Abstract:
1. Method for operating a gas turbine set, comprising: compression of an air mass flow in a compressor, feeding the compressed air mass flow into a first combustion chamber, burning a first mass fuel flow in the first combustion chamber in the compressed air mass flow, expanding resulting hot gas in a first turbine, feeding partially expanded hot gas into a second combustion chamber, burning a second mass fuel flow in a second combustion chamber in the partially expanded hot gas, supplying to the gas turbine set the first mass fuel flow and the second mass fuel flow with a fuel supply pressure, and dividing the total mass flow into the first and second mass fuel flows according to a normal operation mode, wherein when a limit value of fuel supply pressure is not reached, deviating from the division according to the normal operation mode such that the first mass fuel flow is reduced by a difference mass flow and the second mass fuel flow is increased at least by the difference mass flow.
