摘要： The method involves arranging compressor (1) with annular entry surface, two burners, combustion chambers (14,15) and high-pressure turbines (16,17). The oxygen-reduced gas (21) and sucking-in fresh air (2) are supplied alternately to the compressor. The oxygen concentration of the oxygen-reduced gas is smaller than the oxygen concentration of sucking-in fresh air of compressor. The flow channel of the compressor is attached with compressor intake (3) having two sections (51,52) arranged alternately in circumferential direction. An independent claim is included for gas turbine electric power plant.

摘要： The mixer (7) comprises a housing (15), a duct (16) within the housing (15), at least a first injector (17a) and a second injector (17b) for injecting a fluid having a fluctuating mass flow into the duct (16). The first injector (17a) and the second injector (17b) are at a distance (D) such that the fluid mass flow injected through the first injector (17a) reaches the second injector (17b) in phase opposition with the fluid mass flow injected through the second injector (17b). The first and the second injectors (17a, 17b) are configured and arranged for injecting a mass flow having substantially the same fluctuation amplitude.

摘要： The invention concerns a damper arrangement (112) for reducing combustion-chamber pulsation arising inside a gas turbine (100), wherein the gas turbine (100) essentially comprises at least one compressor (103), a primary combustor (101) which is connected downstream to the compressor (103), and the hot gases of the primary combustor (101) are admitted at least to an intermediate turbine or directly or indirectly to a secondary combustor (102). The hot gases of the secondary combustor (102) are admitted to a further turbine (105) or directly or indirectly to an energy recovery, wherein at least one combustor is arranged in a can-architecture. At least one combustor liner comprising air passages (114), wherein at least one of the air passages (114) is formed as a damper neck (113). The damper neck (113) being actively connected to a damper volume (112), and the damper volume (112) is part of a connecting duct extending between a compressor air plenum and the combustor.
