Patent ID: 7950239

Claim:
A method for operating a gas turbine plant, comprising, (a) compressing inducted combustion air using at least one compressor; (b) combusting a first fuel using the compressed combustion air in a first combustion chamber located downstream of the at least one compressor, the first combustion chamber comprises a plurality of individual burners, which are arranged in the first combustion chamber in a distributed manner; (c) driving a first turbine located downstream of the first combustion chamber; and, (d) in a first state: (d1) combusting a second fuel using gases which emerge from the first turbine in a second combustion chamber located downstream of the first turbine; (d2) driving a second turbine which is connected downstream of the second combustion chamber; and, (e) in a second state: (e1) completely shutting down the second combustion chamber for a time (t 1 ); (e2) operating all of the burners of the first combustion chamber in a lean premix mode during the time (t 1 ); (e3) driving the second turbine which is connected downstream of the second combustion chamber; and (e4) achieving a low partial load mode of operation of the gas turbine plant.
