摘要： A rotating device for a compressor of a gas turbine is presented. The rotating device, connectible with the compressor, includes a first shaft, a second shaft, rotatable blades, a bearing assembly, an external drive and an input port for receiving electrical energy for the external drive. The first shaft, positioned axially upstream of compressor's rotor assembly and concentrically around compressor's central shaft, is rotationally coupled to the rotor assembly. The second shaft is concentrically arranged around the first shaft, and thereinbetween is the bearing assembly that decouples second shaft's rotation from first shaft's rotation and transfers load from the second to the first shaft. The rotatable blades extend radially outward from the second shaft, and are rotationally coupled to the second shaft. The external drive is coupled to the second shaft and is configured to control the second shaft's rotation.

摘要： Systems and methods are disclosed herein that generally involve a double pinch criterion for optimization of regenerative Rankine cycles. In some embodiments, operating variables such as bleed extraction pressure and bleed flow rate are selected such that a double pinch is obtained in a feedwater heater, thereby improving the efficiency of the Rankine cycle. In particular, a first pinch point is obtained at the onset of condensation of the bleed and a second pinch point is obtained at the exit of the bleed from the feedwater heater. The minimal approach temperature at the first pinch point can be approximately equal to the minimal approach temperature at the second pinch point. Systems that employ regenerative Rankine cycles, methods of operating such systems, and methods of optimizing the operation of such systems are disclosed herein in connection with the double pinch criterion.

摘要： A gas turbine control method for preventing then operation from deviating from the operating state at the ideal fuel and air flow-rates expected when the gas turbine is designed and maintaining an efficient operating state. A gas turbine control device comprises a frequency analyzing means for analyzing the frequencies inside the combustor of a gas turbine, a state grasping means for grasping the combustion state in the gas turbine on the basis of a state signal representing the result of the analysis by frequency band, the amount of operation process including a ratio between the air flow rate and pilot fuel in the gas turbine, the atmosphere state, and the load amount, a combustion characteristic grasping means for grasping the characteristic of the combustion vibration, and a control section for calculating a correction value of at least either the air flow rate supplied to the combustor or the pilot ratio from the grasped combustion vibration characteristic and the grasped combustion state each time the degree of the combustion vibration exceeds a predetermined control value, correcting the initial design values of the air flow rate and the pilot ratio predetermined correspondingly to the amount of operation process and the state signal, and thereby driving the gas turbine. The control section resets the correction of the initial design values when the degree of combustion vibration of the gas turbine is below the predetermined control value for a given period of time and operates the gas turbine using the initial design values.

摘要： A gas turbine engine is disclosed which includes a bypass passage that in some embodiments are capable of being configured to act as a resonance space. The resonance space can be used to attenuate/accentuate/etc a noise produced elsewhere. The bypass passage can be configured in a number of ways to form the resonance space. For example, the space can have any variety of geometries, configurations, etc. In one non-limiting form the resonance space can attenuate a noise forward of the bypass duct. In another non-limiting form the resonance space can attenuate a noise aft of the bypass duct. Any number of variations is possible.
