  • Method for switching over a gas turbine plant from gaseous fuel to liquid fuel and vice-versa
    Patent number: 9447736
    Abstract: In a method for switching over a gas turbine plant from gaseous fuel (16, 20) to liquid fuel (18, 22) and vice-versa, in which the gas turbine plant includes a first combustor and a second combustor fed with the flue gases of the first combustor, the first and second combustors are sequentially switched over while the other combustor maintains its operating conditions.
    Type: Grant

  • Method for operating a gas turbine plant
    Patent number: 8806873
    Abstract: A gas turbine plant has a compressor (2), a first combustion chamber (6) followed by a high pressure turbine (4), a second combustion chamber (10) and a low pressure turbine (5). In the first combustion chamber (6) a first gaseous fuel (8) is injected and combusted, generating first hot gases (9) that are at least partly expanded in the high pressure turbine (4), and in the second combustion chamber (10) a second fuel (11) is injected in the at least partly expanded hot gases generated in the first combustion chamber (6) and combusted, generating second hot gases (12) that are expanded in the low pressure turbine (5). In the first combustion chamber (6) water is also injected to increase the gas turbine plant power output. In the first combustion chamber (6) a water flow rate is injected compatible with a predetermined flame stability limit.
