Abstract

In a method for operating a gas turbine (GT) with sequential combustion, which has at least one compressor (12, 13), a first combustion chamber (14) with a first turbine (15) which is connected downstream, and a second combustion chamber (16) with a second turbine (17) which is connected downstream, the at least one compressor (12, 13) draws in air and compresses it. The compressed air is fed to the first combustion chamber (14) for combusting a first fuel, and the gas which issues from the first turbine (15) is fed to the second combustion chamber (16) for combusting a second fuel. Increased flexibility and safety in operation is achieved by different fuels being used as first and second fuel.
