catalytic burner stage in the flow direction, the method comprising: supplying the gas turbo group with a total fuel mass stream ({dot over (m)} distributing the total fuel mass stream to at least the catalytic burner stage and the non-catalytic burner stage; determining the temperature (T regulating, limiting to a set value, limiting to a maximum value, or combinations thereof, the temperature at the outlet from the catalytic burner stage by changing the combustion air mass stream and blocking the fuel supply to the non-catalytic burner stage when the combustion air mass stream is below an achievable maximum; determining a net power output (P regulating the fuel mass flow (m
